Honestly I have not had many issues with MSD, but not opposed to trying new. One nice things is summit stocks msd and they are local to me.

Must have been like glass last night! Smooth camera action @ 5800 RPM. Glad you got it fixed now. I'll be up in a few hours, I'll give you a call and we can go grab lunch somewhere, Westbay for ribs???

Tim have you thought about DUI distributors and what to other people think about them?

Yes the bay was flat, with smaller props I saw 70.5 in humid flat water..going to put my labbed 25's back on today, bring them back to 5500..

Yes we will hook up I'm sure, scott was talking PIB maybe hmmm

What ones?

Not nearly as good as a GM HEI.

That was short lived put 25's back on and dropped 200 WOT On port... I give up, these props were even in Zachs boat... Also high 10's to low 11's air fuel at WOT. Lighter load with 23's must have been the fix not the coil. I give up its slow....

Or... I have 3 sets of props with a crap left, but 2 are mint props labbed.. I think next is to swap drives and see if it follows.

So next question... if the problem goes away with a lighter load (though still a decent load) Is the load with 23's greater or lesser than the load the dyno put on the motor?

Is the reluctor clean? Maybe swap out the magnetic trigger? I'd swap all ignition stuff between the motors before I swapped drives.

As mentioned above about the DUI heir ignitions. . . Pretty simple system. I've been looking hard at switching over all my MSD stuff to DUI or something else in an HEI.

Ok after pulling my hair out thinking again, I called Mild Thunder Joe... We decided it's most likely the extra load on bigger props, making the one emgine go rich and lug, took out 3 jet sizes in secondaries and see 11.6-11.9:1 and both engines 5400 equal, so guess I just needed even less jetting then before the small props allowed the engines to run easier...

I can't say how great of idea it is to have full time widebands to check this stuff! I think we got this now!
