sm block Camaro header question...

depends on how much collector you have. slip fit connectors work very well when used with a band style clamp and are almost as easy to remove when needed. youll need at least 4-5 inches of collector to slip a pipe onto and seal properly when clamped. almost all modern muscle uses slip fit exhuast these days and it works well. do your collectors line up with the cross member exhaust humps?

my Hookers end before the crossmember on my 69 Z/28. most flanged headers end about 6-8" before the trans mount. Don't think I have seen any headers with welded flanges end after the cross member. would be real tough to install. usually long/short collectors are used to establish a torque range for the motor I believe.
