870 ecm, 305 to 350

well since i know what proms to use now my next question is will a basic 350 burn such as the one for the 85 vette on here http://www.ece.udel.edu/~davis/z28/index.html
i have 24 lb injectors, a small crane cam, not sure of actual specs, light lope. flat top pistons and stock 305 heads. im just looking to get in the ballpark of where it should be. it runs rich with the 305 prom in it now. although it is a daily and i have gone about 7k it seems to only run super rich on low octane. ie my wife can drive behind me on 93, and not get fumigated. maybe timing is being retarded to far. it has a 350 esc and knock sensor.

whats pff? i realize the advantages of using the 165 ecm, but i want to make it run decent with the comp it has for now. the burn on there seems pretty close and the 1st and 2nd are with iron heads. i have the 700r

Re: 870 ecm, 305 to 350

well thats encouraging. finally got around to ordering proms. ive got a lil extra motivation due to getting wasted by an m3 the other day. luckily i havent gotten beat by any mustangs had an 05 by 3 fenders. theres in the high 13's i think. really i think it runs great until all of a sudden loses power, but runs awesome cold. so how easy is it to use the editor, i guess thats what i should get next.

PFF is Pennock's Fiero Forum, aka fieroforum.com. There's 17,000 members there and only like 68,000 registered Fieros left on the road, with most Fiero owners having more than one, I figured odds were pretty good you knew of it.

Anyway, sorry to highjack.

its like night and day, in 88 the suspension was 3 link in the rear, with trailing arms. mines a formula. just dont put all new front suspension without doin the rear 2. wiped out at 90 talkin to the mom and trying to hold a coffee due to not havin cup holders in these. did 3 spins went backwards spun back around, nailed the brakes and just nudged the guardrail.
