Stripped out lower waterpump bolt that goes into engine's front cover 350
Got this '71 350 Rocket and when I was putting a new waterpump on it one of the lower bolts that goes into the front cover on the engine, not into the block itself, stripped the threads in the hole I think. I was wratcheting it on and when it got to where it almost seemed like it should be getting tight it started spinning freely.
So I think it's a 1/4" bolt with a 20 thread pitch. The holes in the front cover don't have much meat around them but I'm wondering if anybody else has done this and knows if I could get away with upping the size up to I think 9/16"? I don't know much about tapping a hole either, do I just drill into it with a 9/16" drill and tap it with a 9/16" tap? Or is there a better solution? Maybe this bolt could be left off being that it's just 1 of many and isn't going into the block anyhow?

I don't think you want to be drilling into the cover since that would send metal shavings into your oil pan. I think the best solution is to get a different cover or weld a nut onto the back of your cover.
