Beautiful! I can still hear the low rumble of those when they were at idle, let alone when the pedal was down

I too enjoy that smell (and sound) of an under muffled loping usually carburated V8 at low RPM running rich. Just makes me think how efficient it must be at freeway speed or more at 4k-5k RPM and those 4.10’s are screaming for mercy

OP. Nice TA! I can smell your car idling from here and I love it.

Even as a little kid I liked the smell of diesel exhaust. My little home town was on US 40, and had a bus stop for Greyhound buses. I loved their aroma. Those big, sleek buses seemed so exotic. Yeah, I know I’m an outlier, but I am what I am.

Lets just say that I have a connection for 100 LL. This tank was a concoction of 110 racing gas, mixed with the 100 LL and some 93 premium. In my youth when I built this engine I never gave it a second thought making the compression 13:1.

13:1...

Please share the Engine/Drivetrain specs. Pontiac nut here w/ a '74 Formula...



Launch View...

And “TRANS AM” is short for Trans AMERICAN – gotta love that. No other country in the world ever made anything like American muscle cars.

What likely ruined the olfactory (probably brain cells as well) was riding our bikes behind the mosquito sprayer trucks here in Miami back in the very early days

.090 over bored 428 Pontiac. Right at 445 cid. Cam is a 601 lift 301 duration, compression is right at 13:1 as it has a set of decked ported and polished Ram Air 1 heads. Intake is a vintage Offenhauser 360 with a 750cfm Edelbrock carb. Aluminum roller rockers and solid lifters. Hooked to a race built Turbo 400 tranny with a 3500 stall torque converter and a 3:23 rear end.


And running first start up after coming out of storage.

Post it up, as long as it's a Buick from when they made cars for younger people.

I owned a '77 TA for many years......put 143K miles on it. I sold it to my barber. One could "recalibrate" those smog engines and really wake them up. I still own a couple of cars familiar with 100LL.
