OK I want to put a full 2.5in exhaust, an intake manifold set and 3.55 gears, I have CAI + 70mm TB already. If I go with Thumper's E7 head set with a B cam and the timing chain set for $895.00. use stock rockers, pushrods and so on can I expect to see some substancial gains? Would like to see 270 to 300 @ wheels to give those pesky LT+S1's a good run (in the quarter not top end) and even hold with an 05 mustang. Am I shooting too high, also want to keep some mileage I drive a lot on the highway.
