Do you still have the car and if so, what is your current tune? I am planning a very similar set-up and would appreciate knowing where you ended up.

No, I sold the engine and had to scrap the car. I don't think I have any of my tune files anymore, either.

Be careful of your header choice. My biggest problem was burning up ignition wires on the exhaust. Beyond that, get a wideband O2 and let it tune itself.

Hey andrew,
What did you have your input set to when you had the vacuum advance distributor in it? I have a holley stealth ram/TPI with a vac advance distributor, and my input is on the ignition coil ground, but i have a 2400 RPM cranking speed. I can pedal it, get it to start and it will run fine/accurately read RPM. Did you run into this? Thanks in advance! -Dan

I honestly don't remember, Dan. Sorry!
