Got the frame and cage pretty well done for the race truck, now im geting around to the engine. I've built plenty of performance engines, but nothing to this caliber. I'm aiming for 675-700 hp, from a small block. Gotta keep it light. Gonna use a virgin 400 block with Milodon splayed main caps, Eagle 4340 4.00" crank, Eagle 6.0" H- Beam rods, and a set of JE forged pistons. It will be balanced (obviously) Does this sound like it should stand up to you? If your interested, the top end will be a Brodix 18* Al head kit with a single plane and an 850 Demon. Cam is yet to be decided other than its gonna be a hydraulic roller with an AFR rev kit and shaft mounted roller rockers.
