Any 70-73 is my favorite, but I like all of the second gen f-bodies, up to 79.

Not a Trans Am but as close as I can get!
That formula hood is way better than a T/A.

Re: Trans Ams

I wanted to see the performance specs. for 1969 through 1974 Trans AMs. Then thought to compare that to Z28s. Made a small project of it, please let me know if you see an error, I'll straighten it up. Unfortunately an image is too small to read, sorry

I'll paste the data here....

Car - Engines Available - Compression - Torque @ RPM - HP - 0-60 Time - Quarter Mile - Comments

1969 Trans Am Ram Air III and IV, 400, 4 bolt main - 10.5:1, and 10.75:1 - 430 @ 3400, and 430 @ 3700 - 330-345 - 5.4-6.5 - 13.7-14.2

1969 Z28 302, 4 bolt main - 11.0:1 - 290 @ 4200 - 290 - 7.4 - 14.8

1969 Camaro 427 - Yenko Camaro 427 - 4 bolt main - 11.0:1 - 460 @ 4000 - 430-450 - 5.4 -12.59 -"For comparison. 427s were options in Camaros, but not Z28s. 427 data is limited to the 1969 year, for this writing.

1970 Trans Am Ram Air III & IV 400, 4 bolt main - 10.5:1, and 10.75:1 - 430 @ 3400, and 430 @ 3700 - 335-345 - 5.4-5.6 - 13.9-14.9

1970 Z28 350 LT1, 4 bolt main - 11.0:1 - 370 @ 4000 - 360 - 5.3-5.8 - 13.9-14.2

1971 Trans Am 455 High Output, 4 bolt main - 8.4:1 - 480 @ 3600 -340-345 - 5.4-5.9 - 14.3

1971 Z28 350 LT1, 4 bolt main -9.0.1 - 360 @ 4000 - 330 - 6.6 -14.5

1972 Trans Am 455 High Output, 4 bolt main - 8.4:1 - 415 @ 3600 - 345 - 5.4-5.8 - 14.3

1972 Z28 350 LT1, 4 bolt main -9.0.1 - 280 @ 4000 -10 less HP than the 1971 Z28 - 6.5 - 15

1973 Trans Am 455, and 455 Super Duty (SD) 4 bolt main - 8.0:1 - 370 @ 3400, and 390 @ 3400 - 250, and 290-310 - 5.6 - 13.75-14.3 - 0-60, and Quarter Mile times are for the 455 SD.

1973 Z28 350 L82, 4 bolt main - 9.0:1 - 280 @ 4000 - 10 less HP than the 1972 Z28 - 6.7 - 15.2

1974 Trans Am 400, 455, and 455 Super Duty (SD) 4 bolt main - 8:0:1, and 8.4:1 - 330 @ 2800, 355 @ 2800, and 395 @ 3200 - 240, 250, and 290 - 7.5, and 5.8 - 15.8, and 13.75-14.3 0-60, and - Quarter Mile times are for the 400, and the 455 SD.

1974 Z28 350 L82, 4 bolt main - 9.0:1 - 280 @ 4000 - See 1973 Z28 - 7-7.8 - 15.5

I agree, but that particular hood is a complete cobbled up mess. One of the original design guys wanted the formula hood on the TA but upper manglement preferred the look of the shaker hood.

I have some HPP magazine that have articles that interviewed you dad!

Re: Trans Ams

While the formula hood is cool, I always preferred the shaker. After all, it worked very well for Mopar.

The formula is a sharp sharp car. I just prefer the TA by a little bit. Here's a 71.

Safe to assume Formula and TA performed equal or close enough for like drivetrains? Seems a Formula could be ordered without GM's best performance engines, perhaps even standard, not sure. TA and Z28 seem to have always got GM's best, short no sight of a 427.

Cool video, I thought shakers were vacuum operated anyhow. Hmm, maybe they shouldn't be not sure. https://youtu.be/kZ4g_XKia1I

Re: Trans Ams

69 T/A's will always be my favorite and my go to if I was looking for a Pontiac F body, but I have always had Camaro's (my current 68 was my first car) and have just liked the Camaro styling just a bit better. I am sucker for first gens even though Ive had more 4th gen F bodies over the years.

I did get to go through a massive car collection recently where there were quite a few trans am, even 4 of the 8 69 T/A convertibles built.

Re: Trans Ams

That's amazing, just eight built, wow - Brothers cornered four, not a bad spot to be in. Never heard of them. Apparently they made their fortune in the print bus. Distant relatives Richard Nixon. The 1969 ZL1 Camaro and plum crazy Hemi stand out for me.

I actually liked the 70-72 Formulas better than the T/A's.

Never heard that one, the most common story I have heard time and time again was their parents had nursing homes and they expanded that over the years.
