Big Block Tunnel Ram 660s Questions
I was talking with yellowrose back then and he told me that with the tunnel ram the most important thing was to make sure that both carbs flow the same at idle. Then whatever the transfer slots were, that’s what they are.
I made one of them tools with the UNI-sync (I think that’s what it’s called) to get the carbs to flow the same at idle. Neat little tool to have handy when working on a tunnel ram. Biggest key is to make sure that one of the carbs throttle links is disconnected at the carb when adjusting.
Bottom line is verify no leaks (air and fuel). Verify timing, and verify carbs are synced. 1000 rpm idle is not a bad thing.
Yeah, I remember when I was setting mine up and was reading all that transfer slot info about .020-.040 exposures. It made mine idle way up there, especially with manifold vacuum on the advance.
