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.

Sehr Performance Machine / Ryan's 350 Pontiac
Ryan dropped off his 350 Pontiac long block along with a set of 400 Pontiac
Ram Air cylinder heads, an Edelbrock intake and his Holley carb. He wanted
us to put it together for his '69 Firebird. His engine came to us with
blow-by issues from a broken piston. First off the cylinders had to be
relieved to clear the valves on the Ram Air heads. The heads were milled
to reduce chamber size and valve to block clearance was checked one more
time. All of his parts were inspected and magnafluxed to be sure we were
starting off with serviceable parts and the clearances were brought back to
low side of factory tolerances, a new custom COMP cam and a distributor
curve kit were added along with some other touches, the engine was painted
Pontiac Blue and bolted to our Dyno. Ryan is very happy with
the end results and is looking forward to getting it back in his car and
having some fun with it.

Big Burnouts: 1964 Pontiac Catalina Safari - /BIG MUSCLE
If you haven't figured it out by now, we love wagons on this show. To some
they're a misunderstood breed, but to those in the know, they're amazing.
Not only were the wagons of yesteryear known for their styling, but their
capacity to haul as much cargo as a modern day pickup. This 1964 Pontiac
Catalina Safari started off life as a Police Wagon, but was transformed by
its owner into the kick-ass, tire-shredding monster you see here. With a
Nelson Racing Engines 468 cid big-block under the hood, some updated
suspension bits and a killer look, this big green machine is
outside-the-box styling at its best.

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...

We have really enjoyed the relationship that has developed during the
coarse of this build. It's fun to work with someone who gets excited about
what their doing.
With a lot of custom head work, a custom COMP roller camshaft, and some
other trick parts and machine work we were able to develop 474 lbs of
torque and 503 horsepower.
Sehr Performance Machine / Marvin's 460 Ford
Marvin brought his engine to us to 'hop it up a bit' but still keep it
legal for class that he pulls in and keep it reliable as well. Starting in
the heads, we boiled them out cleaned and magnafluxed them before shot
blasting. Next was a clean mill just to get things straight. A 5-angle
valve job, fitting the guides and installing new Viton seals were next in
the order of business.
While we were at it we cleaned and magged his block and shot blasted the
rods and block. His mains were out of wack and his crankshaft was bent so
we did a line bore on the mains and fixed him up with a new crankshaft.
Next in line was a clean mill on the deck surfaces and lifter bore grooves.
Every part that went into Marvin's Ford was completely checked and those
that didn't pass muster were replaced with quality new parts. No headers
allowed in Marvin's class so we ran his iron Exhaust.
