I do believe I resolved my fuel system issue. I added a T-rex pump and did not melt any plugs this time. Although my previous best mph was 125. This weekend I only ran 122 something. I had my inital timing at 10 degrees for the spray, and when I ran 125 I had the timing at 15 degrees initial. So the extra timing I was running before may have contributed. This weekend I also ran with about 1/2 94 octane and half Torco 110.

It smells nice.

I also think I should be running a little quicker on the hose. I would imagine that a 150 shot should get me around 12 or 13 mph, not 10 mph. Maybe a dyno-tune with a wideband might get things in order. An N.O.S. Tech guy told me that his Mustang traps 108 on motor, and 122 on a dry 150 shot!

I know I could benefit from a cam with more than the E's 220 degrees @ .050. This cam should stop making power around 5500 RPM, and on the dyno I peaked @ 5800. I dunno, It would really suck to spend a day swapping my cam and not go any faster.
