If you can't tune a carb or don't want to monkey with it, then vac secondary it will just kick in when the engine demands it (and self adjust if you have too much carb...i.e. open enough to use the secondaries if it can).

Mech carb you will be doing a lot of test runs to get it weighted and timed right if mechanical.

I run a quick fuel 650 DP, and a small 3300 converter.
It hits pretty hard!

I run a 650DP on my 272ci with a stick, but I'm WIDE OPEN from start to finish (launch 7000, shift 7000, go threw 7300)...
