Run a Hydraulic roller grind, but use solid roller lifters.

My cam is about as big as Isky generally uses in a daily driver situation and has served me well for over five years. After my 9-sec pass, I decided to change out the springs and the old ones were somewhere around 220-230 on the seat and 480 open and I drive it a lot and had several passes at that time. I swapped to a stouter spring and it`s still goin strong w/240-250 seat and 540+ open. I`m not the consertavite type and am of the "bigger is better" theory and so far have proven it can work well.

Ron,
Ive talked to Dwayne at length about this on a couple occasions.
He says the -5 Comp lobes are very very reliable in a real street driven application.

And Dwayne is right.
I got my -5 grind from PRH and it has been very good.
The first design street rollers are nice grinds too, though, and worth checking out if a guy wants to buy a shelf grind.
I was going to go with the older 308 street roller until Dwayne picked out a -5 for me instead. At the time our feeling was the -5 would pick up some power without hurting reliability/longevity enough to notice.

No she is in Pa.my dad`s family are car guys but ford`s and chevy`s. my dad owned a few mopars but never long. I wanted to be different and took alot of ribbing for running a mopar. i have thought about a roller cam for a street strip car small block. i thought that unless you get solid body lifters you had to bush lifter bores.

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
