Well, along w/ the LT1 cam.......I just bought a complete NOS syst. for GM TBI from a guy up the street for $250. I figured if I don't like it on the TBI, I'll put it on the carbed motor. It's pre-set at 120 shot. Should I get a new/better fuel pump in there. It's a 91 'maro TBI. He had the system in an '89 or so bird.

 

I would post this over in the Power Adder forum if u haven't already. They are really good with that sort of stuff.

oops........I thought I did post it in power adder. Sorry.........

 

ummm first how are you going to use it on both tbi and a carb intake??? this is pysically impossible!!! 2 totally different intakes the plate wont fit on a carbed intake! dont know much about nos(yet)! but i know that the 2 use different intakes!(ie 2 different plates!) ommm can you just take the tbi plate off and use a regular carb plate in place of the tbi plate? if so call me a itiot! please! i deserve it!

Future mods performer rpm air gap intake (polished) comp roller cam, and way better headsa 400 defintely in the works!

 

OK, your an itiot. lol

...and you also would need to change the fuel jets due to the different fuel pressures.
TBI = 12-15 PSI
carb = 5-7 PSI
Your stock pump should be more than sufficient at that power level if it is working at full potential. Be sure to put a fresh fuel filter on.

Of course you're right..............I just didn't mention the fact that some things would need to be changed. I have extra parts (i.e. rails, plates, intakes, etc) from different set-ups that I could use. Thanks guys.
