I am looking at a 268 degree cam (description below) for my DD the 91 Jetta GL with a basic 8V RV engine. Would it be worth the trouble to put in? I do have the lousy exhaust. John It came out of an 8V GTI, I used it for about 5,000 mls, and then purchased a 276 degree. The brand is Techtonics, Its a great cam. Good for head work and a tuned exuast. Sorry about the mix-up VW Sport Camshaft For 8V Golf, Jetta, GTI
