My 307 leaks like a seive... I'm upgrading to a '67 327 within the next few months. Dollar for dollar, it'll actually be cheaper, I'm buying a nearly complete 327 with all machining done, just the heads are left to rework. I was actually going to go to a stovebolt (my favorite) but I had to do the math and go with the one least likely to force me to sleep on the couch
