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.

Engine has Holley 3130/750 now and different timing set up. Made huge
difference. I could never get the Edelbrock carb to work right. And yes
the Mr Gasket header gasket on the driver side was leaking just 40 minutes
after break in.
Chevy, Olds, Pontiac and Buick V8 engines are not the same!
Evidently a segment of the automotive enthusiast population does not
believe that the four main GM divisions had their own versions of a V8. In
addition there may be people who simply never knew that fact.
In this video I show photos of a 350 cid engine from Buick, Oldsmobile,
Pontiac and Chevrolet and highlight the differences in each. Buick and
Pontiac V8 engines went out of production in 1980, Oldsmobile's in 1990 and
of course the Chevy versions lasted a lot longer because they were cheaper
to produce and easier to smog/mpg certify.
I challenge anyone to video themselves removing a Chevy SBC head and then
installing it on a Pontiac, Olds or Buick engine.

1968 Pontiac Firebird vs 2010 Lingenfelter Trans Am - Generation Gap: Firebirds
Cast your vote here:
In this episode of Generation Gap the guys compare Firebirds: old vs. new.
Davin brought a classic 1968 Pontiac Firebird equipped with a 350-CID V-8
boasting 320 hp. Matt, on the other hand, had a bit of a trick up his
sleeve bringing a 2010 Lingenfelter Performance Engineering Trans Am
modified to the nines to look and perform like a modern Firebird. Its 455
CID and 655 hp are some impressive numbers, but how will it be on the road?
Generation Gap appears every other Tuesday on the Motor Trend youtube
