Virg, I had the same problem. trie everything, new starters,new battery, new ign.switch.new cables. till some one here at the bolt put me on to a heavy duty starter. Mine said he was for a 1975 chev G 30 van v8/350 Bought it at murrays for $52. returned the old one that I bought from them for 36. their bosch # 25374. murray # 1047204 It spins it so fast I am astounded. Trust me this is the answer.
