<<I'm willing to be crucified if needed, but I'm fairly positive that the only VW sourced engines ever to show up in a Porsche product were the 914 and 912E (same flat four T4 engine) and the early version of the Porsche 924, with that oldball amalgam of the Audi 100LS block and weird overhead cam head w/Vega-style adjustable lifter cups. I'm also fairly positive, in fact quite sure that all the 356 engine variants were of Porsche design and construction, though were somewhat similar to VW T1 engine designs.>>
You are correct. My previous arguments referred to the vertical fan fours which do resemble VWs externally. BTW, which American car used the Audi/924 block? 924 owners are still trying to live that down. RLE
