single plane in cold weather

anyone on here running a single plane manifold in the winter time? im building a new engine for my 1989 K2500 and am planning on running a weiand team-g intake. on other forums i have read about ways to cure lack of manifold heat. suggestions so far are epoxying coils of copper line under the manifold and running hot water through them.

other thought i had was to build a heated TBI to 4BBL adapter, or run both.

are there any other suggestions on how to heat this thing?

What's wrong with letting it idle for a few minutes before driving off?

I've got a single plane on one of my Camaros. It's not easy to move when it's cold, but it can be done. Usually involve lots of clutch slippage.

If you have the choke set up properly you shouldn't have very many problems. I wouldn't run hot water through a heater plate under the carb. Sort of defeats the purpose of the air gap. Having a hot air riser into the air cleaner will help too.
 
if the choke is working correctly,it should allow the truck to warm up correctly by richening the mix.as long as you let it run a few minutes before taking off,you should be fine.i run a spacer on my truck which basically makes it a single plane since the gap is opened inbetween the carb and intake.just have to pump it a few times before turning over and never had a problem gettin it running.
 
well i am planning on letting it warm up anyways, as i do now, but my concerns were that even after warm, the manifold airgap would cause icing problems. if i were to install a heater, i would disconnect it in the wintertime.

also its gonna be on a TBI engine, so choke should take care of itself with a decent tune. i will have problems tuning out the AE from what i have heard, but thats another thread within itself.
 
are you worried about fuel icing,it shouldnt.even in extreme weather in alaska gasoline shouldnt get like diesel does and gel.as far as ice on maniford,when its warm it will evaporate.doesnt take long since heat rises from the block.either way i wouldnt worry about it.tbi should take care of itself if its tuned correct as you stated already.

from what i have heard, fuel will ice up on the throttle blades and cause them to stick, and others with the same manifold have reported no problem. just wanna take any precaution. when its in the teens below zero where i live, just wanna be safe not sorry.

you can always add a can of "heat" additive to the tank when it gets below zero.eliminates the water that could be trapped in the fuel.ive never had it happen,but stranger things have happened.i would think the engine heat would be enough to keep the upper end of the manifold free from ice.the block is 200 degrees and heat rises and keeps it warm under the hood.maybe someone else has had the freezing throttle blades thing happen.sorry i havent given you the answer you wanted.but ive never seen this.ill have to do some research.
 
That weiland team g will work fine with TBI. F body guys use them with good results.
Dont see why it wont work in a truck with a built TBI 350.
It has small plentium and runners so you should not loose any low end torque on the bottom and should pull hard all the way up the RPM band.
For the icing problem... Have you thought of using the heated TBI adapter plate from a early TBI 454? Should be able to find one in a wrecking yard.
You would need a square bore to spread bore adapter plate to bolt it up.

I've never experienced any issues with gas or even diesel for that matter, even on moose hunts in Fairbanks at -35F. I did once get a bad tank of diesel due to condensation in Chevrons holding tank. That can be taken care of with generous amounts of Heet as mentioned. With condensation, nothings going to help cuz the ice will plug your filter. You won't have an issue with it above zero though.

mine has a really large plenum. i have thought about milling it down 1.75" for better throttle response. i was thinking to the level of the top of the runners or a bit higher, look at the pic on the first page how high the pad is above the runners. it is a huge plenum.
:confused:THOUGHTS???? mill or keep the same height

yeah i have thought about it, but am not fond of the idea of stacking adapters.

Don't know what kind or quality of gas you had available to you. Around here it's all Ethanol blend and that **** sucks. If it's gonna sit some sort of stabilizer is needed.
