Block heater to help with cold starts?

Hey everyone,

Has anyone ever used a block heater to help a cold blooded engine heat up faster? I'm talking about using it for 40-50 degree temps so it starts a little easier and gets some heat in the engine faster.

I have a 383 with an air gap intake and a 950 DP without a choke.

You don't need quicker heat in the engine, you need heat in the intake right under the carb. They make various oil pan heaters. Here's one of many styles. Fasten it under the plenum.

I think your right, if the intake was heated up it would start up a lot easier. I'm thinking something like a silicone heating pad, with a piece of high temp foam to make good contact between the pad and the intake.

I have one of these on my little diesel tractor - works just fine or I wouldn't get it started in the winter at 32 F or (usually) less : https://www.wolverineheater.com/Engi...ars-s/1814.htm

Yup those Wolverine heaters are awesome, Dave.

We live in, or at least very close to "DUAL Block Heater Land".
I had an old 390 Ford with dual 600W immersion heaters that came in very handy at -40 (Celsius or Farenheit ... same temp when you get that cold.)

I got in the habit of plugging in after an extended cold stretch, and noticed that when the weather warmed up to the thawing point (0C / 32F) ... that I had heat very quickly.

Up north (Northern Alberta, Sask, Manitoba, and NWT, they simply leave their diesel engines run 24/7.
Gas jobs get the dual block heater and Wolverine pan heater treatment to warm the engine oil. You can only imagine how thick 5w30 can get at -50C.

Many years ago, I learned that when making a decision between an oil heater and a water jacket heater, use the water heater. Oil does not transfer heat as well as water.
Not having lived in freezing temps for over 40 years, I was not aware that there are such things as manifold heaters, but that looks to be the best answer. Well, actually the best answer would be to move South.

engine heater.

Even when we go south (NOT far enough south) for the winter my Ford 7.3 diesel has to have the block heater on most of the time for an easy start.

cold starts

I grew up in Montana and the block heater is the best for cold weather - instant heat to your heater core - quicker oil lub to the engine and all parts of the engine receive the benefit of the heated water because of the circulation in the block - just my thoughts - jaxx
