Well my engine builder has decided to not have me paint his car in trade for the BBC I wanted. I'm sure it was his wife she gives me a dirty look every time I see her...So I'm going back to my very original plan of either a 4.8/5.3L with the mid rise dual plane since I have two perfectly good 1850 Holley carbs. About the only thing I might do is change out the heads to some that are ported since the cam will have 227/235 duration at .050 and .614/.621 lift. According to Comp Cams Dyno Sim it will make 507HP at 6500rpm and 447 lbs of torque at 5000rpm.
Still going to use the 4L80E with the "Black Box" and either a toggle for OD or add a mph switch.

That's life...
