will installing a cam and injectors from a 3.4 into my 2.8 give me any more power or torque ?

it wont do anything except make u run rich

what about the cam or is that worthless as well ?

if you really want a cam in your car, call delta cams and have them make you one for $45. thats pretty much the easiest way.

honestly i dont think the 2.8 in my camaro is worth the cost of an oil change im just wondering sense i could get those parts for free

You got yours for $45?!?!?
I paid $100 (with lifters) delivered for a mild turbo grind.

the 3.4 cam is the same cam u currently have in the car

Doesn't the 3.4 cam have a timing index on it for DIS?

well yeah the cam was $45 and lifters another $45 IIRC.

I remember the lifters being $40. They didn't make me ruturn a core either, said they waived the charge since I lived so far from them and would cost more to mail it then it was worth (the core).
