I just got my new engine installed. Its a 306 with twisted wedge heads, trick flow street intake, forged pistons, 9.8:1 comp, JBA headers, 75 mm TB and 75 mm Mass-air, 30# injectors, 190lph fuel pump. The combination is putting out 425 HP and 442 lbs of torque. I got it installed and ran it for 200 miles. It started running rough, idle was bad and cold start was terrible. My problem was the fuel pressure: it was running at 22 psi at idle and 28 at about 2000rpm. I drove it like that for over 200 miles! Is there a chance that anything is screwed up? How serious or how worried should i be about my new engine!!!?? Thanks
