Just curious if any of the people who run rollers in street cars use the street roller cams that use less spring pressure then race rollers ?? Thinking about using a roller in my next eng for my 63 but I do drive it alot on the street. Ron



FWIW I had Lunati do a street roller grind for me for a Hemi. It's a very mild 242@50, .590 lift with 110 lobe sepearation. The trick is to have gentler ramps on the lobes. I ran comp rollers and Isky gold tool room springs that have 190 on the seat and 450 open.

We ran it on the dyno up to 6500rpm with no float issues. It was still making power at 6500 (we just chickened out)

One of the better decisions I've made. You can barely hear the valve train and it idles smooth at 950rpm. And you don't need any lotions and potions for the cam, no break in.......
