2005 motor, Falicon knife rods, Gen II crank, JE pistons, Web cams, ported, degreed cams, MPC Cam position sensor, Brocks advance pin, Milled head, 2008 throttle bodies, and installed in 2008 frame with 2008 electronics. Great spark but acts like timing is off. Won't start and backfires thru throttle bodies. Any ideas?
