There were some tests that they did for Jeeps and trucks that were "confidential" and we were not allowed to talk about in public... The winter cold testing was insane!!!! (but I can't talk about that...)

I don't even know what kind of car, but we stored one in a freezer truck for someone when I worked at the cold storage. Not sure what the purpose was. That had to be around 1990. Was in there a month or more IIRC. I heard it wouldn't start when they got it out..

Hell yeah... Put a 4 bbl on that sucker... A good dual plane intake with a 600 vacuum secondary carb will run nicely....

360's were unappreciated for many years because they were "smog" motors... but if you build them to the same specs as the old 68 - 71 340's they run like raped apes....

Throw a set of 2.02" intakes on them and a nice cam and 4 bbl and they will run with a 340 all day long, if not beat it....


You can pick up an old 360 2 bbl engine real cheap... Now slap in a stock 340 cam (268/272 duration and .429"/.444" lift) or slightly larger, 2.02" intake valves, and a good dual plane intake and 4 bbl on them and you have a very affordable engine that will run great.... All 360's came with 1.88" intake valves...

No more cheap 360s around here. The la’s are all gone.
I will take the 360, clean it up and hope the thermoquad works as expected. New timing chain and thats about it. I should put the 340 intake i have on it. Wont matter though. It will be better than whats in it now. 87 hp factory, its probably 70.2 in its worn out state. And i sold it, to offset the budget 360 swap.

Mechanical fans are more efficient than electric ones...

But with the A/C on you need some extra air flow, that's why they put the electric fan in also...

I worked in climate control for 3 years and participated in some of the testing... They do alot of testing on the "cooling package" (radiator and condensor with fans, shrouds, and seals)...

Part of the testing is to pull 5000 pound trailers through Death Valley with the A/C cranked... Death Valley is so hard on cooling systems they have signs posted there to turn off your A/C so your engine doesn't overheat... Our testing was to put them through worst case, so they pulled max trailer loads with the A/C cranked to be sure that the engines did not overheat and the customer can remain comfortable with the A/C on...

Another test that they do is to park the car/truck with the front end one foot from a wall at the Arizona proving grounds and let it idle for 30 minutes or more... This makes sure that the fan, shroud, and front end seals do their job to make sure the air goes through the radiator and condensor and not around it... It's more severe than idling in traffic at a stop light... You don't get the ram air through the front end like when the car is moving and is the most severe test for idling...

People don't realize how much testing they do to make sure everything works properly...

However if someone modifies the parts from stock, and it overheats, they won't warranty it.... Like if someone puts an aftermarket grille on the car or truck and it overheats, they are on their own... If their aftermarket grill has more air restriction, then it can overheat easier... People don't think of that when they customize their cars... One of the challenges is to have enough opening in the grille to get more airflow through the condensor and radiator...

That's why they reduced the number of openings on the Grand Cherokee around 94 - 95... The old grille had 8 openings and the 'new and improved" grille had 7 openings, but they were a little larger.... That increased the front end airflow by 10% which helped lower the high side pressure through the A/C system....

They also changed the condensor tubes from round to star shaped... The star shaped tube had more surface area, which gave it more ability to transfer heat better...

Ok, I read that now. Thanks for waiting. :lol:
 
I would love to build two identical engines, one 340 and one 360 with identical components and put them in the same body style car with same gear ratio and tires and do an apples to apples comparison to which engine runs better with the good heads, intake, timing chain, and carb....

A true 340 vs 360 comparison...

That will be good in the Fargo...

You really don't need 2.02" intakes in the 360, but I like to do that since the good years of the 340 had them....

Back in High School, we had a 79 Warlock II 4x4 pick up as our tow vehicle for dad's Road Runner.... It was originally a 360 2 bbl with about 80,000 miles...

We pulled the engine and rebuilt it.... Hone, 9.0 compression pistons, file fit the rings to minimal gaps for less blow by, stock 1.88" intake valves with fresh valve job, 340 double roller timing chain, Crane 340 replacement cam, Rhoades lifters, Wiand dual plane intake, carter AFB, headers, Sonic Turbo mufflers, 2 1/4" exhaust exiting at 45° under the side steps...

It went from 9.2 MPG pulling a car on a trailer with the stock set up to 11.7 MPG with our mods...

It could get up and go.... We used to put the transfer case in 4 low and race the old 5.0 fox body Mustang GT's off the lights.... Our front bumper would be at the back of their fender at 45 MPH.... We were right on their door... They used to get pissed that a 4x4 pick-up truck could give them that hard of a run.... :mad:

We eventually sold it and the guy who bought it came back and told us about some of the things he did with it... He had a couple friends with Chevy trucks that used to give him a hard time about driving a Dodge.... They went 4x4ing one day and one of the Chevy's got stuck... He got out his tow strap and pulled the Chevy out of the mud easily with the Warlock... It put those Chevies to shame... After that his Chevy buddies never gave him a hard time about driving the Dodge.... Respect...

I would put the 340 intake on it... :thumbsup:
 
Stopped to take a break. Have 8 courses run .
I like the look better then the black top.
Just going to have to raise the edging when im done.
Had it set for the black top. Not a big deal.
 
Thinking of taking the Demon for groceries. Small town grocery store I like about 15 miles away. Beautiful day so far. Sun is very warm, partly cloudy, looking for 70 today.

Grocery getter. Why not.
 
Due to the leak issue that appears resolved, the stripes were rescheduled for the 28th. Cant wait. Demons need stripes.

Death Valley was about 70 miles north and hang a left from the house :lol:, when I lived in the old country. It wasn't uncommon for me to tell customers at the gas station who were concerned about summer desert temperatures and their traveling plans "Turn the AC off and roll down the windows. It will help cooling the engine if you turn the heater on while the windows are down also." Just past that left turn is this lovely stretch of road called Baker Grade. 900' elevation to 4100' in 19 miles 3% grade, no flat lands until the summit. There were 2 rest stops in the climb if I remember right, both had large water tanks for the overheated victims. On the plus side, it doesn't take much right foot action to descend a constant 3% grade and the fuel mileage is greatly extended :lol:.

Change the metal from black to ivory on 9 jars. How difficult could it be? :BangHead:
I gotta have some minimal standards even in arts and crafts.... The side strapping isn’t perfect, but the handles were chipping way too easy. Probably from people handling them. Ended up sanding ivory back off all the handles and repainting. Just put last coat on them. Also, started putting them together yesterday and she tells me I don’t have the glass seems lined up with the metal. :BangHead: Got them all repositioned. She will be putting these decals on. Names and date on one side bird pic on the other.
