What do you think my HP is?
 

I just bought another stang, it already has longtube headers and a mild cam. I am not gonna do much to this one but what do you think my horsepower will be if I drop a set of GT40P heads on it with a Trickflow Trackheat intake. I will also be putting on all the little bolt ons like Underdrives, Throttlebody and such. I know that we can't be too accurate on such little info, but I guess I am just trying to figure out what I am gonna get out of those heads and intake. Also do yall think that I should go with those GT40P's or should I just port the E7's? thanks

I would like to have a little more info but I tell you what. I honestly think if you still live in Panama City (FL) you are lucky and you should go see Mark Biddle of Panhandle Performance, located in Lynn Haven. The guys there, Mark and Adam are a bunch of real cool, down to earth guys that could very well guide you in the right direction.
Good Luck

I'd say with the P's around 250RWHP-260RWHP. I would get better heads though. You can find a good set of used aluminum heads for good prices now adays.
