HI what revs will this motor be making peak hp at, the combo is as follows
ZZ454 9.6 COMP comp hyd roller cam xr282hr 230/236@50 0.530/0.540 lift lobe sep 110 degrees stock gmpp aluminum heads same as eddy heads 290cc
1.7 rockers beehive springs
Intake vic jnr carb 750dp holley with proform centre body
What revs should i be shifting at and what revs going over the line got told your need to be going over the line at peak power ,yet some guys say you want to be going over line at 500rpm more than peak power in valve bounce no good in hyd roller cam b/b chevys
Also got 150 shot spray i use ,hope this enough info
thanks

If you dont use Morel hyd lifters you wont even make it to the engines peak power, before you you have lift/spring valve float issues

I'm just off the top of my head thinking like 5500 rpm for peak hp or thereabouts at 230/236.

Uncorked, small tube headers.
