Just got our F1 project truck done and dynoed. We through it on the dyno with 8lb. of boost and we happy to see that it dynoed 703 RWHP. Still having a problem lifting the heads though. Any time we go above 8lb. of boost we have problems lifting the heads. We need to put bigger studs in the heads down the road. The setup includes:
-6.0L block
-Custom Diamond Pistons
-Lunati Rods
-Stock Crank
-LQ9 Heads with bigger valves
-AZ Longtubes
-Blower cam
-& we keyed the crankshaft
