I am throwing this in single tank section since I think it would be of most interest for single tank converions.  Well, it seems you can't buy engine blankets anymore.  I expect that people have forgotten to take these off of their cars and then ran the car resulting in either the blanket being pulled into the radiator fan, or the blanket even catching on fire.  So in this litigous age these products are hard to come by.  Looks like I will have to build my own.

I've acquired an old sleeping bag and thinking of using that.  I've thought of using spray adhesive and sandwiching between space blankets.  I've thought about getting an expensive sleeping bag rated for arctic.  I've to 6 cyl merc and the crosspipe and instake uptop are pretty hot, but I don't think it would pose an issue.  The exhaust is low enough that I don't think it will be an issue.  My merc has plastic bottom plates that help seal up the bottom, so I think if I seal up the top with blanket I should be good.  Running with grill blocked for the winter so i will insulate the cardboard some.  I'll just fold up the engine facing side and throw in a plastic bag and put in my trunk when not in use.

Anyone have some better ideas for a blanket? I plan to tape a piece of paper over the ignition before puttting blanket in place, lest I run the car with the blanket in place.  It would be nice to have something that could take operating heat (really nice), in case I still somehow forget and run the car with blanket in place.  I think it can keep clear of the main fan.  It would be really nice in cold weather to be able to run it with the extra piece of insulation in place.  In theory I could try to insert something behind the current hood insulation, but it would have to be able to take moisture exposure and not trap moisture against the backside of the hood.
Any ideas?  Anyone?

Well I made one.  Took old sleeping bag cut up to cover the engine with the hood still shutting (about 4 layers) and then used spray adhesive and sandwiched it with a space blanket.  It looks cool and helps.  I did not trim the space blanket as it still provides some help over the parts where the insulation is too thick.  Helps keep it from sucking into my fan when I forget to take the blanket off.  Froze up today despite it.  I believe my fuel lines had too thick a fuel.  Posted details on Elsbett conversion thread above this one.

From Elsbett conversion thread above this one:
"I had taken to running the car with the engine blanket on when below freezing for the high temp of the day.  Car does not overheat and its easier.  I just noticed a little tear in the space blanket and a bit of smoldered sleeping bag.  My guess is this was the injection line heaters.  The space blanket material could take the heat.  Just got torn a little.  I had been getting pretty lazy with the blanket and running when the high was 40-45.  The engine would hit close to 100 C at some points.  I am backing off on using the blanket while driving for now.  For next year I may see if I can find a less flammable insulation.  You don't want the blanket catching fire while driving down the road!  It has been a fantastic addition."
