I think that getting oil is a good idea to getting the intake manifold warmed up. But it's going to take a long time. As soon as the air vents open up, more air is going to pass over the running tubes and manifold. The fan is sucking in cold air "over" each tube and the manifold. So there is a condensing affect taking place.So if one could insulate the running tubes and the manifold and add enough heat to the manifold..its done. Getting warm air for intial start up is even better.

With a standard carb set up the original air intake was pointing to the left bank cyclinder head just were the air comes out from below the oil cooler..this is where some of the warm air was sucked in originally.

I am not certain what side is the hottest though due to the rotation of the fan..but it must be the left side if GM had the air cleaner snorkel snout pointed in that direction.

Just my two cent.

I like the idea of losing those FOUR pesky Rochesters and all that messy linkage in favor of a single, time-testing Holley 390. Even simpler than a pair of 2bbls!

I was a little surprised my 12v pipe wrap heater idea didn't even get one response. It would work even better with thermostatic control to automatically turn it on/off based on the ambient air temperature at/near the point where the air enters the carb. I'd place the sensor in an air intake snorkel to get the most accurate reading.
Perceived advantages over the oil type pre-heater:
* Faster pre-heating? for better performance at low temps.
* Better performance at warm/hot temps.
* No risk of oil leaks.

It would be interesting to see how well such a setup works. Doubt it will be me, though...

Have seen the Engineering manifold before but only in a two barrel intake with a oil chamber in the rear of the Intake like shown. Have seen some with a small oil chamber also welded to the lower plenum as suggested. Thinking a better answer would be the use of heat riser off a 84-87 Buick. Also for a two barrel but thinking it would work with 4 barrel adaptor.

I was really thinking about this last night and the idea about the oil is great. But I was also thinking about using glow plugs? I see that they come in all sizes but I dont know much about them.. Wouldnt they work? They are basicly heaters!!

But they'll burn out quickly if left on...and would ignite the fuel / air mix, if in the airstream!

Updating an old post - I'd plug one manifold port, fill chamber with oil, and insert a small 12V heating element in other port to keep the oil warm. The idea being that it would work like an oil-filled radiant heater but on a smaller scale.

Otherwise, I'd use exhaust gas tapped off of the exhaust pipes, like an air-cooled VW.

I know this an old thread, but where does the oil go ? after it goes in the box? Is it recirculated back in to the motor ??

Yes... It's in the Oil Cooler circuit of the engine.

I wonder if a section of runner pipe could be modified so that another slightly larger pipe be welded to it creating a cavity which the hot oil could be plumbed into and out of the runner. Yes it would have to be done for each runner but they could all be tied together to avoid too many oil lines. Maybe adding some insulating material to the runner cavity along with the oil mod to the plenum. Not sure if the benefit would be worth the effort.

Wouldn't something like these work more easily and without any major modifications? You wouldn't have to mod the oil filter outlet and could easily move the 4 barrel and manifold to another car.

I'm thinking of giving something like this a try. Reading the KeeNovo comments, it appears you can order the 12v heating pad in several shape\sizes, with a more or less permanent glue back and thermostatically controlled. Temps seem to be any where from 100F to 160F, maybe more. I would think 100F would be sufficient, placed on the bottom of the main manifold \ adapter body and the manifold legs would still heat up from the head

All you can do is try one.... I'd go with the 120 watt..self adhesive.
