    Just converted my K5 to manual with a sm465. I had a th350. My question is, is the starter going to work for the manual setup I now have?

    Thanks

    I have always wondered the same thing too.

    I have put on 5 new starters on my 85 K30 in the past 5 years and everytime I went to get a new one, the parts man ask me if it was an automatic or standard. So, I guess they are different, but dont know how.

    Word of advice: Get a lifetime warranty starter. Those rebuilt ones suck and dont last. I replaced it the fifth time with a lifetime starter and never had problems again.

    I always thought they were the same until my friends went out on his '68 camaro (auto.). I had one off of my Elco (4sp)that I wasnt using so I said he could use it. He put it on and it kinda grinded. He went to get a new one and the guy said it didnt work cause it was for a manual. I dont know how either, as long as both starters are for the same amount of teeth on the flywheel it should work, right? Hmmmmmm.......

    I just swaped a motor and cab off of a Automatic on to a frame with a manual in it. We ust the starter off a 2wd turbo 350 and put it on the motor bolted up to a sm465. Works Great. Just like normal.

    As long as your flywheel and flexplate have the same number of teeth it should work fine.

    GM has only used 2 different setups on all small-blocks, big-blocks and 90 degree V6 engines. Either 14" diameter, 168-tooth flywheel or 12-3/4", 153-tooth flywheel.

    The large diameter flywheel uses a starter with 2 offset (diagonal) mounting bolt holes. The small diameter wheel uses a starter with 2 mounting holes that are parallel to the back of the block.

    Most engine blocks are drilled for either pattern, so only difference is the flywheel diameter. Many aftermarket performance starters have dual pattern mounting holes that can be used with either starter.

    If you are using a stock replacement or remanufactured starter, just make sure that you have the proper one for your flywheel or flexplate, based on diameter and number of teeth.

    Other than that, the only other issues are clearance for headers, if you have them, and making sure that you properly shim the starter for the correct engagement. Otherwise, you can chew-up the teeth on your flywheel/flexplate, which is a real pain to replace.

    So, in your particular situation, you will only have to change starters if your new flywheel is a different diameter than your old flexplate.

    One of the "original" differences were that the std. starter had a steel nosecone to make it stronger. In the early days of High compression, A std trans could "kick back" when started. So GM used steel nose cones because the aluminum ones would break off and leave the starter hangin by the wires. with the lower compression engines of today, this is less likely to happen.

    your right. I don't understand the jeep thing!

    Ok got the new motor started today and the starter worked fine. It grinded a lot at first, then I shimmed it and the grind went away. Works like a charm now. Thanks guys
