Thanks M. Here is another pic. from same era, 1966, in Long Island, NY. My car also raced at Bridgehampton. I'd bet it and Thompsons car crossed paths more than a few times.

Note the 1/2" copper oil lines by the battery. The first owner worked at Bast Chevrolet and had great access to parts. This was before it was legal to run the front mount oil cooler. The oil cooler was mounted on the back seat firewall, and the copper lines were run to it. These copper lines were actually the GM freon lines for an A/C optioned corvair. The copper helped to cool the oil also. Everything was fine as long as you had a window open to let cool air inside to the cooler. Sorry for my long and rambling post.

Nice pictures Rick and its an interesting oil cooler. The oil must get hot in the Corvair. In the Yenko Stinger road test in Car and Driver magazine they show a huge oil cooler Yenko mounted on top of the rear fender like on an Indy Car of that era. The story goes that the other drivers protested it because they were affraid it would fall off. In 1967 SCCA wrote a rule to prohibit that oil cooler and Yenko had to change it.

JoeC> That car with the oil cooler mounted on the drivers side rear quarterpanel had #13 on the car. The car was owned and drove by Russ MacGrotty. My car was ordered and delivered new from Russ MacGrotty Chevrolet.

This is the car I have advertised in the for sale section. Now's your chance to own THE "Homoligation" car. This is THE car that made Yenko Stingers legal to race in January 1966.

If we could turn the calendar back to 1965 right now, the crews at Yenkos place were working around the clock to get all of the 100 Yenko Stingers ready for the SCCA man to inspect them. They only took off 1 day, and that was Christmas.

If you close your eyes in a real quiet place right now, you can almost hear the crisp sound of an air-cooled 220hp. Stage III Flat six turning 7200 rpm's. Heehee

Hey Rick how many do you want? Come down to the lot we're having a Christmas special. From what I can see there are about 15 Stingers in this picture with Don showing one to a potential customer. By the way, was the Stage III 220 hp or 210 hp?

JoeC> Thanks for the Great pic.!! I have never looked at that one before.
Stage I is 160 hp.
Stage II is 190 hp.
Stage III is 220 hp.
Stage IV is 240 hp. and too big of bore for D Prod. class.
That info. came from my factory Yenko Stinger Brochure.

Here is some other info. which tells a little different story on stages IV & V.

Happy Holidays to all here. Thanks for a Great site !!

Rick - I have an original data sheet from Yenko dated 1/16/66 that lists the stage I as 160hp, stage II as 175 hp, stage III as 210 hp, stage IV as 185 to 230 hp. and stage V as 250 hp. Did they change the Stinger specs after 1/16/66?

[YenkoYS100]

JoeC> My original brochure is not dated anywhere. I'd guess that it was printed after your spec sheet. Comparing my brochure to my "Yenko Stinger Tech Manual" (dated March 1967), the ratings change once again.
Stages I thru III remain as I posted earlier, in both my brochure and manual.
Stage IV changes. In my brochure it lists a stage IV as 240 hp. and 176 c.i. (illegal for SCCA. 164 c.i. + .040 was legal).
In my tech manual it lists a Stage IV at 230 hp. and goes on to say it's basically a ported and polished Stage III with high CFM carbs. This is the engine that won the DP Nationals in 1966.
The manual lists a Stage V at 250 hp. and says illegal for SCCA because of the larger bore.

Now that we are all confused, I'll quit!! LOL
