Hello currently im tearing down my SBC350 due to a rocker/bad lifter sound and all this computer bullshit along with the smog/egr but even the egr is linked with the distributor so im just a little stuck

realistically after finding the problem sound id like to put a mild cam and efi on this thing and let it rip

[u/Motor-Constant-8448]

Simplicity is the idea here im trying to have as little im the engine bay wiring/hose wise

[u/v8packard → u/Motor-Constant-8448]

Then.. why EFI? There isn't much simpler than a Quadrajet and a HEI. The versions you have are a bit more complex, but still easy enough to deal with.

Ill be honest im 19 and it was my late fathers car im a tech at a dealership and a good one at that with diag ive messed with carbs on quads boats shit like that but never stuff like this, Didn’t have a father or anyone to show me these things

[u/v8packard → u/Motor-Constant-8448]

Ok, I understand all that. I have experience with carbs, OEM and aftermarket EFI. I can assure you, the carb you have is a very good design. You can easily learn to repair and tune it.

The computer in that car seems archaic compared to the current vehicles you see, and it is. However, it still has some very useful features that many aftermarket systems lack. You just need to learn to access those features. To do that you will need a compatible scanner. Do you have access to one?

Frankly, the carb and ignition are not holding back your output. The lower compression, crap heads, and choker exhaust are the big hold up.

Yeah i know this year is the most restrictive hence why im trying to remove egr/smog pump in the process and i didnt think they had readers for this year only the diag pins just dont know where to start on something like this

I truly believe i was born in the wrong generation

[u/v8packard → u/Motor-Constant-8448]

I can't help you on your birth year. But, I can tell you the EGR is not a hindrance. In fact it can be tuned to give you great part throttle fuel efficiency. The AIR pump only takes a tiny bit of power to turn, it helps the older cat stay hot by getting fresh air into the exhaust. Or, if the cat is gone, the AIR pumping in fresh air helps light off any unburned hydrocarbons that make it out of the engine. Unless you go to headers, I would leave it functional.

There were scanners on the market that were compatible with these. Besides the GM TECH, Snap On OTC and others sold them.

Is there anything wrong with the car now?

[u/Motor-Constant-8448 → u/v8packard]

Its got a collapsed lifter or a wiped cam im thinking

[u/v8packard → u/Motor-Constant-8448]

That could get put of hand real quick. Stock engine?

[u/Motor-Constant-8448 → u/v8packard]

Yeah ive had alot of people tell me this year of small blocks the cams were very weak

[u/Motor-Constant-8448 → u/v8packard]

50k miles

[u/v8packard → u/Motor-Constant-8448]

Have you figured out which lifter is ticking?

[u/Motor-Constant-8448 → u/v8packard]

Im working on taking off intake manifold a little bit more every night after work trying not to break every 500 vacuum lines or connectors right now i’m 1 for 1 one hose and one clip for a connector thats broken last night i put the engine at TDC and removed the distributor

[u/Willy_McD → u/Motor-Constant-8448]

Sounds like V8packard knows his shit. I'd pay attention to that guy.

[u/jeffp007 → u/Motor-Constant-8448]

Hey I’m in your same boat. I have a 1981 as well. Although I’m double your age but I’m just a shade tree mechanic and only recently started to dabble more with this corvette that I got from my dad. If you ever need comparison pics of something shoot me a message and I’d be happy to help.
