    you need supporting mods to drop pulley size, down pipe plog combo, or headers, then you can do a 3.4 tops on just 93 gas.

    smaller if on e85 or if you invest in a inter cooler.

    98 Buick Regal GS, F body brakes, Caddy STS wheels, tinted tails L36 bottom end, lightly ported heads, 1.95 roller rockers, headers, gen 5 N* 3.0 pulley, FSIC, 42 lb injectors, a BrandonHall rebuilt trans, DHP tuned and AEM water/Meth injection https://goo.gl/gpV5kW

    3.0, 2.8, 2.6?

    Which one?

    Probably the 2.6"

    It'll be fast for a few days.

    Run 87 octane too.

    2.45" seems to have some serious racecar effects...
