This is exactly the book I have. Both in soft cover and hard cover.
Been around a long time. I searched for the best book for Chevy rebuilds and this one came up multiple times.
I always wondered what inspired the Lego man's haircut. Now I know.
Included here (on page 6) is Chevy's break-in procedure for a Fresh 350 HO (sbc w/ vortec heads & hydraulic flat tappet cam).
JMO, I'd pull the intake & lifters and reapply moly lube or similar to lobes, lifter faces, & pushrod tips. Smear some lube on distributor gear as well.
*Do NOT leave heavy lube on Sides of lifters OR in block's lifter bores; the resulting stiction can prevent lifters from spinning during break-in. That, in and of itself, can lead to wiped lobes.
*Do NOT use common felt/paper type gasket with Vortec intakes; they're great on conventional manifolds but prone to failure when used with Vortecs' entirely different clamp angle & loading.
*These are very good silicone on an aluminized-steel base carrier:
my two cents. you got f'd. this thing is probably just a good core with an intake. just from the looks of it i would say you need a 100% rebuild. go punch the guy you bought it from in the face. and get the block magnifluxed while you're at it. no S. take the whole thing apart. check the rod and crank bearings for any wear. i'll bet they are date stamped 1975 or something and showing copper. been there, done that. got the guy to give me half my money back (core price). easy to fix but machine work is NOT.
Did the OP ever say what he paid for the engine? Maybe he only paid peanuts for it.
I agree with you 100% and I HATE being agreeable! I think that motor has never been rebuilt.
Those heads are NOT rebuilt! They look NASTY! They look like something off a junkyard motor with a gazillion miles on them!
Assuming the heads are what I said, pull the intake off and look at the lifter valley area of the block. IF it's nasty, the motor hasn't been rebuilt.
Pull the heads to inspect the pistons and block. I'll bet there is a ridge on the top of the bore = NEVER been rebuilt.
At that point, it's off to a REPUTABLE machine ship to rebuilt.
I have the same book and it’s a good one. That dude looks really serious, but every time I pick up the book I wonder what the heck he’s looking at??
He's looking away cuz he knows he'll wretch if he looks at that motor's tricolor scheme.
But it IS a good, basic book
