    A few combo questions

    Have a few questions about my injector sizing.

    327 c.i.d. sportsman block
    x-303 cam
    AFR 185's
    1.6 rockers
    Holley systemax intake
    Accufab 75mm
    83 mm pro-m
    42lbs injectors
    Anderson PMS
    Aeromotive comp kit w/sumped tank
    TKO
    Paxton Novi-2000 w/Anderson powerpipe
    I would like to see 570 or higher at the rear wheels but I think my injectors are smallish..need 50's or 55's correct? Also the novi has the stock pulley on it,what size pulley do you guys reccomend? This is a street car so pump gas is a issue

    570+ RWHP is pushing the Sportsman block IMO. You might want to think about a stronger block (A4, R302, Dart). What internals are you going to run?

    you may be suprised with what the stock pulley will net you. dyno it with the stock pulley and at least you'd have a starting point where pump gas won't be an issue.

    Not too worried about the block my previous motor by DSS was a stock block 302 w/ no girdle that surrvived until I pulled it out and sold it at approx
    30,000 miles making 492 hp at the rear wheels. The only thing I replaced before selling it was the rod and main bearings. The new motor has all eagle forged crank and rods w/J&E pistons.

    i'd think it'd be just fine. and you know what? it will or won't, that's my motto. be alil conservative @ first and it'll be fine. It'll be screaming with stock pullies anyway.
