I recently picked up a 90 GT, and when I bought it, it sounded great, ran good and I thought everything was fine. Since I bought it, I barely have driven it because of all of the snow we've been getting, but now it is making a knocking sound. Any idea what this could be?

sounds like a broken push tube or loose rocker arm. possible adjuster nut came off top of rocker etc. Pull valve cover and take a look.

I'll have to do that. I'm waiting on the TFS top end kit to arrive to throw in and I freaked because I thought it was a bearing.

Loose flywheel bolts are also something to check for.
