bang for the buck

[V.waffe 3]

What about a aluminum type 1 cased motor versus the type 4. I heard that the major down fall of the type 1 is the magnesium case. I do not know if this is true or not, but I have also heard that the reason the type 4 is longer lived is that it has an aluminum case. I was also wondering what you guys think of a Chevrolet Corvair motor? Some guy who works at the VW shop I bought my car from is big into the Corvair. He was telling me that I should swap out the 1600 for the Chevy. I have seenthis done in some VW books, but always felt that it was kind of redneck, I guess. In the Midwest everyone puts 350s in everything so I felt that it was something along those lines. Though I have heard that the Corvair motor is supposedly rated at 140hp. I would love to hear what you guys think. Oh, before I forget is the 2.0 a true Porsche engine while the 1.8 and down are VW. I have heard this and was just curious.
