Problem...

I have a similar set up in my dart except it's a 360. I run 72 and 83 jets w/a 50cc pump in the rear. Front acc pump 30cc. When I'm racing I have a 38 squirter in the front. 34 rear and orange pump cam. I also adjust the front pump where there is play at the pump arm at idle, that gives you a bigger shot when you dump it... I leave on my converter 15-1800. Timing 18-20* @ idle 36* @ 2400. I'd replace the fuel pump with an aftermarket one. I run the carter 6270 or 6290. It's the street/race 7 psi pump.
