Not more than the Hemi they mention (425 if I remember). And I think the Chevy had an even bigger HP engine.
*********************
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.
The 351C. Struck more fear into more BBC owners than about anything.
And oh what a sound.
?.. over 500 easy ...
