Ok, so I think I scored big here. I'm not going to say exactly what I got.
Mark 4 (BBC)
Production years 1969-1974
4 bolt main
GM's pride and joy
This may give it away... Its featured in GMs "cheverolet power" manual.
Any guesses? I'll post pics of the casting in a week.
??
427
It couldnt be one them there 482 bbc??? if it is I gotta know how much you paid, Ive been looking for one forever!!
nvm i see you posted its a 427 lol crushed my hopes and dreams lol but is yours the tall deck? The tall-deck blocks all had 4-bolt main caps, forged crankshafts, and the strongest of the 3/8 bolt connecting rods. Still real good find tho if it is :)
you might have got real lucky and got one of the first BBC they ran in nascar in late 60's and early 70's that would be freakin awsome!!
7/16 connecting rod bolts
