I just picked up a SBC last weekend - complete with crank, heads, pistons and rods. I just had a chance to strip it down. Came out of a '71 Monte Carlo.

Block Casting # 3970010
Heads Casting # 3986336 (appears to have 1.94 / 1.5 valves)

Even gave me the exhaust manifold, intake water pump and flexplate.
I'm trashing all the latter. But wondering what to do with the crank and rods.

It is a 2 bolt main which I have heard is fine for ~350hp. Is it worth having splayed caps installed when the block is at the machine shop?

Are the heads decent to have reworked? Again looking for ~350hp. Is it cost effective to install new studs, springs valves etc? Or should I find a set all done already? I haven't talked to the shop in regards to the heads yet, may just see if they will clean them up for me along with the block and remove the springs and see what it will cost to have them redone.

Can the rods be checked and brought into spec? Or should I just buy new ones. I don't want to get this all built and then throw a rod. Rods are GMK and either 2O, 2M, 3K mixed and matched. I did keep the caps and rods together as they came out.

The crank I am assuming is cast but again is it worth having checked out?

I am not sure what car this is going into just yet. Something like an early Camaro etc.. something small to maybe a Nova size. I wan to get the block cleaned up and machined. What would be safe to do at this point without knowing the final project yet? It has a standard bore so taking it to .030., install new cam bearings and freeze plugs. Check main caps.

Just looking for some advice to begin. Any input?
