To upgrade intake manifold on not?

RPM. The AG-RPM will have cold weather issues. It the regular RPM since it has a heat cross over. Your gains will be mild.
Have you run one?
Because I have. I’ve got over 25k miles of year round daily driving in my Duster, and like I said when I start my commute in the winter it’s not uncommon for it to be in the 30’s. Occasionally colder than that too. I haven’t had any more “cold weather issues” with the Duster and it’s 340 and air gap than I did with my Challenger and it’s mild 318 with an edelbrock streetmaster, which has a crossover and wasn’t nearly as high strung as the 340 is. And by that I mean nothing beyond the typical old car with a carburetor that needs 5 minutes to warm up kind of thing. If there’s a difference it’s minor, and nothing that can’t be dealt with.
An AFB & a RPM-AG?
Ahhhhhhhhhhh, yea, I have. That’s why I said what I said. I’m not talking out of my *** here. Why would you think (via your questioning) that I would be doing so.
Though I really see the need to proof read what I write. LMAO!
Allow me to Clarify something(s).
A bit of a more detailed response as well.
I suggest the regular RPM for the heat crossover.
I don’t suggest the regular RPM-AG during the winter.
You will
Most likely if not certainly (geographical location dependent) almost definitely, 100% have cold weather issues. Why?
The most common set up’s are a basic carb & 1/8 - 1/16 thick gasket on top of intake with an open air cleaner. There is no heat in the intake or carb. It is possible to have icing issues as well. (again geographical location can have an impact on this.)
There are ways to help avoid the incoming freezing cold air from closing the choke even if the engine temp gauge says your warmed up.
A closed air cleaner like a factory unit.
Adding a heat stove off of the manifold or header.
While heat is a power looser, it does help drivability in the cold winter days.
@72bluNblu - While I live on Long Island, about as far south in New York as you can be, the winters can fluctuate in severity. On the low end, winter days can be in the teens with overnights well below zero. Other times it can be mild in the low 40’s. The mild temps do not apply here.
Also....
@Wvbuzzmaster Did not say much in order of how he is running his set up which leaves me to fall back on the worst thing, assumption, an error on the cautious side that someone will always find room to comment on how there stuff runs great and mine doesn’t with a side poke of I must have ether no idea what I’m doing or I have never done that.
At what exact temperature the problems started at, I do not remember. But I do know West Virginia can get pretty freakin cold! (Been there done that.)
This has been my experience with the RPM-AG intake and AFB carbs with an open air cleaner up top during the winter.
At what outside temp your running your car at with whatever set up you have, IDK. From where I stand, it sounds like you have magic air for your car.:poke:
How is your set up done?
OH! 25K yearly?
NICE! Very nice.
