Thumbs up HP, reliability, etc.

I've had TWM injection on my 427 going on 4 years now. Although I wasn't looking for fuel economy, I checked once and found that I get 12-13 mpg and that's with my foot into it most of the time. The computer is under the dash, and I also s-canned the useless Lucas fuse panel for a modern fuse block that's not obtrusive. The engine put out 717 hp @ 6500rpm with 680 ft lbs @ 4600rpm when dynoed while being built by Keith Craft, enough to scare hell out of me and make me vow to sell it, but after 2 weeks I was looking for ways to make more hp. Other than driveability, and performance, (the response is immediate and builds thru the rpm range) the wow factor when the hood is up is amazing! I've driven carbureted cars and they don't seem to pull as hard, that's not saying that there are not some that do! I like it so much that I became a dealer for TWM. It's not cheap, but neither is a Cobra!
