Car pics too cool not to share

I sent some off recently and it took 5-6 weeks to get results, so just expect something similar. Normally it only takes around 2 weeks for results.
I'd love to see this one with the rear wheel opening radiused to match the front, then get the back end down a little.
Things can be swapped around if they fit, but an easy way to distinguish a 348 from 409 at a glance is dipstick location. Driver side = 348, passenger = 409 (I don't know if 348 and 409 oil pans are interchangeable). Beyond that, factory 3x2 setups were only available on 348, 2x4 only on 409.
1963 421SD "Swiss Cheese" Catalina, originally owned and raced by Mickey Thompson. This was #3 of 14 produced by Pontiac for their drag racing program. This one has many factory lightweight aluminum parts including the hood, inner and outer fenders, core support, front bumper, brackets, and rear bumper. Other lightweight parts included an aluminum intake manifold, aluminum differential carrier, aluminum headers, and plexiglass windows. Out back were a set of 4.30 gears with Safe-T-Track. To further reduce weight Pontiac drilled large holes in the frame. This would prove to be the pinnacle of Pontiac's weight reduction program. On January 24th, 1963, Pontiac issued a memo that their 389/421 Super Duty engines were cancelled, effectively ending their factory backed racing program.
You sure don't see a lot of '57 Pontiac gassers, that's for sure. I had a '57 Starchief that I bought back in the '80s. They're a fairly substantial car. Don't know if they're actually heavier than the Chevy, but they feel like it. Don't feel anywhere near as heavy as the Buick or Olds of the same year, however.
Bummer ! , Aftermarket cooler , plug trans cooler in radiator , change ATF several times , see what happens short term. It might surprise all of us with success.
727 's are Turbo - 400 kind of tough !!!!
Yes they are. Way back in the day they were known as one of the toughest auto trans made. And a pretty simple transmission to rebuild as I remember it. We rebuilt both a Turbo 400 & a TF 727 when I took a automatic trans course.
