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.

Pontiac Banshee A Longer Look
The Banshee was a vision for what the Firebird could become. Of course, this concept car could never be built exactly, too low on the road and it wouldn't pass the safety and crash tests, but it was exciting. It demonstrated that the problem with GM cars didn't sit on the designers' shoulders. They were more than capable of dreaming up engaging and fun vehicles that would set imaginations on fire.





1970 Pontiac Grand Prix 400 Model J Engine Bog
My 1970 Pontiac Grand Prix runs, but hesitates (bogs) on quick acceleration. When accelerating slowly this problem does not occur, only when doing so quickly. It has new high quality Bosch spark plugs, and a replacement carburetor (Rochester 4 barrel quadrajet), everything else is stock. It is running on premium fuel with lead substitute. If anyone knows what I can do to fix the bog, please comment or message me, thanks.

1967 Tempest new camshaft Ultra Dyne 220/226 @ .050 in Pontiac 400
Traded my friend Robert for this camshaft. Came already broken in with a matched set of lifters. I swapped it out over the last month or so. I still have to install the temp gauge in the car, so I am not running it that long yet. Put around 2 miles on it. PULLS!!!! Hard!!! I have to find the coil bind on the springs. might have just increased redline!!!

1956 Pontiac Star Chief Low Mileage Survivor 317 V8 - Gateway Classic Cars
I thought you'd like a look at this very original 1956 Pontiac Star Chief. This amazing survivor has only 74,xxx original miles on the odometer. It's powered by the factory 317 V8, backed by an automatic trans. It has all original interior and even the factory Air Conditioning. You won't find too many out there like this anymore. It has a cool patina to it, that can only be built up over decades of use. If it were me, I would leave this car as it is and just have fun cruising it. I hope you find it interesting....thanks for watching!
