Charger

Very nice build. i am looking at the QA-1 shocks for my duster as well. I dont mind spending money as long as they work.

Blower motors are pretty fussy, they like lots of cylinder head volume. You may have limited yourself with the rpm performer heads. I have them on my new 426 build, and they are a 210 cc runner, the victor JR head is a 280 cc head. When i built my last 468 BBC i was choosing between blower or nitrous. I went nitrous. But the research was cool.

I called Donny Hampton, Hampton blowers,and my 468 with his spec cam and the AFR 305 Rec port heads and his blower with 12 lbs of boost would of made 900 HP he had built several like that and said it was fairly drivable at that boost level.
