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.

Ford FE 352 First start after rebuild.
Me and my dad built this engine, but mostly me, it has stock bore, just
honed, stock crank, just polished, new rings, new gaskets, new bearings new
oil pump, stock flattop pistons with new wrist pins, new 390 cam, new
lifters, new seals, new water pump, new fuel pump, edelbrock performer 390
intake, edelbrock 750 cfm manual choke carb, hardened valve seats, new
keepers, new clutch and pres. plate, new starter, clark 265 5 speed
transmission, MSD ready to run Distributor, MSD plug wires that need to be
shortened, Autolite plugs, MSD Blaster coil.
The engine had low miles on it when I rebuilt it but it had been sitting
awhile. Originally was in a 1966 Ford Galaxy with a automatic. I took a 330
M/D out of a 66 Ford B700 School bus and took the bellhousing, flywheel,
and trans for my engine. It was going to go in my 1947 Ford truck, but then
I got a 43 Ford truck with a good running flathead 6 in it and decided to
just keep the flathead. Don't quite yet know what to do with this engine

Pontiac Banshee A Longer Look
The Banshee was a vision for what the Firebird could become. Of course,
this concept car could never be built exactly, too low on the road and it
wouldn't pass the safety and crash tests, but it was exciting. It
demonstrated that the problem with GM cars didn't sit on the designers'
shoulders. They were more than capable of dreaming up engaging and fun
vehicles that would set imaginations on fire.
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 - stock Pontiac Super Duty 421v8/405hp vs stock Chevy 409v8/409hp on DYNO
WATCH THE VID TO SEE HOW CLOSE THEY Dyno TO THEIR FACTORY
405hp/409hp ratings. Growing up.....Pontiac/Oldsmobile old timers/EXPERTS
who taught me most of what I know, often told me Chevy rated their horsepower in a more
optimistic way than say Oldsmobile or Pontiac. I've even heard Pontiac
rated/tested their engines in a 100 degree room, compared to Chevy in a 60
degree room. These Dyno results seem to reflect
that some of what I heard was true. Both of these engines are great, but
the results do seem to show that Pontiac was not rating their horsepower worrying if it
would cause "songs to be written" about their engines .... like the great
song "She's real fine my 409"--(Chevy).

roughly 99% of straight pipe flow rates and provide a great muscle car
sound without interior drone or resonance problems. These mufflers are

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.
