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...

super car? No! The kings of restoration are restoring a 1968 Pontiac GTO

turning it back into the Gran Turismo Omologato.
GTO First Start Up
Having a conversation with Darrel Arvizo, AKA "Slo-Moe", about his sweet
GTO build and NOT getting a straight answer out of him on anything. I'm

LOL. Anyway, this is what I do know.... The chassis was built by Rob
Lindsay at R.J. Fabrication, engine build by Rock & Roll Engineering and
NHRA Super Stock Indy winner Bruce Fulper, body work done by Tony "Cricket
Fingers" Griffin, C&R Radiator, APS-Racing carb spacer, CCP control arms,
MSD Ignition and a lot of hard work by Slo Moe. Hurry up and Git-R-Done!
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.

This time, we're test-assembling the brackets and parts on the engine, and
