I run a Comp cams street solid roller in my 10:1 470" low deck. It's 242/248 @.050 with .570/.576 lift. Idles like a kitty at 900 w/12" vacuum and pulls like a freight train up to 6k. Been in my motor for a few years with zero issue. The difference is that he is going with a hydraulic roller. So the reality is that the 0.050" numbers are really not directly comparable, and seat timing will be a lot more on the hydraulic due to the slower ramps. So I think there will be more lump in his idle than yours, but probably okay. It will be a matter of what the OP deems acceptable for idle and low speed characteristics.

I forgot to mention I have power brakes and Edelbrock states: Idle vac. at 1000rpm = 10 As per your recommendations, I must find a milder cam... With 2400 stall and 3.23 gears in a Charger 1967 with power brakes... May be the Comp Cams 23-710 will be a better choice with (.224 / .230 @ .050) (.538 / .534 lift) (110 lobe sep angle).

I don't mean to hijack your post but what valve springs are you planning to use? I got into an involved discussion with a Mopar owner that runs a big roller cam and he claimed even street rollers need a lot of valve spring due to the faster acceleration ramps on the roller cams. He maintained that you'll float the valves out without additional spring pressure.

My stall B&M Holeshot 2400, but 3.23 rear end with 26 inches tires... I have good compression 11.25 I mix 100ll and 94 octane with good results. With 11.25:1 compression you don't want to run too small of a cam or you will have to run 110+ race gas. My old 451 with 11:1 compression ran a 251/251 @ 0.050" solid roller. Vacuum was not great, but worked with my power brakes although adding a vacuum reserve canister is a good idea. I was on the edge with pump gas only (ok on the street at less than full throttle), and normally mixed 1/4 to 1/2 110 race gas with pump gas when I went racing. I also ran a 10", 3200+ stall converter and 3.91:1 gears. What cam are you running now?

Springs I use now are from the Edelbrock Performer Rpm heads 60929
Edelbrock now make Performer Rpm heads 60925 for roller cam...
60929 1.885" = 115 lbs. 1.400" = 280 lbs. 60925 1.885" = 140 lbs. 1.380" = 317 lbs.
I'm planning to use proper springs with roller cam.

You ever give any thought to lowering your compression with a thicker head gasket or something? Seems awfully high given the rest of the combo.
