engine block heaters for race cars?

[Super Coupe]

I just put a bucket under mine and slipped he hose back some. Drained about a gallon filled it up with antifreeze and ran it for a bit. Done.

Ill go ahead and back the rockers off too to keep pressure off the valve springs while sitting a few months.

Can you not just cycle in some anti-freeze for storage, then flush it out to go racing?

Seriously you're making this harder than it needs to be, save yourself the time, money and hassle with jacking with some rigged up shit.
Drain the water, put in shop.
When you get ready to go racing again fill with water, turn the water pump on, stick the tip of a air nozzle in the radiator opening, wrap with shop rag and give it one or two short blast of air and that will get rid of your air pocket in the system.
Be sure to wrap with shop rag or you will get sprayed with water, trust me.

that is a hassle and there can't be a trace a of A/F in the system or even smell of it.

drain and flush might have to happen 3 times over a 2 month period. I don't have time for that because like I said, it takes FOREVER to burp air from the systems on these cars.

As for making it harder....I'm actually trying to make it as effortless as possible like plug it in and leave it on a thermostatic switch. Walk in shop, unplug, load car and go to track...bring car back to shop, unload, plug in and go home.

I am leaning toward the lower radiator hose heater and just need to find a way to control it based on temperature.

There are others out there not just snap-on. I had to use it on diesels and other cars/trucks due to extended purge times/overheating. Sucks a vacuum on the system, has a valve and hose on the opposite end of the venturi to refill with 5 gallon bucket full of distilled water to use. No fuss no muss.

Easiest thing would be drain the water, yet your not up for that due to difficulty of evac the air.

I would use a freeze plug style, but you'll have to drain the water.

I looked into this stuff back when I was racing with alky and did not want to use so much fuel to warm up before a race, but I ended up cheating with fuel maps/temps.

this works

We used drop lights with 100w bulbs for boats in storage. Put them on a timer to run 12 hrs during the night.

If you had some circulation a fish tank heater would work. Really though any kind of space heater, drop light or any cheap lamp you can stand next to it. You don't need to warm it up much, just keep the area above freezing. You'd be surprised how much heat light bulbs can generate in an enclosed area.

They have a quick connect insert that you plumb into place in the radiator hose. Easiest way to handle it without having to constantly drain. With water only and all the dissimilar metals I'd worry about corrosion in the system.

I'm glad it doesn't matter if we run AF. I always try and run some to keep the cooling system from getting Dirty.
