Hi guys. I have a stock 235 in my 59 apache with 4 on the floor and 3.38 rear. I have been looking at Clifford Performance Header/intake/Weber kit as they claim more power and better mpg with this set up. Anyone here have it on there bolt? At over $1200.00 for the kit I would just like to hear any pros or cons before I put down that kind of money. If you have used them or know any info either way on this setup please speak up. Here is the link for the one I'm talking about. http://www.cliffordperformance.net/...roduct_Code=C-235&Category_Code=C235
