New to the board--rockers???
 

I've read long enough. Time to join this great site. I'm still in the learning stage. I bought this 86 gt with a late model cobra 5 liter, stock heads--gt40s with factory 1.7 rockers, e303 cam (so say the one responsible), carb, msd, and headers. Valve springs may be heavy enough, checking this monday.

Question: rockers were machined at the roller's tip to avoid rubbing the valve spring retainer. (the ears--not the roller). The roller strikes the valve dead center. I just can't believe I have that much lift. This was a home grown job by someone. Should I go with 1.6 rockers and if so what springs are needed using that e303 cam.

Thanks and open for advice.

Senior citizens love their rockers--mine are made by Crane!

i have the e303 cam in my car and it only has 498 lift, so i dont know why that person machined the rockers, i cant help you on what springs to use(i have the ones that come on edelbrock assembled heads) hopefully someone can help you with the lift info.

Thanks sn95gt19 for replying. Nobody else has heard of this either. Crane and Ford say this combo is a normal bolt-in. Maybe the cam is of a larger lift then e303. The idle to me sounds more radical then the e series cam.

Still open for info while I continue the tear down.
