318/XE262/#302 heads and what stall converter/rear end

35 total timing?

If so DO NOT do it that way... Total timing method is a ROTTEN way to time a street car.

Put a timing light on it at idle and see what you have. If it's not on the range I mentioned, set it there and reset the carb. Get a vacuum gauge to set the carb, highest vacuum, leanest point on mix screws.

You may have to bust into the distributor to hit your total number.
