I wish I could do more for you and Annie, it's just awesome that this car is in your hands and not another huge collection.
And thanks for the thread, learned a bunch, and thanks for sharing. Mike |

Rick; Sorry for the delayed response. The engine is .030" over--strangely enough, when we checked the bores on initial examination, they were actually pretty straight--but they were just over .002" oversize, which would've left .0075"+ piston to wall clearance with the original pistons. That would've rattled like hell when it was cold which obviously wouldn't do, so we had to go .030" with new pistons to get the wall clearance where we wanted it. The heads are bone stock with 2.19/1.72 valves and a 3 angle valve job, that's it. The cam is pretty close to the factory 143, but with a little less duration and a touch more lift (I never divulge exact cam specs, that's up to Rick if he wants to reveal them). The LSA is fairly close to stock, and it idles much as the 143 cam would. Since this is a 4 speed car with a 4.10 gear, Rick & I initially discussed spicing things up just a little, but since this car will never be pounded on and hero dyno #'s weren't part of the plan, I decided to try to pick up as much low end and mid-range torque as I could w/o sacrificing anything up top. I'm pretty happy with the results, esp. considering it surpassed my goals (460 lb.ft, 475 HP) on the very first pull. FWIW, coolant temp was 180° and total timing was 36°. I wasn't able to test with the headers I wanted to use which I know for 100% fact cost at least 20+ lb.ft <4000 rpm. The plenum divider was left intact as well, which left another ~20 HP upstairs on the table, but I didn't want to sacrifice the low end torque to get it. We also could've cooled the engine down to ~130° and found another ~15 HP, but again, hero #'s weren't the objective and I wasn't going to go pounding on the #'s matching engine to a $200K+ car just for bragging rights. I want to thank Rick again for the opportunity to play such a large part in this build. I'm honored, and I'm grateful. |

Another oddball. Our 69 had what appears to be a 68 Malibu dash plaque on it and can be seen in the original photos. The photo is what I took off a 69 parts car (upper) and what was on the Yenko (lower) which I believe to be a 68. Ours is a March 69 car so not early by any stretch. Has anyone ever seen this in their COPO as well? This car what totally unmolested as far as interior and chassis goes so in no way do I think someone changed it out in the first year of its life.

There is a white 69 Yenko Chevelle I’ve seen that also has the 68 Malibu dash emblem. Definitely were a few 69’s they came this way for whatever reason.

If i had to choose based on appearance and correctness a 69 malibu dash plate would be the way to go. Who knows how a 68 plate wound up in there but i wouldnt put it back unless there are other documented 69 yenkos confirmed being delivered this way

Jim S's 69 Forest Green Yenko had no 427 emblems anywhere, no hood stripes and the stripes did not say Yenko SC on the body stripes. I wanted to restore the car that way but he won out. Again, changing history is not my intent so regardless if this is not the correct plaque, that is what came on the car and what will be going back on. I have heard from a couple people already that state they have seen 69's with this plaque.
