454 mag carbed timing??
I have a pair of carbed 454 mags with what looks to be merc thunderbolt distors and MSD marine boxes and Blaster coils..my question is will I still have timing advance modules on the distributors with the MSD boxes and if so what is the procedure for setting the timing? Can timing be locked out with the merc distributors..what is correct timing?? Thanks
