Great to hear, I just finished my 305 and have somethings left from my rebuild.
Machined crank and set of .020/.020 main and rod bearings. Found out my engine was a 1974 305 and took a different main bearing (bigger), so the main bearings are for 60-73 motors.

Good luck with the rebuild. Dont forget to replace the oil pump, I found out there are two different ones too based on the size of the oil mounting bolt. They are NOT interchangeable.

Thanks tbucket! I will PM you about your left overs . I am going to pass it on to my brother so he can tell me what exactly we are going to need first but I'll hit you up.

I definitely have the oil pump on my list since that was the one thing I was worried about before. Thanks for the heads up, I will get the specs off the original to verify.
