That '70 1/2 Trans Am is awesome. IMO a nicer design overall to the Camaro. They may have performed near equal, but the Trans Am looked more badass.
Fantastic pics. Thanks.
My 1974 SD 455 Trans Am is good for around 12.0 flat in the quarter 115MPH trap speeds. Its set up the way Pontiac engineers would have wanted it with a Nunzi style Ram Air IV cam, small stall speed, re-jetted carburetor 3.42 rear axle. THM 400. Just love it. Still own itNot very fast by today's standards but, Colossal Burnouts!
Actually quick enough. I own a 1974 SD 455 TranAm THM 400 3.42 rear axle..good for 115mph trap speeds in the very low 12's. It is set up the way Pontiac engineers envisioned it with a Nunzi style Ram Air IV cam, re jetted carburetor, small stall speed, upgraded Ross Pistons. They would hold their own against LS6 cars, most hemi's and whatever else. Bone stock they were good for mid 13's. The horsepower very underrated but remember too, that they were quoting net horsepower. Gross stock HP around 370.Not very fast by today's standards but, Colossal Burnouts!
You just are plain wrong, or ignorant. Not sure which. Now if you are speaking of the "regular" 455, I agree with you, those were just station wagon engines. Ugly, eye of the beholder. Automakers had to scramble to to achieve a 5 MPH bumpers for satisfy regulators. I think they are beutiful and a one year body style only!
Not sure what to make of your post. It reads like you were replying to someone else’s, not the one you quoted (mine … #20).
I had just posted a pic of my college roommate’s ‘70 1/2 T/A. I said nothing about engine or performance. (As it happens, he had blown the original 400 but lucked out with a George DeLorean built 455 w/ all SD parts.)
The Firebirds and Camaros were mid-years because a strike had delayed production - IIRC. Note the nose decal is missing. He had bent the car (with me riding shotgun) just weeks before a track day. Somehow got it together in time. This pic was taken on the way back from Texas World Speedway (RIP) after the event.
Also unsure of why I might have been accused of ignorance (we don’t know each other); but years ago most of my kids would surely have agreed with you.
He must have quoted the wrong post, @oldmachguy.

Disagree... split bumper Camaro all day and 2x on Sunday!
