Damn...Motor Just Blew! Need Advice!

[sixtyfour]

On my way to work this morning a rod let go and motor started knocking. Was able to limp it home and here I sit waiting on a ride. The motor that's in it was either a 305" or a 350", I never took the time to figure it out. I want to go back in with a mild 350" and I need to do it as soon a possible. If I do have a 305" now, all the accessories, exhaust, and clutch/pressure plate will bolt right up...right? Anything I should look out for? Also, any suggestions on where to get a new motor? JEGS, Summit, etc...? I'd love to go back with a stroked 383" but I need to be realistic since this is my daily driver.

thanks
