Common CFI mods?

Heya guys i was just wondering what some of the quick HP mods are for the crossfire injection? also would intalling a 160 degree Tstat do anything? and last i just recently swiched my 83 CFI camaro to a 5 speed.. it had a 700r4 in it, and i dont know what to do with the PRNDL swich. i have it taped in the park possition at the moment.. does that make the car run any different or no? if so how do i bypass that?

CFI is just another form of TBI. The first mod should be the exhaust because it offers the most gain/$. The second will be ducting cold air to the air cleaner, because it's cheap and quick and it does work. A cam swap, and intake porting at the same time, would be the next mods.

I also suggest going here:

Yes. Increase the rate of engine wear and reduce your gas mileage.

There have been posts on dealing with cosmetic interior changes after a auto trans is swapped for a manual --- do a search in both the interior forum and drietrain.
