Thread: Engine Block

Tweet

I have a block which i find hard to id. It has 1114 stamped on the front of the passenger side block. The back has an 010 stamp and the rest has been milled almost right off. The balancer is 1/4 inch larger then most i've seen and the intake is a stock aluminum GM. The oil holes in the valley look larger as well. Is there some other place that will tell me application to confirm hp from the block. Iam hoping its at least 300 stock and possibly upward. Thanks for you time on this.

most of the blocks i have came along with 010 is a 4 bolt main 350 running 370 hp. stock. if the rest of the #s are 3970010 then it is most likely a 350 4 bolt main running 370 hp. but gm did make a 2 bolt main that ran that much too. with the same #'s, i haven't yet came acrossed any to this day

They also made a block with those same numbers in the 70's that made 145-165hp, kind of like mine.

true gmc, opps i forgot to say that the 350 with 370hp came from a vette. sorry i just want back and looked it up again.
