Trickflow 240 or 270's on B block
I can guarantee if you build anything close to this you will be very happy. I am very confident my combo should put me in the low 10's (possibly high 9's) with my b-body so it would be tough for you to go wrong whichever way you choose if going into an a-body. Andy's builds seem like they are very pump gas friendly and so far I have found this combo to be very streetable despite the bigger cam.
