THE KT-BOUNDARY
As some of you know, we teamed up with Drew Pumphrey at D &J Precision Machine to build a Sleeved/Deckplate wet 6.7L longblock for my 2015 Engine build primarily focused on a reliable high HP platform for a hot street truck, with DPC2015 being the event to showcase this build. Drew has invested Hundreds of hours into this build and we are finally ready to dress the engine and put it in action.

D&J Billet Rods, Pressure lubed wrist pin, 1" longer
No Limit Manufacturing cut a billet 187-220 Camshaft
D&J's 7/16 .168 push tubes
D&J CNC ported head that flows right at 300CFM

Damn Lavon :rockwoot:! That sucker is going to chit and get. Now you can really turn up the wick without fear of a splitting headache. Congrats on a killer build.

Looks really good Lavon! Lots of engineering into it. Where did those liners originate? Or are they all custom?
Also, I see you tied the main saddles into the deckplate, how are you addressing cam clearance issues? Do the studs stop short of the crankcase? I think it's amazing how far you have taken this!

Finally a thread for this. I'm sick of Facebook! ha ha

Looks awesome!!!


Is there any worry of the gap between the deck plate and the crank case compressing over time and loosening up the head? What was the goop he put in there? Some sort or epoxy/glue, or was it just a silicone style gasket?

There are studs that tie the deckplate in with the mains top to bottom, but some of those details I'm sure Drew would gladly share with any serious customer.

Sure, I see how it is.... Seriously though, excellent build, excited to see what happens this season.

All the beautiful work and $$$. Bad ass build. Any reason you didn't go with a roller cam? Are they not street able or are there no real gains seen using them? Congrats on this build.
 
We designed and engineered this entire engine for Lavon. We have spent countless hours on it, and have taken all we have learned over they years to try and develop the best thing we can for the High performance street truck. That being said, none of this has been done on a true street truck, we have run deck plate, sleeved engines with coolant in pullers, but the street is a different animal. We are blessed to have a great company like Firepunk to help do the testing, and R&D for a project of this size. When we get all the details worked out, and proven this will be released to the public.
 
Awesome!!! Are you going to step up the compound turbo setup for this DPC reigning champion build as well?

Regardless of who gets in, looks like you're going all out this year to defend the title! That motor looks like it's built to handle big power!!!

We will get it on the dyno and have a few days of swapping turbos from our last year's setup, to s400-s400, and even bigger, the goal is to increase 10-15% HP over last year's 1267.9HP number without sacrificing low rpm response to keep the street driving and towing capabilities to the same standards we had before at a lower power level. The best power curve will determine the final turbo combination.

Fuel setup has 2 Airdog 4Gs feeding 2 Exergy stroker cp3 pumps with Exergy 275% over injectors. This should keep low end fuel quantity reasonable for fuel economy and towing and enough top end fuel delivery to meet our current goals.
