How did you end up mounting it?

Right now it's just sitting in there, since I removed the forward console mounting bracket for weight reduction lol. Eventually I plan to put that back in and solid mount the cage to it.

Updates! I found that I was still using the opto-isolator tach input/output circuit with EDIS, as originally suggested by B&G. MSExtra now recommends using the VR circuit, so I swapped to that. I haven't noticed a huge difference, but the placebo effect has me thinking it's running a bit smoother.

 

I'm still having trouble fully eliminating my light ping above 10psi, even with timing pulled back to 15* and running 11.9 afr. I'm worried about EGTs (which I'm not monitoring) if I pull any more timing. I'm starting to wish I'd spent the time on some headwork before reassembling the longblock. Maybe I'll look into installing my methanol kit until I'm ready to take the plunge into E85, but I hate to have to do that temporarily. I just don't know what else I can troubleshoot.

 

I do have a pretty constant miss at idle that I haven't been able to track down, but I can't see how that would have anything to do with my ping.

I haven't done a test run yet, but I'm 99% sure I found the cause of my knock "issue". When I made my custom timing indicator I didn't have a good way to verify TDC, so I just eyeballed it based on the cam marks and never circled back. I bought a proper piston stop, and lo and behold I was set at 11* over-advanced . That'll do it.
