@ this point,you have a 50/50 chance that it is what he says.As I said earlier,just becuz he bought the parts & had machine work,doesn't mean squat if it wasn't put together rite.Did he crank it for you?I would @ the very least,hook up an oil psi guage & do a quik compression ck to see if all cylinders are producing good even psi.Shouldn't be that hard to do.If it was running ruff & he's blamin it on the wires,a cheap set @ Autozone for $30 will prove that out.It's a risk only you can decide if worth takin.You could get a good fresh 396,or,a bucket of trouble.

Are you specifically shopping for a 396? If not,there are better choices comparitively priced & with a warranty of some sort.I'm not saying the 396 is a "BAD" motor,but,when compared to other Chevy engines,it did have a relatively short run for some reason.I don't think it lived up the expectations GM had hoped for.I've even heard,(& this is prolly some old wives tale)that the only reason the 402 came to be,was due to @ the time GM decided to pull the plug on the 396,they were sittin on a very large inventory of blocks rusting away that needed to be used up on something.The link I posted is representative of what I've seen price wise & does have a 12 month/Unlimited mile warranty for not much more.The 375 HP version specs the 292 cam that is spose to be in the motor your considering,so,we know 460 HP for this engine is not realistic.It does have an intake,carb,& distributor.Their condition tho is no better known than the engine tho.Your gonna get a few who will go out on a limb & say "Don't buy it",but'I don't think many who will say"Do It".

The real reason for the demise of the 396 was the odd bore size. John D. was trying to cut down massive inventories of odd ball parts and consolidate. Several GM engines used 4.120-4.125" ring sets and Chevrolet got the word to more or less standardize.. The motor died shortly after because of the drastic lowering of compressions across the GM line in 71. A low compression 396-402 is just a gas eatin, emission spewing, TURD....

oh wow that's good. it did have dome top pistons he took the heads off and showed me i just had to pay him for new intake gasket when he did take them off now i couldn't tell if it was a small dome or large dome since im no expert in that subject and i used a compression tester and it had 150 psi in all cylinders. i tried getting back in touch with him but i haven't been able to hes probably not wanting to sell it to me anymore since i wasted his time i do hope he gets to sell it though it would be a shame for it to just sit there while hes away in the army

What you wrote is two hundred and forty thousandths (almost a quarter of an inch). Writing twenty four thousandths goes like this..... 0.024"
I'm not meaning to be snotty, but someone has to teach you guys how to write math.
