Cooler intake manifold

I used to run my alloy-headed 367 DD usually from May long weekend to September long weekend; sometimes from Easter, occasionally to as late as October 10. It ran a Hughes 223/230/110 cam, and a 750DP; no choke, no concessions ... other than the Jacob's dash-mounted, dial-back, timing module. Sure I had to babysit her for a minute or maybe two on cold mornings.
Have you put a scanner on your EFI car to see what the factory does with the cold timing? Think high 30s to mid 40s at idle, increasing with rpm, until you give her more throttle. Check also the step count on your AIS motor; which may not be that far open..... Most of us, with non-stock engined carburated cars, already have a working Idle-Air Bypass system, in the form of, holes drilled thru the primaries........ so then, all a high-compression engine needs is a bit of extra advance, during the warm-up.
Chokes are for people who want to go back inside and drink coffee, and maybe their behinds get offended by cold seats. I don't drink coffee/ car has cloth seats.
In winter, same car, ran a lo-compression 318; with a Thermoquad, and yes a choke. But usually with a 904 and a 2800stall. And yes, with block-heaters too, and studded snow-tires. What a hoot that car was.
I still don't drink coffee.
Three things I can guarantee you;
1) I will never smoke cigarettes, and
2) I will never drink coffee, and
3) I will never be willingly jabbed.
4) there are more but ...
