Thread: 350 Rebuild Question

Tweet

Big Tracks-Thanks. I appreciate all of your help, and I will try to listen to you guys better without just saying I don't want to do whatever youre saying. Well what do you think about this engine to rebuild, and I'll definitely look into those classes. I found it on Craigslist,

350 corvette roller block, roller lifters,crank,one piece seal
Its a bare block a standard bore. It would work great for a hot 350/383
build. You could use a gm roller cam and build a real buget engine. It is
out of a 91' vette. With the block, you get the crank, roller lifters,
timing cover, oil pump, oil pan gasket, and a few other odds and ends that I
have for the engine.

I talked him down to $175. What do you think, or do you think I should go with something else? And, this is also the same engine I already have in my 85 Vette.

Well, It sounds good to me but I'm definitely not the old toot to ask. I have a 4.3 in my work truck and for the last 141,000 miles it has been a real little work horse. Prior to this one the last Chevy I owned was a mighty 235 in my '51 four door and that was in 1954 (give or take).

TCC probably wouldn't be too offended If you asked to talk to somebody in the department and maybe see if they would permit you to sit in on a class.

I'm assuming they have classes that deal purely with engines but I'm in no way certain.

Thanks Jim.

Well what do yall think about this engine to rebuild? I found it on Craigslist,

not a bad piece to start with.... do you have a good torque wrench? if not.... you're going to need one

thesals-You think so? I was going to ask to see it this weekend. He desperately needs to get rid of it. Yeah, I'll probably have to go buy one. Oh yeah, and is it any harder to rebuild a 350 from 91 as to one from the 70's? Or is it mainly the same?

the newer they get the stricter the tolerances get.... luckily you're not getting into something that is torque to yield all over the place....should get a cylinder dial bore gauge.... as well.... find out what the motor is actually spec'd to... should be at 4" unless its been bored out

no, its standard bore

alright if it is standard look for heavy wear in the cylinders and such... check thoroughly for cracking and warping

Ok, I will. My uncle was saying I should go Magna-Flux the block to check for cracks. Do yall know about how much this would cost? He was saying $50-100, but if you guys have gotten one done recently you may know a more accurate cost. Thanks to all of you. Zak

last time i paid for a magnaflux it was $50.. that was a few years ago.... lately when i need a magna flux i do it myself

What does a Magna-Flux invlove?

you engulf the block with a magnetic field brush on iron oxide which will collect wherever there are cracks and such, and then look at it with a black light to see where the iron oxide is collected at.... you need special equipment so you'll need to pay to have it done

Oh, I know. I was just wondering exactly what is done. Thanks.

If you buy a block from a machine shop and have the machine work done at the shop, they'll usually guarantee the block is crack-free and magnaflux at no charge.

Otherwise, $175 is a great price for a standard bore roller cam block, especially if it comes with a good set of roller lifters.
