CRANKSHAFT(S)
Why so many crankshafts? I'm taking these crankshafts to a well known local shop who will add material to the shaft for increasing the stroke (more then the 3.895 existing).
CAMSHAFT
I'm going with a custom grind camshaft from Mike Jones @ Jones Cams in Denver, NC 28037 (704)489-2449 . Mike's a great guy to work with and attentive and maintains contact with his customers regarding there project and detail oriented. (Thank you SilverXJ/Chris)
Off topic but in reference to my old next door neighbor:

Dave McCain & his partner Ed Houtz
Rods, Pistons, and other goodies…?
Rod length: 6.125 stock 4.0L size
Piston: probably .020"-.030" over and looking to do JE asymmetrical but they don't have the Jeep 4.0L forge size yet. (still a somewhat new product line still expanding offerings)
compression goal 7.5:1
meth/water injection (most likely)
T3/T4 tubro (still going through the learning curve here along with the rest of the build)
Pics of the engine(s) to follow.
- If someone needs rods (5.875") the older style cylinder heads or intake manifold even the carb let me know. We can work something out to get them to you. I am using the cranks strictly from the blocks acquired for the project.
