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.
Big Burnouts: 1964 Pontiac Catalina Safari - /BIG MUSCLE
If you haven't figured it out by now, we love wagons on this show. To some
they're a misunderstood breed, but to those in the know, they're amazing.
Not only were the wagons of yesteryear known for their styling, but their
capacity to haul as much cargo as a modern day pickup. This 1964 Pontiac
Catalina Safari started off life as a Police Wagon, but was transformed by
its owner into the kick-ass, tire-shredding monster you see here. With a
Nelson Racing Engines 468 cid big-block under the hood, some updated
suspension bits and a killer look, this big green machine is
outside-the-box styling at its best.

1967 Pontiac Firebird 20 Year Cold Start
We work on starting my new 67 Firebird after it has been sitting for 20
years untouched in Wasilla, Alaska. The tags expired in 1989. It has the
original Overhead Cam Inline Six Engine. Before starting it we put oil down
the cylinders, primed the oil system, changed the oil and replaced the Cap,
Rotor, Plugs, and Points. A Complete restoration is planned for the
Custom 1972 Pontiac Firebird - V8 sound!
Jamboolio records a fully restored 1972 Pontiac Firebird with the 350 cid
5.7L V8 engine and a stunning new paint job.
The monstrous hood scoops and huge air vents added to the all black
exterior makes it a very bad-ass looking muscle car beast! The Exhaust sound is pretty awesome too! Enjoy.
