Pre Top Swap Questions

L67 swap it. the whole motor is not only easier, its more reliable. top swapping is a fad.

the only reason you need a high compression block is if you ran out of room with your L67 setup and are running a 2.4 pulley.
 


Ok, Thanks bio. Can I just use the pcm on the gtp for a while then? I have a tuned one for my GT and like it so I figured ill send one in and get it tuned for the GTP. Also does a VS cam need a certain tune also? Ill just wait until get the cam and drop it in before i get one tuned then. What springs would you recommend for the VS cam as well?
 
The gtp pcm won't have the correct gear ratio. It'll drive funny and throw a code.

You'll need a good retune for the cam. I would do everything at the same time so you're tuned for it all.
 
If I already have a 2.5'' down pipe with a cat. Could i just get a PLOG and run that with a cam? Or do i have to get headers for more flow?

Is turbo the next fad?
