Back in the Trans Am days, I think 475hp was about tops/ 2800 lbs min weight. 5.9 lb / hp
Nationwide is about 700 and 3400lbs. 4.9 lb / hp

Just for chuckles, here’s a bunch of yearly rulebooks for Trans Am.

thx... i got to know one of the pit guys on Penske's team back in the day and he showed me how they re-plumbed the air intake to the low pressure area in front of the windshield and painted the nub where the jack went so he wouldn't miss it(specially when hungover) and how they repositioned the oil filter inside the engine compartment so for quick filter changes and they even put the oil under compression so it literally blew the oil into the line through a quick disconnect fitting

those were the days
