302, GT40P heads, Edelbrock intake, 24lb injectors. MAF conversion
New TFI module, new coil, Tried with and without MSD box. with and without kenny bell BAP, AEM wide band. No smog system.
I pulled the codes and the only codes are related to the Smog stuff and tad/tab, and I get the VVS code since I don't have a harness connected to the unit.
So what the car does:
The car has not had any parts added to the car since I started having these problems... it was running fine, and now it's acting up. I road race the car and the problems started while I was at the track.
The car drives fine for about 10 minutes (car heats up in about 3-4 to a temp of about 190F), then there is a noticeable drop in power and the car starts going lean.. and I'm talking off the wide band lean 16+ and the car backfires (sounds like on the intake side).
It only does this above 2200 RPM's. so under a light load the car acts like the power is there but once I hit that 2200 RPM range the power drops off and the car is going lean.
I have new spark plugs, wires, cap, rotor, TFI module, and a coil.
I've run with and without the MSD box (and set my plug gap to down in the .048" and .054" without the MSD).
I've pulled the IAC plug while running (and hot) and the car still runs and doesn't really drop in RPM.
I've tried 2 TFI modules just to make sure my replcement wasn't bad.
I've pulled the distributor about 10 times to make sure it's installed in the correct position and timed right. I set the base timing to 10 deg with the plug out.
