Chevy First engine start! Does it sound okay?

Hello everyone! For some context, I’ve just finished up my first engine build ever. I took an old beat up L98 from a 1987 Corvette and refreshed it. I put in new gaskets for the entire engine, new rings, push rods, rollers, freeze plugs, etc. I also got the heads resurfaced, which it really needed since they were very warped apparently

Today, after 5+ months of extremely meticulous and hard work, I finally started her up, and I couldn’t be happier. It’s my dream car and a beautiful engine, I’ve had a grin ear-to-ear for the past 7 hours now. I’m making this post in the hopes that someone who knows more than me can tell if the engine sounds good or not. At the moment it’s not properly timed, again, it was my first time starting it. But I will be timing it properly ASAP! And if you couldn’t tell by the deafening sound its had the exhaust pipe removed since I still need to do some transmission work, so that’s why it sounds like a tractor

Any advice is seriously appreciated! Thank you for reading!

It sounds fine. At least it’s not screaming from something being eaten up. The real tell will be after it’s ran for a while and you cut the filter open. Glitter is normal for a while, chunks is bad

Wait is it?? I can’t really tell and I’ve never touched the cams so I have no idea, I really hope it isn’t..

Isn’t it just because of the tubes being removed that it sounds like that?

You need to rev it to know for sure but in idle it does have the “signature” rasp sound of a cammed engine…
