This one wouldn't be too street friendly as shown here, but it could be "dumbed down" a little bit for street use.

This one was for a bracket race customer of mine in Wichita. Needs 112 octane as it's 13.5:1 compression, but at 777 hp @ 7000 rpm with 630 lb-ft of torque, it could afford to lose a few ponies to a lower compression ratio. Every once in awhile I get a guy wanting to put something like this in a Cobra, so I thought I would throw it up here.
This engine as it sits would set you back around $25k.
