Brule/Frieburger/Dulcich (whatever that show is called),did a test and found 20hp on a 500hp Chebbystroker, (4%),All same ratio. So maybe zero difference on a 500hp Mopar....lol
And that was at WOT and only at the top of the RPM range.
1.6 rockers would also only make any difference in the top end.
I agree to spend the money on a cam instead if any performance difference is to be the point of the upgrade.
