I know its Not a Bowtie But,any need 455 OLDS?
 

I picked up a F block(68-72)455 the other day. 73-up EGR top end but low milage dealer installed bottom. Haven't pulled the pan but car itself had 69,000 miles and motor had been replaced. comes with brackets,flex plate,longth400,and 850 QJ.This motor has no VIN stamped on the machined pad on the block. I will get a casting date first chance I get. $300.00 or trade for blazer or truck parts. (I need a short bed for my c-10)moodyholler
