400 stroker cranks

My friend built a 508ci stroker out of a 400....020" over block, 4.25" stroke that I think was an ex-Top Alky crank. (He got it at-where else?-Carlisle.) Note that almost all aftermarket forgings are from China. :( (Hence his use of the used billet.) A HUGE help for bore clearance was using rods (Carillo H-beams, IIRC) that use button-head capscrews instead of bolts. He also used main bearing studs and a stud girdle...note that the crank was NOT turned down, the block was align-bored to the RB bearing size. Oiling system is factory except for a big pan & Hemi pump/pickup; it balanced with no Mallory metal...you want to keep things light!

He did convert to a roller cam...top end is a set of Indy heads off Racingjunk, single-plane intake I think is an old M1, and a 1000cfm Thermoquad with stock air cleaner. Pulls like a diesel from 1200RPM in any gear even in a 4000lb car!
