Before making such a purchase find the rpm range you use your engine at and then look at the curve of the new engine and compare it to the curve of a stock engine. You MAY find the stock engine has more or the same power in YOUR range! MAny guys hop-up their pickups around here only to find that it ran better before spending the money!!!
If you are NOT going to use 6,000 rpm then do NOT build for it.
