You want the 410/420 HP from your 355 CID small-block that the Edelbrock "Performer" rpm "Power Package" provides, but you want to use a hydraulic roller cam, what do you do? Use the Edelbrock Performer rpm hydraulic roller cam, that's what. There are two versions of this cam, one for non-roller cam blocks and one for OEM roller cam blocks. Designed to work from 1500-6500 rpm, these cams will make superior power, while reducing friction for even more performance. Cam specs are as follows: Degrees duration @ 0.050" valve lift - 234° intake and 238° exhaust; lift at the valve - 0.539" intake and 0.548" exhaust; lobe separation - 112°; intake centerline - 107°. These cams are intended for use with either OEM or aftermarket hydraulic roller lifters.
