Chevy, Olds, Pontiac and Buick V8 engines are not the same!
Evidently a segment of the automotive enthusiast population does not believe that the four main GM divisions had their own versions of a V8. In addition there may be people who simply never knew that fact.
In this video I show photos of a 350 cid engine from Buick, Oldsmobile, Pontiac and Chevrolet and highlight the differences in each. Buick and Pontiac V8 engines went out of production in 1980, Oldsmobile's in 1990 and of course the Chevy versions lasted a lot longer because they were cheaper to produce and easier to smog/mpg certify.
I challenge anyone to video themselves removing a Chevy SBC head and then installing it on a Pontiac, Olds or Buick engine.
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).
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.
9 Second Buick GSX Stage2 GS Stage1 9.51 @ 140
We originally built this car with Frank Urbinati back in 1996.It debuted at
the GS Nationals where it won the GS Pro Street class races. It was also
the 1st GS Pro Street class car to break into the 9's at the time.Thanks to
Frank this project came to life. Fast forward to 2010 and the car has been
taken over by Bob Ortolani,the car still looks great and Bob decided to
bring it up another level. We were happy to have the car come back to our
shop and to have the opportunity to work with Bob and put together the new
powerplant. The video shows the results of our 1st day out to tune the
engine. The 1st two passes were shakedowns to check fuel/oil pressures and
get a feel for the new combo. By the 3rd run we had posted a 9.62 @ 138
hitting the 7100rpm rev limiter chip! The 4th run was a 9.52 @ 140. On the
5th run it went 9.51 @ 140.65! After a good cool down and a timing
adjustment we were ready to try for a 9.40 run, launching right off idle
the car gave us a nice big unexpected wheelie! The wheelie sure lookes cool
but we know we can go quicker with a little more suspension work to
straighten out the launch and try to keep the front down. We're sure it'll
go into the 9.40's yet and maybe even 30's after everything is worked out.
409 Chevy Engine Build -- Part 2
This Chevrolet 409 build is meant to be a wolf in sheep's clothing. We
stroked the rotating assembly to up the displacement from 409 to 440 cubic
inches and then replaced the stock heads with much more capable units from
Edelbrock--but painted them to disguise the modern aluminum castings. The
end result is 505 horsepower and 507 ft/lbs of

The Pontiac Super Duty 455 was unique in several ways. This video will give
a bit of insight into what makes it special. The background music is

duration at 222 degrees on both the intake and the Exhaust.
Information about Oldsmobile V8 engines
In this video I talk about the "late" Oldsmobile V8 and offer tips on how
to identify them by number.
"Late" in this instance means 1964-1990. Early('49-64) Olds engines are an
entirely different block, etc.
Sometimes my info gets a bit twisted when it stays inside my head for a
while, so a correction is that '77-80 heads are 3A, not 4A. 4A heads are
Also, to clarify and avoid confusion, this...7 A is a 350 head, this...7A
is a later 307 head. You can also tell the difference easily by the ports.
Late 307 and 260 ports are half the size of any other versions.
Trivia: The Olds 403 was used in 1977-79 Pontiac Trans-Am's, but not all of
Of note...the engine in the video is painted the incorrect shade of gold,
which appears to be the Krylon generic gold. The proper shade is slightly
darker and less "glitzy"
