the only problem is it has been sitting since 1996 and suffered from a front end collision and the valve cover is bent, the runner is dented and the pullys are bent also. can i just get stock runners and still run a mild cam in it or will i need upgraded parts and i also want to run a underdrive pully system on a DD is this a good choice? Also it didnt come with a harness or ecu, is there a decent priced stand alone system because i want to put it in a s10
