I want to get a set of roller rockers for my street built 351W, but I do not know anything about them. I see you can get a set for about $200 to $400, but I do not know what I am getting for the additional money. Does anybody have some advice as to what to take into account?

Thanks

 

well for street you prolly won't notice a difference imo cause you will prolly be paying for name but i would go with a name brand maybe a tiny bit better quality

 

can u use rollers on a non-roller block? do you need a special cam shaft?

 

if i remember correctly yes and what you are thinking of is a roller lifters with those you need a special camshaft

 

That is my understanding as well. I think you can put roller rockers on any head as long as you use some type of push rod guide. Many stock rockers have rails on the sides of the place where they push on the valve stem. I know some Windsors, like the 221, did not use these rails but rather had slotted holes in the head to keep the rocker arm from slipping off of the valve stem. I learned this the hard way when trying to build a 221. Please do not ask me why I was trying to put a 221 in my Mustang. It was a dark period in my life.
I think they make special roller lifers for non roller cam, but I think they require a special length push rod.

 

call the manufacturer or consult a local engine builder they will tell you everything you need ot know

 

Better off with a beter name. They have reputations to keep. I've always been told that Proform has ok stuff, but don't use their rockers.....

 

I have a set of Crane rollers on my 289 that worked out great.

 

I'm using Comp roller rockers and have had no problems.

 

what HP increase does Crane and Comp Cams claim???

if anything they just look way cooler.....i plan to build a 302 on the side down the road and put it in my car so i wont have to wait around to get my current 302 rebuilt and will prob wanna get some of these......
