Timing control yes/no ??

[Interceptor5588]

I made the change in ignition components to allow my FITECH to control timing. It has done as the others have stated in allowing so much more control of the tune. How smoothly my car drives now is night and day difference. It has really taken the edge off the 041 cam in my Pontiac 455. Off idle response is much better, clutch engagement is smoother, engine load at cruise is lower according to the MAP readings. No downside that I have found yet.

What distributor did you use for the Pontiac V8? I've heard the 301 turbo distys can be made to work.

Push comes to shove, can use the bottom of the distributor that matches the block, and the top of a Chevy distributor. The bodies can be welded together. Need to take into account the inner shaft length.

I know a guy that did this for a 455 Olds engine.

I am pretty sure that GM went to HEI ignition on all engines around 76-77, so there are HEI distributors available for Pontiac engines.

This should work with some minor modification as described in the Holley Sniper instructions.

That works for the Holley Sniper system, but that distributor is not a computer controlled unit. Many EFI systems require a computer controlled ignition control module (ICM).

I'd be curious to see what other EFI systems you're talking about.
