GM Aluminum Block Small Block Chevy Casting 0 359198

[STEFS]

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.

Thank you guys. I believe this is the same engine as the one being discussed above:

Cant remember.

I bought that engine (those photos were taken in my family room) from Al Maynard (Mecum auction at Indy, 2015 maybe?) and sold it to a collector in California (I think his name was Len) and he sold it to Jim at Heartbeat City. Some really cool history with that engine, it was built by Keith Black Racing Engines and awarded to a lucky winner at Good Guys (?, not sure of the show) in Columbus, OH, by Car Craft Magazine. Another one I shoulda kept. I just picked up some more neat experimental stuff.

So......................................... has anyone determined WHAT GM made these blocks for? Trans AM maybe? Expiring minds would like to know.

Rex, they were probably for Grand Sport Corvette, Chaparral, or simply for development/experimentation. I guess Indy is another possibility since Smokey did try a "stock block" Chevy there.

When I saw this engine it was in the car and it looked drivable at the time. Just speculating on this... I'm thinking it was a "one off". It seems to be the ONLY one in existence, so if GM was going use them for Trans Am etc would you think they would have made more?
We would have seen more of them too... Smokey had lots of pull, could he have got Winters to make just one?
