I've been thinking about it and talked it over with some more knowledgeable builders. I want the F1, but I thought it was going to be too big and wild for street use on a 402. I know the F1 is louder, that's exactly what I want. The sheetmetal intakes are nice, but I will lose low end only to gain power over 6000. Not worth it considering its a street car. I want reliability and streetablity.

My options:

Use my 402, F1, 225cc heads,blower cam, Fast intake.

Save money, sell my 402, build a 427, F1, 245cc heads, blower cam, Fast intake.

An F-1A has the same 9" volute diameter as the P-1SC and the D-1SC. Back at the old shop we built an engine for a customer (who is on here -skydiver-) and we started with a new LS2 block, added a Callies 4.0" stroke crank, Compstar rods, Diamond pistons, Total Seal rings, our blower cam, AFR 225 off the shelf heads, FAST 92 intake, Kooks 1-7/8 headers and an F-1A.
12.4 psi of boost and it made 864 rwhp on a Mustang Chassis Dyno and 400 ft lbs of torque at just 2000 rpm. Skydiver took his V to another shops dyno day and it made even more power on their dyno. He has driven this V on several long road trips, it has been a very good combination. Bob
