I have sprayed around the carb area with starting fluid without result. throttle shafts are nice in the bores. not loose. I have been up and down with the timing both with the vacuum connected and blocked to know that I'm not going to solve the problem with timing. At this point I am thinking I...

I have had it connected as well, makes no difference.

I have played around with the timing, mostly with the vacuum advance disconnected. No help. I think right now the timing is at about 0 degrees with vacuum disconnected.

I could be wrong, but the "nailhead parts interchange" shows the interchange between the 364 and the 401-425, not necessarily between the 401 and 425, right?

I will plan on using the stock gaskets. Thank you kindly for your input.

rebuilding with stock cam, .030 over.

I'm rebuilding a 401 from a 66 wildcat. Basically a stock build. I want to run it on pump gas, which around here tops out at 91 octane. Should I be looking for some thick head gaskets to reduce the compression?

I just purchased a 1938 Buick special and will look forward to reading posts about it.
