I had worked at Hank the Crank in ca and we did build Flat cranks for guys like Ryan Faulkner race engines and Traco and Chaparral. The crank u have looks like a billet to me with center counter weights. If to check on the front counter weight it will tell u the stroke and both rod and main sizes if it’s a HTC crank. Also looks like a Avaid oil pan Weaver Dry sump and Norris stainless steel rockers and maybe BBC push rods. All the people I mentioned were in the Los Angeles area. As far as “0” dash # goes the parts that I have from Jenkins had the part in there box an the new GM # after the 0

Thanks Stefs,

That is some great info. I have already stashed the engine back in its spot. I will check the front throw for stampings next time I’m near it. I looked it over pretty closely earlier but could have missed something. I’ll have to tear it down at some point anyway. I’m torn about what to do with it. It is a cool piece as it is but could also be great with a larger bore and stroke.

Thanks,

Jason

Thanks for that Joe... I knew Yunick built a 200"ish" CUI indy engine. You saved me the trouble of trying to find the specific info.
