Smile Muscle car motors HP & TQ
Watched American Muscle Car on the Speed channel this morning. The show took 5 original stock muscle area motor and dyno'ed them. They want to see how close factory HP ratings were to the real thing. I had a pen and paper, so here is some of my notes

409 Chev 409 HP test 406.5 hp @ 6,000 & 430 tq

427 FE 425 HP test 637 hp @ 6,500 & 554 tq

421 Pontiac 405 HP test 488 hp & 470 tq

426 Hemi test 820 hp & 689 tq

427 Rat L88 425 HP test 527 hp @ 6,000 & 501 tq @ 5,000

I hope my notes are correct. Very interesting show and it looked like they tried to show just the true HP of each engine. They closed the show by saying there were a lot more muscle motors and they would do another show to include more motors.
If some of you guys saw this show and have more numbers to add, please do.
