Short block 68086564AB orRL086564AB Crankshaft 5038339A The 6.4 crankshaft is forged, correct? Does anybody know if the 6.4 crank has the same oiling issues as a 5.7 crank does? Wondering if it is a good alternative to aftermarket forged crank for a stroker 5.7 motor.

Stanton Racing (drag pak builder) told me the drag pak cars need 11.5 quarts between the pan and accusump. And there are at least a half dozen guys running stock 6.1 cranks shifting at 8200-8600 rpm and all have been fine for 2+ years. Also- for those planning builds- the VVT motor cranks require machining if you want to run them in a non-VVT motor. -'02 Dodge Viper Ex-World Challenge racecar -'73 Duster, 6.1 based 392 hilborn hemi, tko600, full floater rear 9", Hellwig custom bars, viper brakes, built for road course

I agree 100% with you Stef as the Molnar stuff is only like $100 more...But you never know when you might catch a good deal on a 6.4 crank, and I just thought I would ask since I was unsure if the oiling issues was restricted to 5.7s only, or also 6.1's and 6.4's also.

The VVT crank needs the snout where the crank timing gear rest against to be machined so the gear sits in the same factory location on an NON VVT block. Simple process. The cam in a VVT block is longer. Steff posted some pics when he built his 6.4. Matt

Stock 6.1 cranks generally go for about $150, are forged and can easily handle most power needs. Buy a set of good rods, pistons and studs and you will have a stout combo. On the flip side the price for aftermarket rotating assemblies is very affordable. OST Dyno - Home of the worlds Quickest and Fastest Supercharged Hellcat!

And there are at least a half dozen guys running stock 6.1 cranks shifting at 8200-8600 rpm and all have been fine for 2+ years. Stanton mass produced the Drag Pak engines.For whatever reason he ground down the 6.1 rod journals to except Chevy SB rods. Whomever he chose to grind the crankshafts down must have been "someone" with little or no knowledge how to properly grind a crankshaft. After disassembling the Stanton fresh built 5.7 the first red flag rose when I noticed was that some of the supposedly zero deck pistons where either sticking out of the hole or in the hole which tells me that "someone" didn't know how to index a crankshaft properly. And the worse cluster mess up was that one piston was .006" above deck on the pin side and .005" in the hole on the other side??? .011" difference from pin to pin on a 3.917 bore. How hard on the rod bearings would that much deflection on the rod journal cause? I brought this up to Stanton himself but I'm not inclined to tell you what his suggestions were cause he'd probably plead the 5th so I made the decision to scrap the crank and grind a new one that I had on hand. So that brings up the question as to how many Drag Pak owners used their Stanton built motors as is and blame oiling issues as the reason they windowed a block? Anyways, just to be safe a Molnar crankshaft was purchased to replace the OEM 6.1. Jerry Williams.

No. The only ones affected were the 6.4 and the 5.7 eagle head motors. 09 and up for the 5.7. I think the 6.4 came out in 2011.
