    not to be an ass but did you build it yourself? im guessing yes because the original parts a impossible to find. if its real kuddos! i believe its about 330hp stock. with your mods???? you have a stall wich robs a little rwhp and a cut out which does the same, i would say you might put down 290-310 with a good tune. i'm just guessing im no expert.

    The average is 300-315 rear-wheel stock for an LT4 (i.e. no tune).

    He asked what the numbers were for a Firehawk LT4. His T/A is converted as stated in his sig.

    you guys are cute. im a GIRL.


    i do have a giant stall, that i want to get rid of, and its an A4. im putting 340 at the motor with a stock cam but only 275 at the wheels, i also have a terrible mail order tune, shes goin in for a dyno tune after i fix some minor maintenance issues. i dyno with the cut out closed, its only open for racing.


    "The average is 300-315 rear-wheel stock for an LT4"

    why would you get rid of the stall? because you loose hp? who cares what your dyno said you will kill an m6 with a stall and shiftkit, as long as you have the same mods

    i have a shift kit, but the stall is doing more bad than good with a stock cam, it had the stall in it when i bought it, i dont think stock cammed DD's have any business with a 3200.

    umm yes and no. you want a stall that suits your cam but why get rid of it? 3200 is not that high. 4200 yes. are you going to cam it? if you do then keep the stall and se if it helps. if you want the gas milage then get a stocker and keep the stall. btw what brand is the stall?

    that stall is perfect for the stock lt4 cam. do not change it at all. if you go any lower you will regret it. I want a 3200 stall for my stock lt1 cam!!! that is not too big for your engine at all. If you got the hot cam for it I would say go to a 3400 or 3600, because the hot cam makes its power even higher, but that stall is perfect for yours.

    hell an lt4 hotcam would be perfect to go with the head work I've had done. lt4 hotcam does require a dynotune to make it work right. it is a way more aggressive cam than the stock cam. I'd trade my stocker any day for a 3200 too, my car is a daily driver though. so it would be hard to do that.
