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.

550 torque @ 5800rpm
535hp @ 4000rpm
For those of you paying attention and noticed the numbers aren't the same
on the screenshot, its because we made another few runs, but didn't tape
them. We'll upload a pic soon.

71 455 HO Trans Am at the Dyno Shop
This is a 455 HO 4spd 1971 Trans Am that is in the last stages of a
complete restoration. We have taken it to the Dyno shop to dial in the numbers
matching motor after we did a complete rebuild on it for our client.
Pulled around 415 HP to the flywheel. www.RESTOREaMUSCLECAR.com
1965 Pontiac Tempest Wagon
Here's a 65 Tempest wagon in amazing shape! It has a numbers matching 326ci
V8 and a fresh 200-R4 4 speed automatic transmission! The engine has 18,000
miles on it since the rebuild so everything is in tip top condition! The
car only has 92,000 original miles. The paint is in fantastic shape,
especially considering it's 47 years old! It has restored 7x14 Rally II
wheels with BFG tires, a new power brake system, new power steering pump,
new power rear window motor, and tons of other new parts. The entire car
has been gone through and is entirely mechanically sound. The interior has
been restored using much of the original vinyl, has new carpet, a new
headliner, new arm rests, and the AM radio works! Other options include
front and rear sway bars, new 2 1/2 inch Exhaust and new splitters, new windshield and
heater core, and way too much to list! Comes with a 4 barrel setup as well!
This thing is ready for a road trip!
1974 Trans Am Super Duty 455 Four-Speed FUN
This is a very rare 1974 Pontiac Trans Am Super Duty. Less than 1,000 of
this 455-powered, specially built monsters were produced from 73-74. Today
they command ever increasing prices approaching six figures.
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!!!
1964 Pontiac Tempest 455 V8 High Performance Muscle Car
I thought you'd like a look at this very clean 1964 Pontiac Tempest. This
is a great example of Pontiac muscle that has been frame off restored and
modified just enough to make it exciting! It's decked out in white paint
with a red vinyl interior and factory steel wheels with correct hubcaps for
a classic Pontiac look, but wait until you open up the hood. There you will
find a completely rebuilt Pontiac 455 CID V8 complete with roller rockers,
HO Exhaust manifolds, Edelbrock 4
barrel carburetor, Edelbrock Pontiac Torker II aluminum intake, Mallory Hy
Fire electronic ignition, and a 4 core radiator. The transmission is a
rebuilt turbo 350 Automatic with a 2500
stall, and all of this is run through a Ford 9" posi rear end with 3.73
gears. There's plenty of power to spare in this beast! Other options
include hub caps, red line radial tires, factory style wheels, power
steering, seat belts, bucket seats, and an in dash tachometer. Thanks for
taking a look!

PONTIAC GTO Judge (1971 455cid, the differences basic supertuning can make)
Those who know me well, know that I always beat "SUPERTUNING"
"SUPERTUNING" "SUPERTUNING" into the ground. This video shows the
difference minor tuning can do (This is minor because a 1971 GTO's fuel/ign
calibrations are already geared for performance, so there's not as much
improvement you can make like you'd be able to on say - a late 70s
smogger). But on larger scales, HUGE differences can be made, as much
difference as adding performance parts alone. The more the car is severely
out of tune/adjust------which happens more with the more mods you make,
then the more you'll gain by supertuning it. There's another vid on YT
where an Olds 455 was built with performance parts to be totally streetable
but achieve 1hp per cubic inch. After they got the recipe of perfect parts
all together they were disappointed when she only Dynoed at 320hp. But luckily
they did not give up! After the proper ign-curve/timing & carb adjusts were
made, the engine jumped from 320 up to 455hp!! No doubt all the new
cam/intake/head mods put the old fuel/spark adjustments badly out of
calibration for the NEW BREATHING ABILITY. Also with things like dual quads
(especially to engines not originally equipped wit them), your adjustments
are most likely going to be way off and need calibration even more. There's
lots of dual quad cars out there not running well for this reason, however
the few that have been calibrated perfectly (EVERY adjustment set for the
best "stop watch" time, etc) truly do run like a bat out of hell!
