Good evening everyone, on my 86 F250, I'm in the process of having my exhaust almost ready to be done. With everything being stock, other than a 650 edelbrock, long tube headers, 2.5" dual exhaust with xpipe and having the timing at 12° would anyone happen to have a guess as to how much horsepower and torque I should have? Once I get it back I'd like to test drive it and feel if it has the power that it should have. If stock is 210 hp/305 ft/lbs, I'm going to guess 240 hp/ 350 ft/lbs? Thank you very much!
