Anyone used one of these? http://www.performancedieselwarehouse.com/1660205.html

Im wondering what has to be dont to install that on the engine. I.E.- do regular ARP main studs work, how are you supposed to make the spacing up between mains and the girdle?

Swain tech seems to be the place for piston coatings but, has anyone had the chambers of the head ceramic coated?

I was figuring on having the head tops of the pistons ceramic coated. Then have the skirts teflon coated.

Ive seen things on this paint that you apply to the inside of the block that promotes oil return. Not sure if that would be worth it or not.

Also need to know how much to shave my stock pistons to get down to 15.5 CR.

Gapless rings or no? Stockers?

And if anybody has the specs on blue printing one of these and is willing to share them I would really appreciate it.

I think thats all for now.:thankyou2:
 
PDW makes a nice girdle. You have to use some long A1 mains to clear it. Then machine the mains flat and make up some spacers to fill the gap. It needs to be done right. Your rotating assembly is counting on it being right. The spacers have to be set for the correct preload. The same girdle can be had cheaper elsewhere though.
The question is do you need it?

As far as your compression ratio, there is no standard number for machining. There are variables to account for when setting up compression ratio in your specific motor.
 
I was just wanting kida a guidline to go buy on the pistons.

Where do you get that girdle cheaper?

Info on the preload too please.
 
I was told by some big engine builders that coatings are really not needed. That coating the pistons give you mearly extra seconds before distruction. I beleive they may dispurse heat a litle better...but when at the level where you are creating a lot of heat its just not enough.
 
if you want to get the girdle from the source contact kennys pulling parts. great guy and does alot of work for some big names shops.

I would also look for a wider bowl piston. with the stock piston I would shave about .080 and have them coated by swain as well as the main and rod bearings. this will also give you more camshaft options which youll need if you want to run 2.8

I called Kenny's today. $1000 for the girdle kit and $300 to machine everything to fit. The girrdle is 5/8" thick:rockwoot:

He said the main cap spacers should be 0.005-0.008 above the oil pan rail.
 
Checking on another source for the girlde for half price tomorrow.

Still waiting blueprint specs and something on the rings.
