Partially opened "crate" engine picture in the wild. They are not center bolt valve covers, but are the blue print design Vortec heads. Nothing wrong with the vortec heads.
I wish everyone in this thread would stop saying VORTEX heads. Anyone who types that should not be taken seriously. As you should all know Chevy came out with the VORTEC head in 1996 in most car and trucks. They offer better flow than the older heads but are really nothing special compared to an aftermarket aluminum head. Commonly used for a budget performance upgrade.
Then it’s definitely not gear driveit does whine. I am thinking that noise is possibly the input bearing on the transmission. Sound changes when foot off the clutch, and when I push in the clutch it gets quieter.
I'll know more this weekend, I did take a small gamble (which usually bites me in the arse). But car appears solid and just needs some small mechanical TLC. Interior is mostly original, like 99% and in very good condition.
Well, those specs are significanly different that what was first posted as a 350hp/350. I agree with SoCal that if it is a BPE then it should be good. Or at least it would have been when new. You're detailed description called out hydraulic rollers so the later post about possible flat tappet lifters would be in conflict with this. But simply Googling BP3830CT1 pulls up the Summit page with it and it says flat tappet. If the seller told you roller, I'd start to get nervous. But, maybe he's just an idiot. That's likely actually
Vortec 350 heads are considered by many to be the best production SBC head Chevy ever sold. They flow well but can't take much more than around .500" lift without modification. This is a pretty tame 383 but it makes good torque and should be a lot of fun in a fist gen. Assuming a previous owner didn't screw something, I be you'll be happy with it. Well, until you decide you want 500hp, or 600 or....
