"742" Chunk 4.86 gears

Replied to PM. But as far as the W-2 stuff is concerned, I'd wait until you start assembling the engine before ordering pushrods to make sure you get the correct lengths. Head and deck milling as well as which rockers you use will have an effect on the optimum overall lengths. The intakes may be about .060" longer than the exhausts because of the offset.
I use to run W-2 stuff a long time ago.
