" Grumpy??, Does,Anyone make an retrofit Hyd roller that makes good torque for a SBC in a heavy car with a std trans? "
sure they do but it would help a great deal to know more about the engine and drive train gearing and transmission its being matched with before any thought of selecting a cam can reasonably be suggested
all these come to mind instantly, but obviously matching the applications critical to success, you can,t just select a cam at random without matching it to the application

Oh yeah I completely understand.
Just wondering at this point.
the car will be my 66 Impala (about 4200 lbs)
327/275 HP - 10.5 CR - 1.94 valves
Completely stock Cast iron manifolds all the way.
4 speed Saginaw and a 3.36 rear (I believe although I haven't really checked.)
Id expect you to have no trouble with that first crane cam if you installed it at split overlap in that engine with a manual transmission and that 3.36:1 rear gearing but Id strongly recommend verifying all the valve train clearances, and rocker geometry,and using the crane valve springs set to the correct load and recommended install height, but Id suggest you talk to the crane tech guys

and discuss it before purchasing it, keep in mind if installing it DOT-TO-DOT its 4 degrees advanced, and getting the quench in the .040-.042 range and polishing the combustion chambers to reduce potential hot spots and minor port bowl clean up, to increase air flow sure helps , INSTALLING IT AT SPLIT OVER-LAP WOULD PUT YOUR DYNAMIC COMPRESSION DOWN NEAR 8:1 AND SHOULD WORK WELL WITH PUMP OCTANE FUEL, once youve verified all the valve train clearances
