What are your thoughts, and how much power do you think I'll make. Are there any other mods that I'll need

What are you going to burn for fuel?

Ouch, that's gotta hurt the old pocketbook.

Ever consider E85? Not sure of availability in MO, but I would think it's better than some places.

The high CR is the only concern I would have for a cruiser.

I hadn't even thought about E 85. It's readily availible around here so it might be worth looking into. The track tech is only $5.69 a gallon right now in Holts Summit Mo.
Other than jetting, pump and hoses what else would I need for E 85 and what is the octane rating. Phillips/Conoco rep. said that I should stay above 104 octane with this set up.

Typical for E85 is 105 octane. Interestingly enough, I've never seen an octane sticker on an E85 pump. I can get it for $2.65/gal at the track, $2.75 at a station if I drive a ways, and $3.09 at the closest station to my house. I take 2 5-gal gas cans to the track every time I go.

Pump - depends upon what you've got. If you're running an electric, make sure it's alcohol-compatible and provides a little more capacity than a similar HP gasoline pump.

Hoses - materials are compatible with ethanol these days.

Jetting - Make life easy on yourself and get the Quick Fuel Technologies E85 metering blocks. Follow their jetting recommendations. The PV & idle restrictors are up-sized, and the emulsion bleeds modified to make the carb respond to the fuel properly. You'll convert to 4150 in the process.
