I've built 2 of the 59L relieved blocks, both were new never used blocks. I assume they were military surplus as we had 2 large airbases near here. I found both blocks in old machine shops. I did one with Offy heads and a Roadrunner blower and one with 2 94's and Offy heads. I used 4 inch Merc cranks and bored them to 3 5/16 and did all the other usual stuff. Both ran good and with Walker Z line radiators and 16 inch electric fans ran reasonably cool.
