Roller rockers on bb

[Mr. Belve]

Best roller rockers for a bb. Opinions on hp gains.

Buy the Crane Roller Rockers they are the same as Mopar Performance except you are not paying for the Mopar name I have them on my 495 Indy head motor had the same ones on my 440 cast iron head motor never had any problem with them

I have the Indy SR's on my 440. Don't think there is alot of hp gained into going with them over a set of reg adjustable rockers. I like the Indy pieces because of the spacers that come in the kit. They have a solid spacer to seperate the rockers instead of springs. It was real easy to make the rockers align up in the center of the valve stem. Alot of people are using the Cranes with good results also.

Is it worth the money for the hp? I'm not gonna spend it unless it's worth it.

Most of the lower end rockers only have a roller tip, not the full roller fulcrum (sp) on the shaft. The roller tip reduces the friction on the valve tip for some HP advantage, and less valve guide wear. Some of the other advantages besides being adjustable, are less weight (more RPM before valve float), and a more accurate rocker ratio (the stock rockers varied alot, and had lower than 1.5:1 ratio.)
