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.
Pontiac Night at S.A.R.
1968 LeMans powered by a 468 CID Pontiac engine. I'm out one night with
some changes to the engine.
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.
Sehr Performance Machine / Lane's 468 Pontiac.wmv
This is a 400 Pontiac stroked to 468. Lane had some work done elsewhere on
this engine in the past and was not happy with the outcome so he brought it
to Sehr to get it done right. Lane did it the right way, he has a really
good bottom end on it with Eagle stroker crank and Eagle full floating "H"
beam rods so he has plenty of reserve to build on.

pontiac 400 rebuild for my 1969 Firebird. It's bored and stroked to 468
cu. in. It has a crane cam 238/246 duration at 50, 114 separation.
Edlebrock performance Ram Air IV aluminum heads. Holley 770 carb. March
aluminum bilet pulleys. It Dyno'd out at 515 hp, 544 ft lbs
at 5700 rpm.
The body (1969 Firebird) and interior is currently being restored. Can't
wait to drop it back in and take it for a spin!
