i have a stock crank here. i think im gonna take it to the machine
shop and get the rod journals turned down so it will fit my rods (grp alum.)
and stick it in there then i will know for sure.
just a reminder i have two other motors here that run fine on this ignition.
both have stock cranks.
i should have it back together by the end of next week.
and i will keep you posted. thanks again , matt
I would be willing to bet that the waveform generated by the callies reluctor wheel is probably not exactly what the MSD is expecting to see. It would probably run ok with a stock computer, not that it matters in your particular instance, and while I wouldn't go as far as calling another company's product "junk" to a customer, but MSD isn't known for their reliability or quality either. Pretty much anyone who has owned a 6A for any real length of time can attest to this. I have been witness to quite a few of them going toes up over the years.

well i got the stock crank back from the shop yesturday. put it back together last night, and installed it to day. and............ it started right up and ran fine
NOW WHAT SHOULD I DOgonna call callies in the morning and have anthor talk with brooke.
so callies tried to pass the buck along to MSD when it was the crank the whole time. idk how to handle that one. i've never had any luck disputing with a speed shop/motorsport parts maker.

spoke with callies on monday and told them it ran with the new carnk.
they had allready sent mine back out to me and said theres nothing wrong with it.he called me back on wensday and said he needed my crank back again.
they think they have found the problem.
the counter weight next to the reluctor on a 4'' crank is really close to the edge of the wheel, and it causes interferece with the msd signal(apparantly only msd) and on a stock crank ,the counter weight is further back from the edge. now there gonna turn down the counter weight and rebalance it .
should have it back in a couple weeks. i will know more then.sure hope this fixes it.

i guess the next step for me is going to be a
front mount distributor. kinda sucks because thats one of the reasons
i got away from sbc in the first place

Does the engine not run with that Callies crank? Is it shutting off? I had problems five years ago with a stroker, and it was the crankshaft. The voltage with LSx setups is very forgiving. My reluctor was freewheeling and so it would throw off the pcm.

Revive old thread? IDK if it's ok to try and revive an old thread, but, my two different 6010 boxes will work on one motor but not the other. The one the doesn't fire will fire if the spark plugs are removed, but not when there is compression. I have tried changing sensors, wiring harness, plugs, boxes, starters, coil packs, ... Even pulled the crank to check the reluctor. Both motors have a scat 4.125" crank. Both have run. Oddly, the one that runs now had this same problem 3 yr ago. The other one, which won't run now, was fine, with either box. I never figured it out back then but after taking that boat apart and storing the parts, I reused the parts on another boat this year and they were fine.
