    No, the deal with the flow bench fell thru. Thus will give you an idea how much I opened up the exhaust on the 243's. They're going on a 6.0 with a healthy cam into an ecsb Silverado.

    One day, Ill get a spare set of 862's and take a grinder to them. There is a book about porting and polishing at the local barnes & noble. You think it's worth the $25?

    Is it an Ls based book? Even if its not I'm sure there's something to be learned from it.

    can't remember. My roommate gave me a turbocharging book by motorbooks for my graduation and I found it very informative, so I bought the tuning book and the LSX engine book by them. I'll see if I can find a LSX specific porting book

    There weren't many pics of the intakes, how much would you say you opened the openings?
