48 if the block is cracked then probably the head is also. old bolts 6's are famous for cracked heads. if you can find one, old military trucks that were g.m. made had 302's in them, also i'm sure you can spot a junker gmc big truck in a farmfield, scrapyard etc.. maybe find a a 270, 248, etc..


iam a pool shooin' boy by name of will mc coy
but back home they call me slim
well i'm lookin' for the king of 42nd. street
he's drivin' a droptop cadillac
after he took all my money
and this may sound funny
but i come to get my money back

and everybody say jack
don't ya know
ya don't tug on supermans cape-------


good song!
