Noisy Starter
Does anyone have a great method of starter installation to minimize starter noise? My '72 350 starter is an OE starter and has the rear support. The starter was stupid noisy so I loosened the rear support and the two large bolts. I then held the starter in place by hand while I tightened the two large bolts then tightened the rear support. Much better but still too noisy.

Re: Noisy Starter
Usually too much clearance between gear and flexplate, but some times not enough. Use a screwdriver to push the bendix out of the starter and engage the flexplate. A standard paper lip should fit in between the valley of the flexplate and the bendix gear high point. If more or less space, the starter needs to be adjusted. If too close, full length shims the that run under both bolts will move it away. If too close, you can shim the starter just on the outside bolt and that rotates the gear closer to the flexplate.
Sometimes due to age or tolerance stacking a particular starter just won't work on a particular engine/flexplate/flywheel combo. My '69 short step and its 307 are like that. I have shimmed the outer bolt as much as I can and it's still noisy. At some point I replace the starter but am planning on doing that with a motor swap as well.

Re: Noisy Starter
I take the starter out & run a big coarse flat file over the surface on the starter that goes up against the engine. This gets the irregularities out of the mounting surface & brings the starter gear closer to the flexplate gear.

Re: Noisy Starter
Like Mike C said you may have to shim it, most auto parts stores sell the shims and spacer tool, the tool is nothing more than a piece of 1/8" round rod.not a paperclip,that is too thin....comes with instructions also, but just go between the high point of the starter gear to a valley on the flywheel,like stated above

Re: Noisy Starter
I found this on youtube when I put my mini starter in. It is for a MSD starter but the theories are the same. I added both shims to mine to get it aligned right.
