I know you said not a KA

But honestly, it's a great motor with boltons...

If you want to have fun, drop a built KA24E in that bad boy and carb it...raise the redline to like 8.5 or 9. I've never really heard of anyone wanting to do something so outlandish, especially with the cheap cost of rebuilding a KADE with forged internals and big injectors and spraying the piss out of it.
