lol. Nice someone (you) can see this as being ribbed. We are all doing it in fun.

Are you sure we can’t double dare you to do it ? :wink

What ignition are you running ? If tbolt, which module ?

With boat under load keep advancing timing untill motor suddenly stops. REbuild motor and set the ting 3.5 degrees less than that, your golden.

I am thinking of replacing my carb w/ a Holley efi syst, not much more $ than a carb. If I had an MSD module it would link to the efi and make small adjustment to the timing. I just bought this dist 3 years ago so it;s going back in.

I have enjoyed all the joking around but seriously what would be the best way to set timing after she is all together? 502 .060 over, GM intake 6269318, cam TBD could use some help here, told my builder to call Bob Madara at Marine Kinetics. CMI e top s/s headers, and possibly a Holley efi in a 27 Power Quest Laser

Don’t listen to these guys, there just upset they didn’t think of first.

I thought "Bob Cams" were able to set their own timing!

Holley Sniper EFI with a dual sync to control timing would be the way to go, but you can just get the coil drive and a standard coil. It's somewhere on this page. Holley HP EFI conversion

Dyno...
Or, set timing conservative, make a run. Add 2 more degress, make run. Add 1-2 more degrees, make another run. And so on...

cant go wrong going to the dyno to sort out what a new build wants.

Best advice I can give you and your builder is do not ever call Bob for anything engine related .

Set timing with a timing light.
