Just buy a ferrari 458 motor and drop it in. You will have your v8, 9,000 RPM revving, one of highest hp/liter motors right there.

Not sure either of those would be any cheaper Building the F22x2 might actually be! $20,000 for a replacement E/90 Bimmer motor I know. God knows how much for the Ferrari!

I'm trying to get in touch with Synergy Power to see what all they had to do to put two I4's together for their V8.

Endyn is actually doing this but using K series heads. They developed a reverse K series head. They have pictures on their facebook page.

$20k is probably cheaper than a getting a custom block and crank made

You could always look for the engine out of a current Ford Gt350. Flat plane hi revving V8. Even though swapping that into the S would be a pretty big undertaking I would think it is probably easier.

"The hand-assembled 5.2L Ti-VCT V8 with a Flat-Plane Crank (FPC) found on the 2017 Ford Shelby GT350® is the most powerful naturally aspirated road-going engine in Ford history. With a redline of 8,250 rpm, it's also Ford's highest- revving production V8 yet."

Here is a V4 Harley from back in '08




Saw the V4 Harley at the '08 toy run(over 3500 bikes) mine is out there somewhere.

Here is a video of it running

I wish I had the video of him taking off for the toy run, one little twist of the throttle and smoke was coming off the rear tire.

I just looked that up, that's freaking sick. I'm just glad to know it's all possible! I just need to get into the engineering to figure it out. D:
