    So after seeing a symilar thread in the garage I thought I'd make my own.

    So I am currious about what you guys think I have for HP.

    My engine is a 83' 305HO that is out of a Firebird that is an L69. So stock form is 185hp.
    Mods: Holley 600cfm carb, Weiand Action+ Intake, K&N air filter, true duel exhaust 2 1/4 inch pipes, removed all smog equiptment, pertronix flame thrower HEI distributor.
    Also timing is dead on and so is the carb tuning so what do you guys gauge it at?

    I am thinking about 235ish HP.
