Is this started yet, or still in the design phase. Is it going to be turbo? Tube chassis? Sounds like a cool build, let us see some pictures.

Still collecting parts.

Non-turbo high-compression pump gas engine. Considering a custom solid roller from comp cams with RT280/NC284 (int/exh) lobes and a 112 deg lobe separation angle. It will lift about .666" at the intake valve with a 1.6 rocker. DesktopDyno estimates BMEP's of 218 at 5500 rpm which should yield over 470 horsepower at 7500 rpm. The wide separation angle should yield good low rpm torque with DesktopDyno estimating almost 300 lb-ft at 2500 rpm (stall speed.)

Planning a tube chassis with a-arm front suspension and a triangulated 4 link rear.

Will post pics of the parts as I get them cleaned up and prolly do a build thread on Pirate 4x4.

Re: syty powertrain love

I think it's easier to simply swap the t-case. Why do you need all these parts w/o turbo and stuff...

Re: syty powertrain love

Are you planning on using your jeep off roading? A high reving 4.3 build is probably not your best engine choice. You can do a 350 for a lot less than a Bowtie 4.3 build and have better low end torque.

Yah.

Tough audience here...

I guess the thread title should be 'inspired by' syty powertrain love.

Anyone know where I can get a syty 27 spline transfer case input shaft?

From anyone who has gone 4l80E. Via changing the input shaft. There was a group purchase a little while ago where at least 20 of the 32 spline shafts were made. Put up a WTB post in that section, I am sure there is someone here willing to offload the old shaft. I would if I had changed mine out.

I have a 27 spline shaft sitting in a oily rag in the shop. Make a offer. I don't need it.
