How about a new 4.050 crank?About $800, I think Molner makes some with 2.00 rod journals so you can use SBC rods, shelf pistons. Granted, it is more expensive, but if the rods are cheaper (SBC Hbeams) it might soften the cost some. There are a number of stroker pistons out there for some good 5.7 combos. I found a 3.888 stroke crank at Lofgrens at a good price, plus I bought the rods out of his Drag Pac motor which will give me about a 6.3 Hemi. I am not sure if he has any left, though.
