433 shortblock
i hate to let this go since had been wanting to build it forever but here goes.
71 988 block .030, line honed with arp 2 bolt studs. machine work done by len williams machine here in oklahoma. one of the top motor motor mount bolt bosses has a piece missing from it so probably not good for the f body guys. comes with a nib rpm 4" forged crank 3" mains and pontiac rod journal, nib icon 2618 .4.15 bore pistons, and nib eagle h beam rods floating pin. the crank has had a 2nd keyway cut for a blower. will need balanced and rings and bearings.
$4000 obo.
i have another 988 block thats been vatted, needs to be .040 to clean up. 4.375 forged rpm crank and program engineering splayed caps. 1000.00
i have a set of never ran hr 72cc d ports and a used rpm intake, or victor 4150 ill let go for 2800 to the buyer of the 433 shortblock....otherwise ill keep them for now.
for 8k i will throw in the arp stud kit along with a sd mega brace nib. the D ports will only be available until i get some shop space to finish assembling 406, also for sale later.
pm for # and i will send pictures.
hate to abandon the 433 build, but i have a 467 to use along with 2 ia2s so i need to concentrate on those
