Welcome to CHR:

Ouch!! 16:1 can not be domesticated. Finding fuel will be close to impossible and expensive. I've built a few 500HP 383's and they're very unruly on the street and do not behave well under 2,500 RPM.

I think you'll find it less expensive (as mentioned by Charlie) to replace than to tame this beast.

Good Luck,
Glenn
