Warm up tips
Well now that its freezing here its time to think of a way to get my warmup time to be cut down a little. I have an offy dp and holley 390. The only way that ive been told i can have the intake warm up faster is by making the "bake oven" system that cam stock on my 82' But i now dont have all of that piping b/c I threw it all away so now im left with nothing. So, is there anyone that has some sort of setup to cut warm up time at all? I dont have access to a outside electrical socket to put a engine warmer in there or anything.

Ever contact clifford performance about a heated spacer? They used to sell them.
I've heard of welding a small aluminum box to the underside of the intake, with an in and out fitting, then tie this in with the heater hose, that runs to your heater core.
Another thought, get ahold of an egr plate used on four barrel trucks, see what you can create.
There is the shroud idea, take a strong yet thin material, basically, lay it over the air filter and mold it down/around the exhaust manifold/header(s) so the warm air off the exh. manifold/header(s), is drawn into the carb.

Now I use 5-30, get a block heater, and a rad cover. Unless you have the rad cover, if you drive in excess of 100km/hr the coolant gauge, not sure how reliable it is indicates cooling. Keep your heater blower in the cab down to a minimum as well whenever possible. Not sure, but mabey you can make or get a restrictor for the radiator coolant hose but not sure if the water pump would like it. Wonder is just diabling the egr in the colder months will help as well?

I cant get the engine block heater b/c i live in the upper level of a condo and dont have any electrical outlets outside and neighbors all suck and wouldnt let me run an extention cord. I never put the ehater motor on until the truck is warmd up after 20 mins haha. I think im going to call clifford today and see what they have. And now that I have a header the baked oven idea is kinda out of the window. IM not too sure of what else I could do? Do the 300's have a engine block heater made for them?

I say replace the intake manifold with Clifford's. They've got one with the coolant passages. Just hook it inline with your heater hose. It's rarely freezing here in Alabama, but in 30s and 40s, my Holley 390 and Clifford intake warm the truck nicely in no time. No more starting the truck before I get in the shower on those cold mornings!

I bought a engine block heater @ Napa for $19.95. Drained the coolant and pulled a freeze plug on the drivers side under the manifold, first plug. Keep the electric cord away form the manifold. I plug it into a timer for 5 a.m. head to work at 7:30, truck starts right up hot air to defost windshield, after a couple of minutes she drives off warmed up with no hesitation, it's a 1979 F150 300 6cy 4x4.

I have had a few 300's over the years in the cool climes of PA and Maine. But I am only now doing a 390/Offy set up. Before I install the motor and while it is still on the engine stand, I mocked up a cardboard version of the old heat stove except it is larger and covers both exhaust manifolds. I added a rounded section to connect to the air cleaner intake. I'll have a local metal shop do the fabrication out of a heavier sheet metal. I also included mounting tabs to the intake and exhaust mounting bolts. If it appears weak, I'll add something later fore and aft. Given the other sheet metal work I've had done in the area, I'm guessing this will cost about $50-$75.
I was also thinking of having a plate extending about 1"+/- below the bottom of the Offy intake where the old style exhaust would have bolted up and will have two nipples to accept in and out heater hose. I'd be interested in hearing from anyone else who has done this and how well it has worked.
Thanks,
John

Not long after I got my 79F100 I desmogged it (no smog police in Mississippi !)
I junked the factory back-draft air cleaner set-up and replaced it with an aftermarket non-restrictive one. Usually this gave me no problems, and the mileage picked up a little.
However, once the temp got down to 35F or lower (which happens a few time during our two months of winter), the carburetor would ice up about halfway in my 54-mile commute home. No fun. I finally resurrected the old factory air cleaner and reinstalled the hot air intake. Problem solved.
That my .02 worth.
