What is everyone running for ignition? I'm building 2 502s, 9:1 prob 741 cams, will run n/a for now and put b&m 250s on in a couple years.
I have one 7al2 and a pro billet distributor. Anyone have reliabilty issues with these? I've used them for years but never in a marine application.

Here is a link to the company that make the old Crane boxes....

Why not good old GM HEI?

going to put blowers on next year, and want/need rev limiters

Thunderbolt ignition on twin 502 na, stock 415hp, but should be good to 600hp. Go with a merc product.......pretty sure my thunderbolt ignition is over 15 years old.

what do you do with the rev limiters all the thunderbolts have rev limiters built into the modules not questioning just curious have a similar motor setup and was thinking about switching to those cams but wondering what i had to do to get around the rev limiters in the tb5
