Not more than the Hemi they mention (425 if I remember). And I think the Chevy had an even bigger HP engine.

“Not more than the Hemi they mention (425 if I remember)”

I was told by a Mopar expert that the 425 hp out of 426 cu in rating was a joke. For some reason Chrysler wanted to keep the motor rated below 1 hp per cu in. It may have been insurance. The actual hp was much higher.

HP ratings have changed since then. 420 now was like 450 or 460 then

The numbers were WAY understated in many instances to please the insurance companies ... a street hemi was over 500 easy... the only Chevy that came close was the ZL-1 ... the strongest “muscle car era” small block was the Ford 351-C at 290 hp NET ,, made more than the 375hp GROSS Fuelie Corvette 327.
