KULTULZ Sorry about not replying sooner. It seems this NEW POSTS feature doesn'twork correctly.

The shafts, spacers and springs are still available from vendors such as PERFECT CIRCLE I believe.

paulo Thanks K.I just got hold of a good book by Steve Christ.They mention this misalignment and the cure. By the way,don't you have a set of rocker shafts with spacers and springs? We need to buy them.Our 390 is missing some bits.

You need to enlargen the upper shell holes to match the galley feeds. The shell finish needs to be radiused and smooth.

The lower shells can be used, but like Bob mentioned, allow less bearing area.

...until some ford guy answers but,, was there some deal with certain FE engines where you needed to 360 deg mains to feed the rods because of the location of the oil hole?????

I really do not know why i am thinking that but it just popped into my head... Like i said don't get freaked out because i could, and probably am totally wrong. I might be getting it confused with another engine family...

If that is a none issue i would use the bearings that only had the top groove... 360 degree mains are not needed IMO...

The 427MR used grooved mains as it had a cross-drilled crank. High speed operation only. No great benefit for the street.

BOBCRMAN@aol.com The solid bottom gives you MUCH more bearing load surface. If your oil system is done correctly there is no need for the 360 groove.
