Which Starter?

Having some starting troubles. The engine isnt anything special, 521, 10.5:1, hydraulic roller, .650" lift. The stock starter from 1969 has worked better than the high torque mini starter. I have all 0/1 welding cable for batter cables, all high quality connectors. Wont turn the engine back over if hot. What are you guys using?

Production O.E.M. gear reduction starter from a 90's 460 truck.

Be certain your ignition timing is correct.

Interesting, I tried a used stock starter out of a 95' F250 7.5. and it didnt do any better than the 69' one. I have start retard on and the initial is 10 degrees till it spins 800rpm's. Worth a try to lower it though.

I have seen timing to low cause cranking trouble also. It should start fine in the 10-20 range. You may try to get engine spinning the flip ignition on.

I agree with lance. My 557 wont crank with less than 17. But its 13.25:1 and on methanol. Different animal but still too low is just as bad as too high.
