Never ran one before but never built an engine with this much power, was wandering what you guys thought. Engine is going to be shifted at 7200 rpm, about 575 horsepower. Thanks

I didnt set mine up with any preload, I didnt have a mill around to make the caps even, pluss I didnt like the fact of putting a stress riser on the caps. So I think its a good deal, and glad we have hughes engines, and Mancinni out there who specialize in our mopars. Kasey

I've never run one... with my stock block and a 3.79 crank I was running 8200 rpm and the mains and rod bearings looked great every time I opened it

Went with billet mains instead. Exactly...if you cannot locate the CAPS themselves, then it's of no benefiet. That's why the jap engines have the main caps cast together with the girdle all in one...that's the best way IMO. Brian Brian Hafliger

Already no space for a stud under there The caps are milled flat on top, and spot milled on the rear cap so that everything is at the same elevation. No spacers in the equation to make it more effective. It is a band aid solution for using the stock block and caps, but sometimes a race block just isn't in the cards. I have had the engine a part after seeing a fair bit of RPM and everything checks out nicely, so it seems to be doing something to help. As for clearance under the oil pump, it is tight! We use an Allen head grade 8 bolt counter sunk 1/4" and the clearance the pump housing, and shave a bit off the top of the bolt head. -Kenny

sshemi top fuel S Joined: Aug 2004 Posts: 2,128 sweden	my 416 stroker doing about 650 hp had a girdle and everytime i took it apart it had cap walk signs. Come on who thinks a piece of 1/4" (or whatever it was) of sheetmetal would do any good? If i would put it in a wice i think i could have bent it with my bare hands. aldough it makes a nice windage tray.

Good luck bending 1/2" by hand. We also had it on an "R&D" project with some Honda journal rods that didn't quite make the grade. number one rod came apart and smacked the girdle hard. Didn't bend the girdle at all. -Kenny
