GN7, I will stick with my guess... I'm assuming Uncle Daves CR isnt more than 11:1 if he is getting by on pump premium... Uncle have has a decent spec. hydraulic roller and Chevelle has a nice smallish solid roller...
5% more HP would be 25 +/- and Daves cam/heads/carb set up is done by 5600RPM...
I wager that Chevelles cam/heads are done by maybe 6300RPM +/- 100 RPM for his peak HP... With the same or maybe less torque...
Uncle Daves combo makes 510 TQ at 4400RPM
Hope all is well my friend...
NOTE, Chevelle: I don't mean "smallish" in a bad way at all and I would prolly pick something with the same manners if I was going to drop the $$$ for a solid roller...
