USMC, I really appreciate your response and knowledge...here's a little more info to clarify:
I'm not sure the cam...mild to moderate. The tuner is just using the A9L computer and burning a Diablo chip. He didn't tell me the injector pulse or % they were at, but I saw the fuel curve on the dyno printout start to rise from 11.2:1 at about 5000 or 5100 RPMs and it kept rising gradually probably to about 14:1 at 5500 RPMs. At that point, the engine started conking out because I was losing spark, so I couldn't really see how much more fuel I was losing in the mixture.
Fuel pressure at full thottle is 45-47 psi....idle pressure is probably 39-40 psi. I am running a Paxton Novi-1000 with a 3.15" blower pulley and an 8" crank pulley.
When I did the 331 swap, I gapped all the plugs to .32-.33
Here's the two things I think I need:
(1) I just need an MSD (on the way) to fix the car losing it at 5500 RPMs and..
(2) I think I need to go with a "band-aid" set up by running an -8 AN fuel line from my T-Rex up to the 95 fuel rails.
Then have the tuner run the car. With the MSD controlling spark, he'll be able to rev the engine out further, and with that bigger fuel line, we'll find out if the pumps just can't handle it, or if I really just needed bigger fuel lines.
I can get
almost all the stuff I need for the fuel fix-it. Fittings: no problem, fuel filter: easy. My BIG problem, is finding an -8 AN size fuel line the right length from the front face of the fuel tank, under the car, all the way up to the fuel rails. And I also need that fuel line with the -8AN fittings on each end. I know I can probably take a string and mark off the length, but if you (or anyone) happen to know the length off-hand
, that would save me crawling around on my back and possibly miscalculating
