So slowly starting to get some things accomplished and slowy parts are coming in. Already posted pics of the rods but will post again and keep this thread as my update thread. Got my block back from one of my machine shops, added 14mm main studs (extra long) and went through the girdle plate and had them make hardened spacers between it and the caps. I have a ton of other stuff I am waiting on hat should come together in the next couple weeks and will update as I get them...

How about compression ratio....going to lower a bit? The rods might appreciate it.....good deal with the girdle!
 
Pistons are going to be custom turned Mahle's. Taking 24v pistons that have a lower ring landing and solid top (no cooling passages) and turning those on a lathe to hve600 series bowls to fit my 05 nozzle pattern. This will drop cr some but no positive how much.There has also been head work done to lower cr that I did a long time ago.

head is gettin full port polish, intake is gone and getting custom tubular intake done up. Adding w/a ic after my spearco a/a cooler. getting tubular exhaust manifold. John is doing me up a couple Stage 3 pumps. Also one otherthing up my sleeve I hope to have before TS but I doubt it happens.
 
Hey thats a good idea with the pistons. Re-shaping the bowls will lower compression somewhat and you should be able to keep the quench area tight. I'd be great see some photos when you get them!

Bean...This wouldn't have anything to do with what John and others are working on.:evil Seams like your building her for some rpm.
 
what happened to the old engine? or are you just doing a "start from scratch" upgraded engine to replace the one thats in the truck?
 
Bent the rods on the old one so starting fresh.
 
Can you please tell me how much material is left in the plate on each side of the holes you drilled for the stud to pass through?

If you have good enough eyes you can see it looks like just over a nuts width, so maybe like 3/8"?? My eyes aren't calibrated! Just spend the money like we talked!
 
On the front and the back of the plate the nut and washer hangs over just a hair, all of the center ones there is plenty.
 
I called them and the cost was actually about 600 more than we thought!!!!!

Couple more things have shown up.

Here are the piston I have been working on. Bowl is about 13cc larger then the 600series piston. We took a 24v vp piston and tuned it to get it as close to a 600 series as possible, reasons for this are the 24v piston has no cooling pasages for more strength, ring land is further down the piston and over bore 600 series pistons were almost impossible to find.

Stock 600 series for comparison.

Also this thing showed up....

That works out to about 14:1 compresion .045MLS gasket or 13.5 on a .060 oring? I sure like the looks of that, bigger bowl, (tight quench) and the lower ring land, IMO that 600 piston is a dud......
