Buddy dropped a valve in his motor and is getting rid of it all!
Gen IV 454 block, 2 piece rear seal 4 bolt main. I believe it's a 4.250 std bore. One cylinder got a good groove and will need a sleeve.
4.000 inch chevy cast crank Std main / std rod
Open chamber oval port heads that will need 2 new valves and a good clean up
Willing to sell it all for $250........... Come get it
