Beta Hunter's Engine pack 2.5

Added an LS to the bluebuck, currently the 4.8 and 5.3
Should note the stock hood is the only hood that works without any inploding, this is becuase of the node placement in the engine that I have to fix, but other than that it works really well with a stock hood

Added the more LS engines to the barstow, 5.7 (chevy 350 basically), 6.0, 6.2 and chevy's 6.6!, currently the ecu's for the barstow are bugged on the vortecs and that is somthing ill have to fix

Also added a I6 diesel sound to the LM2 duramax, turns out the beamng devs had one in the game files and that was neat

Up next is probably an engine model for the chevy 2.7L and a few fixes and the rest of the vortec engines imported to the barstow, may even do the duramax engines if I feel fancy, for blue buck too and the van
