Sehr Performance Machine / Randi's 400 Pontiac
Randi came to us with a 400 Pontiac project for his 1968 Firebird. He didn't want to go crazy on the build but he wanted something that would give him performance that is better than original. With that goal in mind Scott did some custom porting on his heads, upgraded his valve train and went with a Custom COMP cam and lifters and aluminum roller rockers. We maintained his complete original rotating assembly but had to re-balance his crankshaft, it had been poorly balanced sometime in the past and was out by 127 grams on one end and 181 grams on the other. A single plane intake with a 780 Quick Fuel carb got it breathing and the fire is lit with a Flamethrower ignition package. Custom cut and fitted 8mm plug wires are standard equipment here at Sehr. Headman custom coated headers will be added at installation time. The results were a satisfying 543.5 Hp @ 5500rpm and torque reading of 519.8 @ 5400rpm. Corrected to sea level the numbers are 577 Hp and 551 Tq with nearly 400 lb of torque at 3500rpm.
