i just got a 6.0l ls1 built and am putting my 6-71 blower on it. the engine when all done will be 800+ hp on pump gas. my biggest problem right now is that i keep getting different information on the MSD 6ls ignition box. i have been told i need to use the 6ls2 box and i cant find one. the engine has a 58 tooth crank sensore gear. this engine is going in my wifes 79 cutlass. i am also having trouble finding headers that will fit in the car.
