It was the motor Boofhead was going to build for his car, so yes it is pretty special to a few people on the mustang forums.
ShaunP built it for me and did an amazing job.
It's a 347 with scat crank and rods, forged Carillo pistons, Boof's CNC Canfield 195 heads and his custom bullet cam, howards link bar lifters, Vic Jr EFI manifold, crank trigger and a Megasquirt ECU. Zero decked for 10.5:1 compression and ARP studs throughout. Plenty of P2V clearance left if I ever want to up the compression for more power.
