I installed my level 3 Quadrajet today on a 1" open spacer and let me tell you it was amazing. It started right up once it filled with fuel. After a few minutes it warmed up and idled fine, about one full turn of the idle screw to bring it down a few hundred rpms and I was ready for a test drive. The drivability is outstanding! At part throttle at 55mph I had to keep lifting my foot off the throttle to be sure I wasn't just idling along. Nice! My old carb (edelbrock 750) would start to lose power above 4000rpms, this pulls hard to 5000rpms and more I'm sure if I let it. Thanks Mark! I am now only a battery hold down, a helmet, and some time away from my first run down the track. Cliff. My mistake. Quadrajet power!!!
Cliff... I sent Mark at Quadrajet power a few carbs last year and in return, he rebuilt a few for me. AWESOME, turn-key rebuild! This guy is a whizz! Wheelz, Tampa Bay
