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 - stock Pontiac Super Duty 421v8/405hp vs stock Chevy 409v8/409hp on DYNO
WATCH THE VID TO SEE HOW CLOSE THEY Dyno TO THEIR FACTORY
405hp/409hp ratings. Growing up.....Pontiac/Oldsmobile old timers/EXPERTS
who taught me most of what I know, often told me Chevy rated their horsepower in a more
optimistic way than say Oldsmobile or Pontiac. I've even heard Pontiac
rated/tested their engines in a 100 degree room, compared to Chevy in a 60
degree room. These Dyno results seem to reflect
that some of what I heard was true. Both of these engines are great, but
the results do seem to show that Pontiac was not rating their horsepower worrying if it
would cause "songs to be written" about their engines .... like the great
song "She's real fine my 409"--(Chevy).

A short video describing the modifications done to the 65,000 original mile
Pontiac 350 engine in my 1975 Formula. Using heads, cam, pushrods, rocker
arms and an intake that I had laying around, this Pontiac 350 developed 353
horsepower and 385
lbs/ft of Torque, for less than $500.00 invested.

Performance for insight on building Splitter's street / strip / road course
