I took my car to the dyno today and really glad I did. On the first pull the air/fuel was like 15.8 way to lean, took the carb apart to change jets and found out they were only 71 in front and 73 in the rear. We change them to 76 front and 78 rear the air/fuel is now 12.95 which is a little rich but the motor pick-up 25hp to the rear wheels. This carb is a 950cfm Holley.
So now on motor it makes 392.31 rwhp and 331.58 torque.
Did’nt have the NOS bottle in the car, but when we dyno it again I hope to have the fogger hooked up with a 300shot.
