i have an aftermarket cam made by cranecams if you want to buy it, ill have to find out what its worth. i think its a .420 .420 lift cam but i dont remember.
but the cam opens and closes the valves. so thats prob why its not running.
the timeing does have alot todo with it running also.
the cam i have has to be used with a carb 2.3 i think.
