First start up of my bored out 400 from 1979 trans am. Now a 406 with comp cams extreme energy hydraulic cam and lifters, roller timing chain and roller rockers. Lightened and balanced Scat crank. Ignition upgraded to MSD HEI with Accel 8.8 mm sprial core wires. 6X-4 heads ported and port matched to ported factory dual plane intake manifold. Factory 750 CFM Quadrajet reworked by Cliff Ruggles performance.

Quadrajet air leak fix and warped air horn repair tutorial.
How to identify a Quadrajet with a warped air horn without diss assembly or
running it on a car. These tips would have saved me time and money which is
why I made this video. I also discus how to repair a warped air horn and
prevent your air horn from warping in the first place. If you have a
whistling noise just off idle then you got some work to do. You will never
get your engine tuned right, your cold start performing or decent fuel
economy unless your four barrel carburetor is just right. Special thanks to
Cliff Ruggles for his book Rochester Quadrajet carburetors and to my
brother Adrian who spent hours on tuning and fitting.
See this video for description of the technique I used to straighten a
warped air horn.
here is a technique for re-bushing the throttle shaft without drilling.
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 350 - 350 Horsepower For Less Than $500.00
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.

Nothing beats the satisfaction of chasing down and pulling old cars from
their resting spots. There is a thrill in the hunt, and a joy in
discovering a car that nobody else knows about. These are the cars that
have been parked for whatever unknown reason ; a blown tranny, discarded in
disgust, set aside for later. Many cars are sentenced to a particular spot
with no release date in mind. They all have a story to tell, and one has to
wonder who fell in love with the vehicle first and plunked down all their
hard earned cash on the beast.
Cracking open the door is like entering a ancient tomb, with the rusty
hinges announcing your arrival. Every old car has it's own unique smell,
some brands even possessing their own odors.
Pop the hood next. Engine bays come in 3 types, complete, empty, and
partially disassembled. A complete bay is the ultimate goal, for that means
there is a small chance that the car might still run. An empty bay puts the
car towards parts-car status, or full swap/update for sure. A half complete
mill is the worst situation possible. One must play detective and figure
out what went wrong and where all the missing parts currently reside.
Pop the trunk, and it's time to go treasure hunting. The trunk can hold
anything from missing parts and nos trim, to possums and many other
shocking items forgotten over time.
The adventures of moving a car that has not moved in decades is immediately
present. Brakes stick, bearings freeze, tires are square and downright
ignorant, and every immobile wreck instantly gains 1 ton over its
still-mobile twin. Might be the 1800 pounds of old concrete in the trunk,
the one the owner conveniently "lost" the keys for. Many times there is
things in the way that were not present when the car was parked 45 years
Naturally, not all these cars go into the garage and come out show queens.
Some get fixed, few get finished, and most get slated for parts service.
The ones that do not meet one persons standards get pawned off on fresh
hunters with less money and more ambition. Maybe the car will help out to
get another twin out of the weeds also and back on the road. But one thing
is for certain, once the derelict wreck is loaded, the standard question
always asked is "Do you know of any more old cars around here?"
