Re: L72 block
321 casting used June 67 thru mid jan 68 Earliest ive seen is F77[June 7 1967] and the latest ive seen is A188. Jan 18 1968. It is used on any 427 vehicle low or high horsepower,not just corvette. I dont think its feasable to have a 942 block in a 68 427 car,in fact its very unlikely as the 351 run lasted almost a year before the 321[latest date known is around June 66 on the 942. Its probably pushing[although possible] it to think a 351 block was in a 68 yenko too.

Re: L72 block
So, it sounds like it is likely that a 321 block would be correct for a 68 Yenko Camaro?? What other block castings would be poosible for 68?
Were Aluminum heads ever used on any Yenko 427 engines that were sold to the public? Thanks again.
