Awesome! Way to "represent"!

RonnieB883,

Dan's fuel line mod, and a heat deflector under the carb sure help on the heat soaks. After shut off on these hot summer days after shut down I leave my two electric fans active (I have a manual over-ride switch under the dash and temp switch in the radiator) to cool down the intake and carb. Even on my old worn stock engine, hot starts are never a problem and it's starts immediately!

Hey, Ted. I'd read Dan's fuel mod awhile back but that was back in the Spring and cooler. I may revisit it.... I made an aluminum heat shield but never put it on - lazy. Not like the car won't start anyway, just takes a couple of extra turns... Now, the Roadrunner was a Hot Starting MESS! I think I've repressed how much of a pain it was fixing that problem.... Starter wrap, fuel line wrap, adding an electrical fan and using it like yours, less advance vacuum canister, bigger aluminum radiator.. The list goes on..... Overheating wound up killing that 383 but the new engine (440) stays 190-200 degrees..

New Challenger... House sitting for a friend and I've been driving her Challenger for a couple of days. 2012 3.6L 6 cylinder, 305 HP. I'm impressed! Well, I probably should be since I drive the Demon everyday. 40+ years of engineering improvements are very obvious and this car, even with a V6, gets up n goes! Only sad note is the Challenger has become a commonplace vehicle. I see them everywhere and nobody honks or waves, rolls their windows down to hear the exhaust, or really pays the car much attention. Is it really because the car is not HEMI motivated?! Engine and performance comparison to my car though, another story! In every category, the Challenger performs better. I think people who swap newer motors into older cars might be on to something! Regardless, I'm still gonna leave the "can't kill it 100 hp Slant monster" in the Demon and cruise on by in style...

True,... The newer cars are very nice... Definitely more comfy...

But then you can't say, "I built it myself".

Oh yeah, and it's nice only spedning about 1/10th of the cost for an older A body too.

Rob,

Agreed!

There is something to say for having a car paid for and no monthly payments!

Ronnie,

Sounds like the blocks have accumulated some rust/debris reducing the water flow or they are built to the hilt to get that warm.
I have two 440 cars (69 Chrysler 300 with a HP motor and a 72 Imperial) and they run right at 180 which is the stat I installed. I always keep them filled up with 50/50 antifreeze and have kept the stock style clutch fans and shrouds. I know some owners that don't and they have all kinds of overheating problems.

Hope you get over heating issues sorted out.

I'd given up awhile back on getting a new tail panel from AMD. It was on backorder and not expected for 5 months.. I'd resigned to fixing it myself and thought they'd given me my money back. Well, I came home the other day and lo' and behold, a big box is sitting on the porch. Score! A new tail panel to fix my broke-ass one. Good quality looking piece too.... Bring on the spot-weld drill bit!

Awesome!

I am getting two rear quarter panels from AMD for the 74 soon.

Decided to roll home in the Demon again this year. Makes three years in a row that I've driven home for the Holidays in a old Mopar.... And, this'll be the third trip home in a year (6000 miles)! Looking forward to it and wave if you see me!

Ted,

Let us know how the quarter panels work out. (Quality of sheet meta, ease of installation, etc.)

Got back in town last night. 2200 miles total and averaged 22 mpg... Electric fuel pump acted up a couple of times on the way down, like it just lost prime and wouldn't pump.. Replaced and no problems since. Actually, the car seems to run better after the pump replacement. Think it was either higher puel pressure or that the new pump puts out a more consistent flow of fuel.. Girlfriend (and her 200 lbs of luggage! lol) flew down and rode back with me. Car rode fine but struggled on those long hills. I would get a run going downhill, about 70mph and be going uphill and geting deeper into the throttle to try to keep speed up but the car would slow down regardless. Didn't matter if I mashed the pedal to the floor, I'd settle to a constant 50-55 mph and wouldn't pick up any speed til cresting the hill. Is this a jetting problem? maybe just a slant six 100 hp problem?

RonnieB883,

No, it's not a SL6 problem. Sounds like you need a tune up and valve relash.
If you increased the compression ratio it would give you more torque to get over the hills.
Are you still running the one barrel? If so, what jet is in it....? Too small of a jet can be limiting if you don't have a dual plunger power valve atomizer body in the carb. My 1920 Holley has that style so it helps a little when you have a small jet, floored going over a mountain pass. More compression and a bigger jet (#62-#64) can make it feel like a 318 with a 2 barrel.
If your still running the 1945 Holley, jet up..
You might like the added performance of a two barrel Super Six setup. I pull a 19' boat with mine. Also towed my son's race truck home several times with the Dart. More compression really makes a huge difference.

Thanks for the reply, Ted. I've always been suspect of the 1945 Holley that's been on it from the start. I dont' have any experience with the 1920 or two-barrels and the 1945, though quirky, gets me anywhere with decent mpg.. Jet in the 1945 is a #63 and I have seen alot of #60-61 talk on here. I figured #63 be fine with the 10% ethanol blends... Of note, no ethanol gas runs the same.. All plugs always come out looking perfect. I've really considered milling .090 off the heads for a compression bump; might do that before giving the lil beast to my son. Valve lash is definitely due - though it's not ticking or sounding any different.. hmm... open for suggestion, ready to tinker..

Ronnie,

I relashed my valves a few weeks ago.....it was getting too quiet after 3 years of hard driving. Now there is a nice even clatter under the hood again, but not too loud. Several intake valves were at .008, a little tight. Nothing too far out though. All the exhaust valves were at .020.

Doc is always talking about the merits of a little more seat time helping low end torque. So I went with a little more lash, .011 on the intakes and .022 on the exhaust. That provided a big jump in low end torque at low rpms (below 2000 rpm which is 50 mph) and much better vacuum reading across the board. It gets better mileage since I do not have to push it as hard. With the added compression from the wider lash it feels like it has picked up a little more power.....

So maybe running the #63 jet (which is a good idea) and a relash you will be back up to 25 mpg. Your right, each load of gas has been interesting. Not very consistent on the mixture........
