[Super73]

Marv,

I am planning on sticking the 251/266 in and dynoing before going to the track on 6/20. I will try it at the track. Then I plan on sticking my old 254/260 back in for another round of dynos and a track outing in july. So by August I will have the best all around cam of the 3 I have in the motor fir the remainder of the year.

Then I have aug-oct to try and muster an 8.xx out of the truck.


I know the 9" ribs power but the rear end though should not have had an effect on peak hp rpm which the new cam seemed to have peaked a tad earlier.
