Build for member John S

[Twisted Steel Performance]

Here are a few pics of a build I'm working on for a member here, long block will be assembled this coming week...

Most of these pics are of the heads, CNC ported, big exhaust valves, TSP valve springs, Heat stop in all runners, Heat barrier combustion chambers, 3 angle valve job... Next week I'll install head studs, MLS gaskets, heads, then it won't be too much longer I'll have it on the run stand...

In the background is another build for a boat, it also has the same work done to the block & heads John's does, it will also have the long block assembled next week..

@JohnShead here is your build...

A couple pics of how I install valve seals, I use .530 seals on both and I cut the stock base to fit these more common style seals....

John's block also got a "short Fill", block filler up to the bottom of the w/p holes, cylinders were diamond honed, total seal ring pack, all bearings were ceramic coated, rotating assembly balanced to 1gr front to back spec, pistons were coated on the tops and skirts, modified P400 oil pump, main & rod bearings coated and clearance set @ .002", new Clevite cam bearings also coated. It's going to have HS rockers and custom length pushrods..

Looking great Chris, it's finally coming together. I guess I need to raise the priority level of my transmission rebuild, it's still completely disassembled on a table in my garage, lots of work to do on the truck to get it ready too, my wife is going to love it.

If you have a good rebuilder, take it there.

I'd disconnect the alternator wire check voltage at the alternator

Make sure and protect the end of the wire from arc strikes

Get the paint coming...

Oil system primed, oil passing through all rockers, time to button up...

 

[JohnShead]

Paint is ordered, from the looks of it you'll be ready for it before it gets there.

Are the dimples in the pistons enough to get to 18:1 compression? I thought much more materiel would have needed to be removed??

 

[Twisted Steel Performance]

These are 18.5:1

 

[Twisted Steel Performance]

All painted and ready for the run stand soon, this paint takes a very long time to dry, like 2 weeks, and it won't harden till the motor gets hot... So we wait...

Are the golf ball dimpled piston all that they are cracked up to be?

 

[DieselAmateur]

@Twisted Steel Performance is there an average measurement/ length you're finding in fitting the custom pushrods vs stock? Curious as to how large the difference is. How did you discover that the pushrod length could be increased to begin with?

Who would have thunk decades after the venerable 6.2/6.5 platform was deemed a POS by all that thought they new everything; so many would still be on the road, with more power out of them than prevailing wisdom thought possible.

I'm still loving my 1st one a 98 6.5 that I have owned 2000, my 2nd 98 purchased in 2006 was a running strong Burb when I parked it in 2015 (albeit has some body rot going on after my son had it 4 years in VA where they use road de-ice chems in winter), I just didn't need it as daily driver any more, keeping as a "hangar-queen" for spare parts if ever needed.
