Default Rocker Arm Help Needed
I just finished my LE2 Head and cam swap and two hundred miles later one of my pro form 1.6 rockers broke for no reason. I have been gentle with the car and did not have it to tight or loose. It clicked a few times and broke out at the bottom. I have heard good and a lot of bad about pro form. I went with them because it was what Lloyd Elliott sugested. My question is what do you think is the best rocker arms for my setup. I have LE2 heads and 226/232 578/.574 110 LSA cam, trickflow chrome molly push rods, comp cam studs and 15 pro form 1.6 roller rockers left. I appreciate any and all help and sugestions. Thanks

Aluminum is lighter but much weaker than steel as far as metallurgy goes.

So, it would be a really bad idea to say, use something like the Crane Gold Racing aluminum rockers on say, spring pressures that saw up to 470lbs on an engine that revved over 7000rpm?

For the money the comp cams gold are nice. There are several other mfg that make a quality product that will do what you need.
