In the process of rebuilding my 5.0 HO, I am reusing the production heads (E7TE)and would like roller rocker arms, pedistal mount type. I'm looking at Ford performance or Crane. Can anyone offer advice that have used either one.
Use the Ford/Crane Cobra bolt down Rockers , cheap tested tough by Ford and me. I've got about 60k on a set with a stage 1 TFS cam in my 351 Lightning. The shims are a bit of a pain but follow the directions. If the engine has never been apart they should go on with no shims . If you have to go more than .045 on the shims I get different pushrods. My never been apart engine took 0 shims . My 351 took .015 but thats got milled heads (.015) etc . Good luck Bob
related question here, I bought the crane ones and have not installed them yet. Are these going to need guides? I thought I could call Crane but the answer here might help others. Thanks in advance....Steven
wasn't sure because in the description under self aligning it says......... no. But I like you thought only stud mounted ones needed them. the self aligning no in the description has thrown me off..............Steven
Many thanks to all for the info, I ordered the Crane rockers yesterday, the kit includes shims. I guess I'll need to check valve to piston clearance during assembly. With an "E" cam and 1.7 ratio rocker I figured a lift at the valve of about .528 in. instead of the stock .498 in. Using stock 5.0 ford pistons with valve relief cut in the tops.
