ok for one thing you dont know if i have a truck but i do . i am not a little kid i am 21 and i have a 78 chevy so dont tell me i dont. i have called the cam company and you sit on hold for like an hour till someone can help. ya i have changed my combo maney of times, most people do what is wrong with that? there is just tomany things to pick from so thats y ia ask what i ask. i am trying to build a street rod not piss people off. thanks for the hp number to is there any way that i could make more with this combo. it kinda sad that you have to get down on people trying to get info. i do look on the internet for combos that have the same heads i do or the same kind of truck but i never find any. most of the sites are bull anyway.
