Re: questions for converting to TPI
I am curious, everyone that I've spoken with says you can't run an aggressive cam at all with a TPI. Have you heard something different? And if so please enlighten me.

Re: questions for converting to TPI
Ok so ive been hearing more and more about the use of vortec heads on older short blocks. Isnt there quite a bit of modifying that needs to be done to run these heads? Forgive me but Im uneducated about the years in which the heads changed can someone clarify this. Im also reading up on things and finding that some people are using LS1 intake system on the older styles. how similar are the blocks and heads form generation to generation. Maybe there is a informative web site someone cant point me too that explains this.

Re: questions for converting to TPI
Im guessing its because of the restrictive RPM curve people have been mentioning. Bigger cam = higher rpm power range.
I do have a book Ive been reading into a bit called Tpi swapers guide it has some info in it about installing bigger throttle bodys and bigger intake runners to get that higher Rpm Operating range, but Ive only glanced through that section.
