1968 Yenko Questions - Page 3

My understanding is that when the cars were converted at Yenko the 396 was pulled out and the shortblock was swapped with the crate 427 L72. Everything including topend that could be used from the 396 was put back on the 427. This saved money for the dealer and the parts worked. The MV suffix on the 396 was probably an emissions issue. I think there have been several threads outlining both of these issues here before. There are more knowledgable people here than me that can help with the suffix question. We are talking 1968 here only not the factory copo's of 69. Good question.

I agree, all the top end parts would have been saved. The must be some original cars out there to verify which parts are original. I heard the 851 intake was used on the 68 COPO but have never had it verified.

Just an interested bystander here but I always understood the MV suffix was specified to include a larger carb as it was destined for L72 conversion although not all MV suffix cars got one?.
Searching online results in threads noting #3925519 carb specified for the 9737 option instead of the production #3959164 DZ carburetor?.

I heard the same thing. In my research everyone told me that they couldn't verify the larger carb being used on a car, so I should go with the crowd and not cause questions. I went with the DZ. It seems that if cost was an issue to the dealer, and it usually is, they would just reuse the carb from the L78. Also I think just the 9561 copo was available in 68 the 9737 was with a factory installed 427?? What do I know, I was 8 at the time.

Dana, has the resto been completed on your car? Any current pics? I remember reading the post of when it was found out in the desert... curious to see how it's progressing!

Thanks for asking. I have collected just about all of the parts I could find. I am doing another car now and then it is next. I can't wait to see it on the road. I will post pics and update here.
