WOW, I did not catch that note. I thought that he had 24 degrees of initial timing at 500rpm idle in D.



Correct. I read 24 initial and that huge RPM drop indicates there is something going crazy. A huge vacuum leak, etc. It should idle easily like the car in that video, 16 initial/34 total all in at 2500. 24 is a lot with that set up.

A stock converter works fine with an xe268H, no need for a stall converter with that camshaft.

I think there may be an assembly issue. This has been an ongoing series of threads on another board. I doubt the camshaft was degreed so there is no idea where it's installed. If assembled correctly, cylinder pressure should be in the 160+ range is my guess. Hopefully it's something easy hooked to the exterior of the engine.
