NHRA Horsepower Ratings for the 273

Mike,

The 273/235 HP was lowered to 220 HP, then lowered again.

Now it is rated at 210 HP.

I would have to agree, Mopar did overate the 273 Commando.

A 2940 lb. A-Body should have had a Wt/Hp Factor of 14.00 with a 210 HP rating.

Those cars would have done a lot of damage back in the mid-late 60's and
early-70's in the NHRA Class (14.00 - 14.99 Wt/Hp).
