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.

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.

PONTIAC - "The Super Duty Story" Part 1 of 3
Pontiac had an SD engine program in the late 50s early 60s, and
later/briefly again in 1973/74 with the SD455. This video is regarding the
FIRST Super Duty program.---In only a few years time during the late 50s
early 60s, Pontiac MORE THAN DOUBLED their V8's horsepower output (described
in this video), while using/keeping the same V8 engine block they used thru
1955-81. Even though the same block was kept, from 1955-62 the cubic inch
displacement grew much larger than the initial 287 cuber it started as in
1955. It grew to a 317 347 370 389 and finally a 421 cuber in 1962. It
eventually maxed out at 455 cubes in 1970. By 1970 ALL the other GM
divisions were producing engines at 454 or 455 cubes (500 for Cadillac).
PONTIAC WAS THE ONLY DIVISION still using the same block they used in the
1950s on engines that had a much smaller displacement -- 287 cubes. The
1955 287 displacement would remain the smallest displacement ever used in
the Pontiac V8 block all the way until 1980/81 when a 265V8 was produced.
Since less durability was required for the smaller displacement, the block
was decked/butchered/lightened on the 265/301v8s of 1980/81. Prior to 1980
the block had never been decked/butchered/lightened. The 1980/81 265/301v8
blocks were about 200 pounds lighter than the 1955-79 blocks, and only 25
pounds heavier than a Buick 231V6.
BEST of Muscle Cars ( CRASH and FAIL ) pure sound EPIC
