So I found out the other fat my father in law had a k&n cold air kit on his old farm truck. He said I could swap him fir my stock system.when I pull his off I see the throttle body has holly stamped on it. Would you swap it out if you were me? Would it be compatible his is a 97 mine is an 01 both are 360.

 

Yours is more than likely a holly unit as well.

 

I wondered about that after looking them over a bit. Ill probably just leave it as is. thanks for saving me the work for no reason!

 

If it looks like this it's a stock TB.

 

I believe the earlier production TB's had "Holley" on them, but the latter runs did not... everything else (casting number included) is the same.
