I would expect to put out over 350RWHP with my top end on a 331.

What was your AFR.

I'm guessing one of your problems...and probably the main one...is the stock Cobra computer. From what I have heard...they suck! Do the conversion to the regular Mass-Air 5.0 computer. I may be wrong but I believe it's the A9L. A guy on another board I'm on did the computer conversion and picked up a TON of power. You should seriously look into this Fox-4-Cobra.
