High compression all motor build. What makes it serious is the money I would be putting into it and to get a car like that on the dyno and have it blow up would probably cause me to jump off a tall bridge/building. Even just rebuilding the motor, i.e. piston rings, bearings, retiming the motor, is shit I would want to do several times over with someone who knows how to do it.
edit: no, Lance and I have done a cam swap before, wasn’t too bad but I could not have done it alone.
