What intake are you using

 

[RageStang]

i have the cobra intake

Then use a 65mm or open the Cobra upper up a little and use a 70mm.

ive decided to get the 75mm tb with an 76mm mass air flow unit and the trick flo intake. then the msd ignition. your thoughts?

Skip the MSD unless you like to walk.

Ive never had a problem with my Digital 6 box. If mine ever takes a dump on me i have the adapter harness where i can just hook the stock coil back up and run the factory ignition.

If MSD was really as bad as the internet made them out ot be i bet the digital 7 boxes would not be in 95% of every small tire car that is at the dragstrip

True, while I have had a MSD here and there it happens with all components, you hear about the MSD since 95% of guys out use them....the failure rate will be higher, and the internet spreads bad info like a CA wildfire.

I like the idea of Intake, TB and MAF, although Id personally do a Pro-M meter with the boosted combo. Id use the Track Heat over the Street Heat to give you more room tog row in the future.

I have a Digital 7+ (7531), I had a 6AL, and in the old school days I had a 6A. None of them have ever caused a problem for me. My brother still might be running my old 6AL. He might have mentioned it finally had a problem. I'll ask.

We had an MSD "ready to run" (no box) distributor fail in one of our '69s. It didn't quit running completely, but ran really badly driving the 200 miles home from Roundup in Bellevue last month. We put a stock points distributor back in, and all is well.

Have the intake opened up to match the throttle body.
