I'm sorry but it's been way too long for me to remember the torque curves for TRACO's T/A engines (or any for that matter), but 475-490 HP was a good number for the Chevys, on TRACO's dyno. We did occasionally rebuild engines originally built by some of the competition, and their Dyno HP was no better than ours, usually a little worse, some quite a bit worse. The AMC T/A engines were a little better, around 510-520 on the Dyno.
I know that some would question it, but TRACO engines were built the same for all customers. The only exceptions were special items that some customer got hold of, but all in all, Penske's engines from TRACO were duplicates of his competitors, those built by TRACO.
Penske did have some "pull" with the Chevy factory for Aluminum blocks and heads, not for T/A racing.
For the T/A series, Penske ran 2 cars, each with 3 engines; 1 in the car, 1 on the truck as backup and 1 being rebuilt at the shop, this was the same for both Camero and Javlin.
As I mentioned in a previous post, I don't personally have any photos, looking back now I wish I had, but I was young and dumb, with never a thought of the faaaaaaar future when I might actually enjoy reminiscing.
