Got a motor!
Picked up a 350 for my 84 Cutlass off of CL. Casting # says its a 68-71? motor. It has standard bore and a .010/.010 crank. Fresh valve job on the heads. I need some help identifying the heads, though. I am NOT sure they are the 'correct' heads for this motor. The only #s I can find are these:
550-362 on both heads. With a 118 and 253 on the other, but those #s are far away from the 2 on the exhaust ports. I found a site that said these MIGHT be a set of 57cc 260 cid heads....anyone know for sure? <Never mind. I found it right here on the Wiki site. Thanks.>
It came with a lot of new stuff: oil pump, cam, timing set, etc.
The bottom end was assembled by a bunch of chimps, I think. The thrust bearing was on the #1 main cap and there was no rear main seal installed for crying out loud! I pulled it back down and fixed the mains up. I'll finish the short block this afternoon, and I hope to have the car going down the road next weekend.
One more question: Any one have or know where to get an EGR block off plate?
Thanks,
sb

So......
I know what the heads are, and those are some SMALL valves. Is it worth using them at all? Maybe make some good grunty low end torque?
I have had good luck using small combustion chamber/small valve heads on 360 Mopars (318 -302 casting heads). Would this be a similar case? Those valves are 1.7/1.5....but the motor was bigger and....well, anyone been desperate enough to try this on the OLDS?

Heads
Picked up some -716 casting heads for $160, rebuilt. The old boy said he had 2 or three more sets, so if anyone is interested....let me know.
I put the shortblock together, but didn't have the fuel pump eccentric yet, so I have not yet put the timing chain on. I may not get the car going until next weekend due to the wait on a few more parts.
No worries. I did sell my truck this week, so I'm motorcycle man everyday until I get the car going. (Rain OR shine!)
