I have a 1964 catalina with 67 400 automatic.
My questions are 1: Should i put on a set of long branch manifolds (which i have) or just get some headers (which Indian adventures makes). If i go with some headers how much are long branches worth. Mine have never been put on a car and are powder coated with all the hardware and oil adapter.
Question 2:
I have Flowmasters 3 chambers on and would like a little beefer sound. Should I go with the two chambers or a different brand( my flowmasters sound a little tinny) all together and which do some of you guys run.
thanks for any help
