He can build whatever he wants. It's his money. But after spending some time underneath the car, and thinking...just isn't worth the effort to me. Too many obsticles. Not a lot of room as it is down the tunnel. Rear end needs a lot of cutting and beefing up. You have to steal a car in order to justify all the trashing you have to do to get to where you need to be. I have found some pretty good buys on track car lately, without the motors and trans. Sometimes I think, buy an old '65 vette track car, and add my own goodies and go play again, and sell the XF's... But there is just something about the XF's that are different. Not ready to give up yet. Good luck kid, build away, just post photos or it didn't happen.
