I know I don't need a roller for my application but it's just something I've always wanted to do. Are any oil mod's necessary? I've read Andy's book and can't really get a final opinion on this. So what say you guys? Thanks

For mild street performance and once in a while to the track, IMHO there is a better selection of HR grinds. Cam manufacturers usually assume that anyone who buys a solid rollerr cam is looking for max horsepower. R.

I used the Hughes 5319 lifters, they are only $370/set. The only lifter bore prep was running the Hughes 8319 lifter burnishing ball through the lifter bores. The engine is not as quiet as I thought it would be, but I may be hearing the roller thrust button with the stock timing chain cover? I originally was using 1.7:1 ratio rocker arms, so I used the ISKY 8005A valve springs. The Beehive springs may be better, but are more expensive too. I think if I was going to do this again, I would just use a tight lash solid roller cam with a "street" type lobe profile.

There are also solid rollers that are street friendly and easy on valve springs. I still think it's important to state what your horsepower goals are here. If it were my engine I would go with a solid roller and have the heads ported. You're not going to need a lot of rpm to make power, but it is very difficult to over cam a 440 with standard ports let along a stroker.

A hyd roller is nothing like a solid roller and shouldn't be thought of in the same paragraph. Low RPM street builds a hyd roller may be fine,for a real build go solid flat or solid roller,I even suggest hyd flats over some of the hyd roller stuff. We are talking available MOPAR .904 lifters. Anyone have a low cost spintron I can borrow for a few days?? Last edited by goldmember; 04/05/14 02:56 AM.

If you want a cam to work real good with your combo then I would give Dwayne Porter a call as he is very good. I am very pleased with my solid flat tappet. I drive my car alot and I only adjust the valves once a year and many are not even out. Ron

You have unported Stealth's (budget minded build) and considering a roller cam??? Have you gotten into the details of the cost to run a roller? Certainly mixing it up a bit and doing it your way is cool. Hell, I run manifolds. But if you are wanting the best performance for the $ spent, I would probably CNC the heads, and get a solid FT, FWIW. To your question. If you simply want a roller, it sounds to me like the hyd. roller would be better for you. You'll give up a little power, but it will be easier on parts, and lower maintenance.
