Roller Rockers
Hey guys another ? for ya. I'm thinking i'm just gonna go buy some roller rockers. So steel or aluminum, i know they are great for reducing friction and less weight = higher acceleration so what you boys reccomend for this? My truck aint no racer but i'd like to put on new heads prolly later (aluminum) and it's gonna just be my normal driver/street buster. Thanks fer the help.
Also 1.7 ratio is stock, should i bump it up to 1.8? Lemme know

You will probably need taller valve covers.
I heard from rep. people, aluminum ones, won't last on street long. So when I did my camaro motor I got the comp cam stainless rockers. VERY NICE. Been 100% happy with them.

Ihave used Erson and Harland Sharp roller rockers. Hven't had a problem yet. I run a small block and I did have to use taller valve covers.

I use the roller tip comp cams steel rockers on my sportsman 2 heads. Probably doesnt help a damned bit but they were free from a relative who's project was cut free due to an unforeseen childbirth type incident . I have read that aluminum rockers last 30,000 or so on the street which is a pretty long time if you think of it especially on a special purpose vehicle that isnt daily driven. Ive used them a lot in the past and never had problems but then again I've never racked up that kind of mileage on a set. I really doubt some of the manufacturers claims of 30 or so HP by adding a set. They never do put up a side by side comparison as proof and I am dubious of unsubstantiated horsepower claims. The best ones seem to be the comp cams stainless rollerized fulcrum . You dont get the metal fatigue of aluminum and they are rebuildable. stamped streel rockers will be the longest lasting given adequate oil supply though.
