doing some mods to my 598.
I bought the Holley smart coils and was thinking on going with a crank trigger and cam sensor instead of the dual sync distributor.
Are these the right parts
MSD cam sync and oil pump drive P# 85141
will this work with a tall deck?
Holley crank trigger wheel 36-1 tooth P# 556-113
or should I run the 60-2 wheel

Great
What about the wheel?

I run the 60-2 it supposedly gives slightly better idle with more precise crank position. Some drag race guys have had issues at high rpm with it though, my setup has been rock solid to 6400 rpms.

Either wheel will work fine at marine BBC engine speeds.

ATI makes some built in trigger wheels..
ATI - Crank Trigger Shells

Would this be a better option so pulleys belts and such don`t have to realigned due to the extra wheel?

MSD / Holley has them as well.

The higher the X the better the resolution. for a jist

I always liked to keep it simple, dual sync worked fine for me.

I don`t really want to move and realign all my accessories to fit a flying magnet in there
Figured this would be a nice option?

Alex Haxby pointed out he likes to use a dual sync with a billet cap, no need for a seperate crank sensor.. seems like another option.
