Starting Troubles - Help Please

Having some starting troubles on my 68 SBC - 327
I have had starter problems for past 2 years... After the car warmed up, I got the dreaded "click" sound...(car has headers).. so I installed a brand new mini starter a few months back in hopes of solving the problem. With the new starter I also installed a heat shield.. I also cleaned up connections to starter, The car has a brand new battery and new wires to battery...

The car often, particularly when warm, starts strangely... Super Slow, stalling cranks, sometimes, just clicks... but after a few tries it cranks over perfectly... i captured a minor example on video.. in the video, the first start is "weird" then it cranks right over.. any advice would be helpful.. Thanks

Re: Starting Troubles - Help Please

Have you tried replacing the ground cable from the battery to the engine?

Re: Starting Troubles - Help Please

Is your timing set correctly? If it's too far advanced, it will sound like a bad starter.

69 SS, 350/300 h.p., M-20, 12 bolt, matching numbers.

Re: Starting Troubles - Help Please

The timing is advanced a bit.. i believe 8 degrees... timing will be adjusted tomorrow.. If it is the timing, would the starter problems be intermittent and only happen when cars hot?

The ground on the battery is new..

Thanks for the input

Timing problem would be more pronounced when the engine is hot. 8 degrees of initial timing is not alot though. But give it a try, nothing to lose.

Min cable size should be 1 AWG and ground tied to the block.
Battery may also be too small and not be able to generate enough current during the start action. A battery reading across posts during start/cranking of 9.5 volts will be a good indication.
Could also be not enough charging voltage to replenish battery, especially true if mechanical regulator is still installed.

Re: Starting Troubles - Help Please

When the motor warms up the resistance increases in the starting circuit and a poor ground becomes an intermittent ground.

1. Replace ground cable from battery to motor.
2. If missing, replace ground straps from motor to chassis.
3. If anal like me, install additional ground large ground cable from chassis to motor.

Also very similar is if you do a lot of short trips as I do...most are less than 2 miles, and cold starts...once a month I put the car on the battery charger

And do any of the cables or connections get hot?

I would start there. If you have small cables they need to be upgraded anyway. I made my own from 1 AWG bulk cable from NAPA. Autozone has Duralast Gold in larger sizes that are pre-made.
Steps' question above is a good one - if the cables get hot they are either too small or there is a bad connection.
