Just wondering about your solid roller lifters. Have you talked to anyone about how long they will live? I've got them also but I will have to rebuild them "often". I have to run them because of the RPM my motor turns but I didn't think any of the big motors would run anything but hydraulic rollers.

I'm not a Ford guy but if I were you I'd do some checking around as you don't want to have a failure. I'm planning on buying another set of Isky's (their the best for my engine but may not be for Ford's) and change them out every other season and send them back to Isky for a rebuild. That costs about 11 dollars per.

Everyone I've talked to about this has told me to be careful as the damage is done most by LOW SPEED driving and especially idleing although any valve float will fail them faster also. A rev limiter is a good idea.

4Aces you probably have hydraulic rollers right? If not read the above. Also it goes by spring pressure over the nose of the cam. Mine is around 620lbs not counting the "rev kit" springs over the push rods.

Hope this helps,
