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.

Part1 1959 Pontiac 389 resurrection for "The Find" 1956 GMC 250 Dually
I HATE PRE-ROLL ADS! YouTube can't seem to get the code right. I've reset the defaults to NO PRE-ROLL ADS 3 times now. Sorry for the pre-rolls. I'm still working on it. Snagged a 1959 Pontiac 389 from an hour or so away. Pig in a poke, really, but they don't get any easier to find as time goes on. The 56 needs a heart transplant, and 389 cubes is the biggest direct bolt-in you can get your hands on! I don't know how many parts there will be. Just trying to get it edited and uploaded! Cubes... Gotta have cubes...





Engine rebuild part 1
This series is available on DVD Here is the link http://realfixesrealfast.com/realfixesrealfast.com/Repairs/Pages/Rebuilding _an_engine.html We are rebuilding a GM 350 5.7 engine. Now in this particular case we are also going to upgrade the engine to a 383 6.0 This is called building a "stroker" motor. In other words we are increasing the "stroke" of the engine which increased the torq & horsepower. If you are able & wanting to rebuild an engine, this video should give you a good overview of what to do. If you are having someone else build an engine for you, you will be able to see what's involved in the process

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 immediate future.
