is there anything interchangable with the 3.0 and 3.4? for example can you put the 3.4 heads on the 3.0 or anything like that that will get me more power?

as far as i know, the only things that are interchangable are the motormounts, radiator, fan shroud, and the fan itself. as far as I know, there r a lot of people here who have gone from the 3.0 to the 3.4

yeah i have considered the 3.4 swap but could not make it to where i could actually afford it. now i am rebuilding my 3.0 and am wondering if anything is interchangeable that could get a considerable power increase out of it.

No. Not cheaply. Certainly not as cheaply nor as reliably as the 3.4.

The 3.0 is what it is ... while you got it apart, do some port matching and call it good.
