    I have a clearance issue on my alternator, unable to decrease belt tension and that ends up is with full tension almost maxed out, alternator hits the oil filter, not sure if it’s because I have a bigger oil filter? Even if I put a smaller capacity filter it still doesn’t look like it would be enough clearance!

    Is that on a 304? On my 232 and 258 the alternator and oil filter are on opposite sides of the engine.

    Have you tried a shorter belt?

    Yes, 304
    Shorter belt means moving alternator in, it hits the oil pump, and the belt that I have barely sets tension, won’t last as belt stretches and you have to adjust, it’s already maxed out

    I ran into this same issue as I upgraded to a larger alternator on my 304. You can either grind the case of the alternator a bit for clearance, or get a slightly longer belt and install a adjustment rod like I did. The benefit to this is that you get to use a wrench for getting the belt nice and tight. This is the adjustment rod I used: https://www.summitracing.com/parts/SUM-420302

    I relocated the oil filter using bulltear parts helps with driveline clearance too
