Some cars are just cold natured, and it is hard to know why sometimes. My Son Don is running pretty much the same setup in his 23 that I am in my 27 (sbf, 2 x 4 Edelbrock 600's) and yet his is a little slower to warm up and take gas than mine. I think he even has his choke wired in and mine are both wired wide open. Very confusing.
