700hp Butler engine will run easily on 92 octane. It isnt a cruiser engine it is nasty, but they can make a 500-600hp engine with plenty of grunt on the bottom for street driving. Usually for less than $7k you can get a very reliable and powerful engine from them.
Here it is running doing a half throttle burnout. Its more than enough power for ya, I am sure.
Also if you have E85 available in your area you can crank up the compression and make lots of power, your engine will last longer, idle better and have more mid range and bottom end power. I have two 455s running on ethanol right now, they are monsters. This one will go on it as soon as I get the 1050 Holley converted.
KRE, Kens Speed and Machine, Paul Spotts, and a bunch of others can make silly power too, but Butlers are plain awesome. They have great customer service and will talk with you as long as needed to figure out what you need to get what you want. Jim and David are good people, Jim and I talked for a couple hours at the shop one afternoon. Stand up guy for certain.
