pretty awesome looking engine set up. i like the fact its built on a gm LS platform, which means rebuilding the engine would be easy/inexpensive , and making even more power with them will no problem. the LS is a super stout alum small block... the camaro ZL 1 makes 650 hp, and there is a LOT more in there

The more props in the water the more slip 7 to 14% x 2 or 3 or 4 so with 4 that's 28 to 56 % slip and the 557 still has all the gear change of a bravo.
Sorry just not a big clamp on fan for 80 grand I'm sure I can make more hp then that and beat the piss out of it every day 2c
