Thanks for all the input, the OP really appreciates it!! Really just wanted to show that more expensive is not always better & aluminum is not always the way to go. Brian at IMM produces a great product with his EQ heads and I wish I had just left well enough alone. I have a 3.91 gear & 3500 stall dynamic converter. So I guess my next option to see if I can get some Bang for my buck is a bigger custom cam & a larger single plane intake. Hey at the very least I saved 100lbs in weight...lol
