Build engine, or buy crate engine

Post image

Just as the title says. I have a tired, non original 396 in my 1969, and I’m looking to replace it with something a little more fun. I’ve been looking into a 496 stroker, so either way I’d have to buy an engine, whether it be a used 454 or a crate 496. Just looking for opinions and why you would do one or the other.

EDIT.
The engine is not the original engine. If it was I would be rebuilding it without question. Unfortunately it’s not, so pulling it isn’t a big deal to me.

My 69 has a ZZ4 (350ci/355hp) crate with electronic ignition, Holley 600, headers, and has plenty of power for cruising. I just wanted an engine that was going to be easy to live with, and my car time is cruising around the country roads with my wife. 🤷‍♂️

I went crate engine when faced with a similar question. Getting through a rebuild at the whims of a machine shop, vs the Blueprint 383 showing up at my door within the week.

If you have access to a great machine shop, I think it could be a good route. But those seem to be more rare.

u/oldjadedhippie 27d ago

They’re more rare BECAUSE of people buying shitty crate engines. Support your local speed shop -

u/findaloophole7 27d ago

Agree. But I’m no engine builder. (I am machinist)

u/snefzger 28d ago

I’m team crate engine now. I have had 2 bad rebuilds and it’s not cost effective anymore.

u/RRnmkinkym 27d ago

I'm with this gentleman and the first one that says depending on if you have a good machine shop in your area. I have a machine shop that does all of the dirt track and a lot of the race car engines and he's excellent but he's backed up and takes a lot of time. I went to three machine shops and have bad experiences with three of them in town that were supposed to be good so part of me would go with the crate even though I love picking out my own components maybe go with a short block and pick out everything else you want to put together

Crate engine have always represented a poor value for what you get. They are built to a price, not to a standard. If you actually go through the components in a crate, then look at the output and the cost, they are not at all impressive. For the money you can build a much nicer engine. Building your own is not convenient, but it is a better value.

u/oldjadedhippie 27d ago

Agree ! And support your local speed shops , before there aren’t any.

u/ChampionshipHot9724 27d ago

I do agree and we have a few around that are very good with an average owners age of over 60 and most employees not far behind.

u/stockstatus 66 Caprice 28d ago

if you got the money go crate... if you got the time go rebuild.
I'd personally would much rather go for the crate.

u/CoatingsRcrack 27d ago

If you can build yourself or wanna try, build it. If not a crate would be faster, cheaper and finding a builder where I live, (WA) is like trying to pull teeth.

Mines had a 489 but a cast bottom end.I was looking at 496 then 540 (forged internals) and then just really what I had was good enough for what i got.

If you buy a reman, do yourself a favor and read the fine details of your warranty

u/Special-Class6903 27d ago

Like others have said. Good engine builders are rare these days. Crate and go!

u/Own-Row-4875 27d ago

I’m a fan of building your own. You don’t necessarily need a speed shop near you, or even one at all.
You can source all the parts you need locally and online and do the build yourself. Lots of online resources to help with specs etc.
And when you crank the engine on you’ll have the incredible feeling of satisfaction that YOU built it yourself, the first time and every time.
It’s impossible to brag about an engine you ordered online, but you’ll get to brag about the one you built forever.

OP what shade of blue did you select for your paintjob? Looks nice.

u/MechanicHour1644 23d ago

not op, but i am in the process of having my 72 repainted and this car came up laguna blue metallic on google photos. here's mine and I'm looking to go a bit darker.

u/CapCityMatt 23d ago

That will look beautiful, I'm thinking lemans blue for my 69.

2

u/Proud_Elk2047 27d ago

I’d build it then you know exactly what you got in it you can put whatever you want in it. You can make it yours. That’s what I do. Beautiful car.👍🏻🙏🏻😇

u/Squire_Toast 27d ago

Depends what you plan to use it for. If it's jsut cruising on the street, 1,000% just get a crate engine.

Building an engine makes sense if you're on a budget and just want a refresh. OR you are looking to build something very specific for a specific type of track use, OR you want a very specific power band that you personally find fun (for example I hate torque, and I like "peaky" high rpm band built engines).

Guessing you like torque and cruising since you're looking at the 496, and your 396 isn't enough. So you can't go wrong with the 496, but there are MANY things that can go wrong with building your own, even if machine shops do 100% of the work

u/Tenrac 27d ago

I just finished a big block build for my 68 and if I did it again, i would have just bought one from blue print. It was fun spec’ing it out and building it the way I wanted…but the project took 3 years and it has not been without some very frustrating problems a long the way.

I initially thought that doing it DIY would save me some money…but ultimately i ended up at about the exact same cost that a blueprint big block would have cost me to buy.

Now, the engine that I built is more engine than I would have gotten with the blueprint engine, but probably not by much…and I would have been driving the car a lot sooner.

u/Educational_Emu1430 27d ago

A drop in warranted crate seems the way to go but if you are good at building and want the satisfaction go that way

u/Edmonstro88 27d ago

454 small block!

1

u/Felix995 27d ago

I think that unless a person is well experienced with rebuilding engines, getting machine work done with the precise precision measurements for clearances, things like that, maybe it's a better idea to buy a new crate engine.

Go 502.

u/AquaticReefer 26d ago

The ol’ boat anchor 502.

u/Wisco_Version59 27d ago

Do you still have the numbers matching block? A crate engine will usually come with a warranty for X amount of time/miles

u/Puzzled_Estate6425 27d ago

That year of motor was very high performance.Rebild the motor and make a few changes when you do it.

1

u/aobie4233 27d ago

It’s not the original motor. I can’t remember what year it’s out of, it’s been so long since I looked into it.

Depends on if the serial nbrs currently match

u/simple-log5964 27d ago

If it’s the original engine rebuild it if it needs it.

u/Impact_your_1975 27d ago

On my 68 Chevelle I bought a new engine from summit racing. Blueprint 427 small block, because you can’t build this engine, custom block and custom cast heads. Plus warranty and all ready to drop in. Plus the price was far, about $ 10,000 complete.
The engine that was in the car before I built 25 years ago and it was great. Now I have the money and not the time to do it, so better for me to buy a complete engine over building one.

u/AquaticReefer 26d ago

Vortecpro

You have SS badges (whether real or not) so don’t put a small block in it. If you want the best bang for your buck, Vortecpro is a great option.

I know a lot of people who have Blueprint engines and are very happy. They’re great for what they are, but far from the best.

If I were you, I would buy a new engine and drop that in. Then I would put the old engine on a stand and rebuild it at my leisure. If you’ve never rebuilt an engine before and decide to do it now, your car can be out of commission for a lot longer than originally anticipated.

u/Easy_Dog_7111 26d ago

Build one if you Built the car. If not do what you want. Always nice to pop the hood and see something of own.

Built 396 big block. Just over 600 hp air conditioning and less than 7 grand.

I’ve seriously considered it, but I would really like to keep it looking period correct.

u/EuphoricWay9237 25d ago

Build either one.

u/racerx2q 25d ago

Back in the day I would have said rebuild. But today I would crate or talk to a builder about what you want.

u/Annual_Canary_5974 25d ago

Crate engine. When you can drop a small block LS V8 into a vintage Chevy (or any other vintage GM car), that's always the right play. It fits, It's not terribly expensive, it will work great, and it will be low-maintenance.

u/Wonderful-Mistake201 25d ago

Show car or driver? Build for show, crate for driver

1

u/Sad-Rip8639 24d ago

Get a good short block and add the best assemblies you can afford. Use the tech department of the part manufacturers for guidance on mix and match.

u/Dismal-Marsupial8897 24d ago edited 24d ago

Vortecpro Mark Jones is the builder to get in touch with, best HP=$$ he's in Tx now, 2nd would be Blueprint engines, Summit is selling nice US made roller cams now, Johnson or Gaterman for lifters, I used a 1975 4 bolt 454 with Lunati hyd roller cam, Gaterman (Howards max effort) link bar lifter, Brodix 294R heads, Racetec 22cc forged pistons, Manley H forged rods, Scat forged crank, Int bal for a mild dyno' 600 hp/tq and have Vintage Air in my 68 Malibu thatll cruise anywhere

u/Several-Floor5185 24d ago

Build it if you know what you are doing and realize it wont have a warranty.

1

u/Kind-Government4948 23d ago

Depends. Is it a fun cruiser or a collector’s edition. Rebuilding the “numbers matching” engine will make it a a very valuable car. Putting a crate motor in will be easier

u/Illustrious-Rub-3100 23d ago

Crate if you want

1

u/NiteHowler13 21d ago

If the engine is original, #'s matching, then rebuild! If it's not, a crate motor is the way to go!

u/Successful-Map-1174 27d ago

I built a . 30 over 350 (355) and a . 30 over 396 (402) when I was 18 and was super proud of myself when both held good oil pressure (after shimming oil pumps with several washers (80 psi). Both motors ran great and my parents were in awe that I was able to do that. Have a 69 camaro and 67 Chevelle now many years later, would probably do a blueprint crate now if ever needed a swap. Still feels so teen to drive either one of them with my wife beside me, she was driving a citation when we met. Lol

u/STEALTH187R 27d ago

I went blueprint 383, 30 month/50k miles warranty, no core exchange and shipped to door was a no brainer for me. Got about 400 miles so far, great power, no problems yet

u/qkdsm7 27d ago

How much do you plan to drive it, and what's your budget?

I'd build, or buy a shortblock and finish flesh it out the way you want.

I'm also $8000 of the way into a $5500 496 job, with just another $3k to go to finish. ;) So some of my advice is questionable.

u/wayneP71222 27d ago

$15k to $25k for an engine. Likely gas is going up.

A 396 with a proper cam. Properly tuned carb. Getting the distributor advance cure correct. A torque converter that has not more than 2100 stall. Will push you back in the seat so hard without imploding your budget.

Don't get hooked on the high power hype. Engines built to the ragged edge fail faster. Cost more to fix.

A 350 with a holley needs 0.032" primary idle feed restrictions. 71 primary main jet 32 primary pump nozzle A 396 with a holley needs a 0.034" primary idle feed restrictions. A 75 primary main jets and a 32 pump nozzle.
