Std bore block ans std size crank. block will need bored for rebuild. I have the old rods and pistons if you want to reuse the rods but will all the good low priced rods available not really worth it imo. Drilled for 4 bolt caps from factory. 6x-4 heads are off a 350 and will put the compression with flat tops around 9:1. Heads will need a complete rebuild. Will put on pallet for shipping if seller makes all arrangments to be picked up. 700 obo. No paypal, us postal mo only.
