Crane Hydraulic Rollers

Re: Ford 2.3 Rebuild, Boat

Well I mocked it up and without any milling I am at an honest 9.0:1. Chambers are ~ 68.4cc, deck height -.025 and piston reliefs are -3cc. I understand the lowering of the CH to compensate for an overbore and not blowing the compression up. I will use a .041 HG and leave everything else alone, settl...

Re: Was this cylinder scoring caused by previous builder not using torque plate?

You are in the fine blades of grass there with the plates. First the guy needs to know how to size properly and develop a proper crosshatch. Plates, surface finish, crosshatch angle, sizing all important. Plates more important on some engines.

LS 7deg Locks

Looking to use PAC R655 steel retainers with a 5/16 valve that has standard square groove. Pac lists the retainer as being compatible with LS 7 deg locks. Will this work?

Re: Valve Springs?

Have a look at COMP 7245. At 1.9" installed height it would be right there. It is a conical dual with 600# rate, up to .835 lift or .735 at 1.9 installed height.

Re: Blasting media to restore as cast finish to alloy?

Once sand blasted die cast aluminum is changed, will never be the same. Sand castings can be brought back. I did this comercially in the 90s and still do some today. It takes acid, electricity, and different dry medias. At home sand castings can be restored with a fine glass bead finish then brass b...

Re: Another lifter question

The difference is Harleys have cylinder growth (and shrink cold). A SBC not, so they are usually set on the top side of the .200 plunger travel. depends on the lifter.
