breakdown 3-4K...

[69Pony]

Guys,

Having a problem with what I think is electrical issues.

MSD 6AL
MSD ready to run billet dizzy
NGK plugs
MDS 8.5 wires

Initial timing at 16* / 34* total with the two light blue springs so it is all in around 2600rpm.

Car starting fine (18* initial makes it a hard start). Good idle at 950.

However, between 3-4k I get choppy acceleration and really flat power band. Almost feels like the rev limiter but it's a 6200 chip and is working.

10.7:1 compression with plug gap at .040. Thinking about bumping that to .045-.050 per MSD.

Any other ideas?

Thanks,,,,,
