Any luck finding that sonic map sheet Mike??. I am also curious about the spacing between the bores, what size drill bit fits?. Thanks for your time...John

Last time I was at the shop I had to take off in a hurry. I did intend on looking at that block but had to run. I may be there sunday to look.

SOHC Bob had one and together we studied it carefully, but never mapped it (obviously was not worth it)
The cylinder walls were massive thick. like 3/8- 7/16 thick, but they still had a large opening between them, maybe a 1/4" drill bit! It would have been a push to make it to a 390...
