choosing a cam
Hey guys im new to this forum but not to the FE! Im in the process of putting in a new cam and want a little input from some whose been there done that. What im looking at is the lunati voodoo and the comp cam xe256h. Its a daily driver, performer intake, holley 600, headers, pertronix ignition, 3.50 gearing with a 3 on the tree. Lunati has a 207 and 213 duration at 050. 112 lsa, with 512 and 524 lift respectively.comp has 212 and 219 at 050., 110 lsa, with 486 and 498 lift. What do you guys think? Ive heard these comps can be a little hard on the valve train.Would like to get some feedback asap. Thanks.

new cam bearing can certainly be put in but not likely with the engine still in the vehicle

Same cam problem here
Two weeks ago I pulled my cam from my 390 FE and with mine the same cam bearing is damaged.... I allready orderd a Crower Baja beast cam (16915) and some other stuff to rebuild the 390. I hope the block issen't damaged from the worn bearing....

your block should be fine , the bearing itself has a softer inner metal that can wear over time. Ive learned that most cases the bearings are fine as is, unless your rebuilding the motor then change them while its out.
Thank you Roger. .
