    My 70 Z28 4-spd has the 168 tooth with the 621 bell. The starter is a 680.

    There are differences to be considered. BUT, in your specific case, ONLY a starter with a STAGGERED BOLT PATTERN AND A CAST IRON NOSE will work!! That is, in regards to a stock type starter, NOT an aftermarket mini starter.
    Any starter with a straight bolt pattern will work with a 153 tooth auto or manual flywheel.

    A starter with a CAST IRON nose and staggered bolt pattern will work with either an auto or manual 168 tooth flywheel. BUT, a starter with a staggered bolt pattern and an ALUM nose will ONLY work with an auto tranny flywheel (flex plate). The reason is because the starter bulge on a bell housing for the big flywheel is too small for the alum starter nose. Thus, only the cast iron starter nose will fit into a big bell housing. For the smaller, 153 tooth flywheel or flexplate, it's not an issue.

    So, you need a staggered bolt pattern starter with a cast iron nose which is what came on all BB/4sp cars and SB cars with the 168 tooth manual flywheel.

    Up until 1962, the ONLY size flywheel was the 168 tooth version. Then, in 1963, the smaller 153 tooth flywheel was introduced.

    Another topic, starter bolts:
    Starter bolts are a SPECIAL shouldered bolt! DO NOT use a regular bolt, buy them from a GM parts dept. There are 3 lengths: short, medium and long. The cast iron starter nose requires two MEDIUM bolts, part number 3733289. The medium bolts are ONLY used with the cast iron nose.

    The alum nose with the staggered bolt pattern uses 2 long bolts, and the alum nose with the straight across bolt pattern uses one short and one long bolt. It is imperative that starters be correctly aligned, so that the starter teeth and the flywheel teeth mesh properly and don't chew each other up. That's the reason for the special shouldered bolts.

    I had the same problem for my 168 tooth BBC 4 speed. 1998 Tahoe 454 mini starter saved my problem. Same as original starter only smaller.

    Starter is a 6449 lester # it will fit SB and BB , they weigh 10 lbs and work fantastic . You will need the bots for proper installation . Try and buy a GM starter instead of the cheap knock off auto parts and ebay stuff.

    I am running a 90s vortec v8, muncie, with 168 tooth flywheel and 11 inch clutch and I used the Remy p/n 96206. Works great. Hope this helps.
