Muscle Car Of The Week Video #3: 1970 1/2 Pontiac Trans Am Ram Air IV
This week's Muscle Car Of The Week from The Brothers Collection is a
super-rare 1970 1/2 Pontiac Trans Am, complete with the Ram Air IV 400 cube
V8 and Muncie 4-speed transmission!
1970 marked the second generation for GM's F body platform, and the company
made substantial improvements to the car over the '67-'69 versions. The
1970 1/2 models were longer and more spacious inside, and generally drove
more comfortably than the earlier cars. 1970 also marked the peak in
performance Muscle Cars, and the 1970 1/2 Trans Am was one of the top
performers. The Pontiac Trans Am came loaded with numerous performance
add-ons, such as upgraded suspension, brakes, Exhaust, and distinctive styling.
This particular Polar White Trans Am is among the most sought-after of all,
as it features the 370 HP Ram Air IV V8 engine and a Muncie 4-speed
transmission. The Ram Air IV engine was assembled with very tight
tolerances from the factory, making it as close to a hand-built racing
engine as you could buy from GM. The RAIV package started with a 4-bolt
main block, forged crank and pistons, and a high performance oil pump, but
the big difference was in the top half of the engine. The Ram Air IV heads
boasted 67cc chambers, 2.11" swirl-polished intake valves and 1.77" Exhaust valves, and large round Exhaust ports. The .520" lift RAIV cam had a
long 308 degree intake / 320 degree Exhaust duration and pulled air through an
aluminum dual-plane intake manifold. These parts sounded more like they
were hand-picked by a race engine builder than a factory offering, but
that's what makes the RAIV so special. They only made 88 of these cars,
59 were manuals and the other 29 came with automatics. It's one of the
few cars where both transmissions were offered and the manual outsold the
auto. Watch the video to learn more about this Pontiac Historical
Society documented correct '70 1/2 and its unique details like the original
2-tone blue seat covers, 1-year only Rally II wheels, and distinctive

PONTIAC GTO Judge (1971 455cid, the differences basic supertuning can make)
Those who know me well, know that I always beat "SUPERTUNING"
"SUPERTUNING" "SUPERTUNING" into the ground. This video shows the
difference minor tuning can do (This is minor because a 1971 GTO's fuel/ign
calibrations are already geared for performance, so there's not as much
improvement you can make like you'd be able to on say - a late 70s
smogger). But on larger scales, HUGE differences can be made, as much
difference as adding performance parts alone. The more the car is severely
out of tune/adjust------which happens more with the more mods you make,
then the more you'll gain by supertuning it. There's another vid on YT
where an Olds 455 was built with performance parts to be totally streetable
but achieve 1hp per cubic inch. After they got the recipe of perfect parts
all together they were disappointed when she only Dynoed at 320hp. But luckily
they did not give up! After the proper ign-curve/timing & carb adjusts were
made, the engine jumped from 320 up to 455hp!! No doubt all the new
cam/intake/head mods put the old fuel/spark adjustments badly out of
calibration for the NEW BREATHING ABILITY. Also with things like dual quads
(especially to engines not originally equipped wit them), your adjustments
are most likely going to be way off and need calibration even more. There's
lots of dual quad cars out there not running well for this reason, however
the few that have been calibrated perfectly (EVERY adjustment set for the
best "stop watch" time, etc) truly do run like a bat out of hell!
F.A.S.T. 69 Ram Air IV GTO running 12's on G70's
This was my best run last year at Pittsburgh raceway, it ran a 12.82 with
1.80 60 foot time on G70's. This was my first year running this car and I
only had time to get used to launching the car correctly and shifting
differently. This run was done without using the clutch to shift, I also
tried speed shifting(not letting off the gas and bumping the clutch) and
did not pick up any time. The engine is a 69 428 built to RAIV specs with
an M-20 and 4.11 rear. I am going through the entire car and looking to
pick up more time this year.

Pontiac GTO on dyno
A Pontiac GTO on the Dyno. Sorry i don't have any
results, but it's a cool looking car and has a cool sound. I think it ended
up making alot less than the owner had expected, around 300 horsepower.
