My suggestion would be a 2006 or newer Vortec 4200 (295hp), custom flywheel, Vortec 3500 5-speed, and have Westers Garage re-program the ECM. then you have 5 wires to hook up. Battery, Ignition, crank, fuelpump.
Then again if you are going to build the 215, there are easy ways with a crank change from a 340 to get 300 cubes out of this little engine.

Scott: Are you sure you can run a Vortec 4200 inline six without all the wiring harness and sensors stuff? I hads not seen ANY articles or ads in any of the research I have done that says someone supports this. Does it retain the EFI, but eliminate the closed loop operation (since no sensors to provide the reedback data)?
IF so, that could indeed be a dynamite package.
What about size? How does it compare in length and height to the Stovebolt sixes?
I'm really afraid of that Buick route. I spoke with a guy who apaprently knows a l;ot about them and builds them, and got scared off by both the costs of proeprly building one and the peak power available. He would not guarantee even 275 hp, despite the displacement increase.
The 4200 could be magical if someone offers a simple, non-harnessed and sensored version. I don't want anything to do with those wiring harnesses and sensors. Had enough of that!
