Would appreciate suggestions on what PROM to use for a mildly modified 350 TPI, ZZ3 cam,
5 speed with a 9 bolt 3.27 posi rear. Just finished building setup and used GM stock 305 5 speed prom for expediance. Runs good and strong enough for break in but want to max performance at a reasonable price(whatever that means). I am not quite ready to go the "smoke your own" route yet.
Thanks

 

I used the stock 305 5-speed chip in my 350 engine with ZZ4 cam and ZZ4 heads. There really isnt a chip you can use unless you go the custom route. As long as your car runs fine on the 305 chip, keep it until you get your own prom-burning equipment, or you can find a friend to make you a chip.

I called FIS in texas and told them I needed a stock chip for a 350, but have a 5 speed. The guy said no problem, $75 shipped. I also had the VATS removed.

I would go get a chip for a 350 just like the post above mine. I bought a hypertech chip and paid too much.
