I've had this 1966 440 for close to 20 years now in a few different cars with different cams, intakes etc.
I bought the engine way back when out of a 1966 New Yorker with 40k original miles.
The short block is bone stock, never touched, the original 516 heads are just lightly modded with bigger exhaust valves.
The engine used to be a beast running high 11's in my street/strip 4 speed Challenger showing a little air under the front tire a few times.
For about the last 3-4 years I was running the engine in my 1971 R/T Challenger and I honestly though the engine was on it's last leg.
It had a Six Pack setup on it with a MP .528 solid cam.
The engine was waay down on power, blowing smoke (and oil) out the tail pipes and badly fouling plugs.
I'm in the middle of a 440 Six Pack engine build for the wife's car so I was planning on limping it through this summer and pulling it for a rebuild next spring.
I removed the Six Pack setup to install on the wife's engine and discovered a major intake leak which was causing the engine to suck oil....a lot of oil!
I still expected the engine to be weak but I wanted to keep the car running and moving on it's own power so I installed my old faithful Torker II intake and an old Holley 4150 carb that I rebuilt.
On the advice of my engine builder I installed the paper gaskets, both sets, with valley tray.
That was no easy task and I can see why many get frustrated and give up on the paper gasket install as I was ready to but I was told a few tricks and got them installed without too much grief.
So today after chasing down some fuel leaks and building a custom fuel line and swapping in new plugs I finally got it running.
After tuning the carb a bit the test ride was a big surprise
It's certainly running on all 8 cylinders again, I had to tighten the rear view mirror as power shifting into 2nd made it flip up repeatedly.
I took it for a long drive and it ran better by the minute, no more smoke or oil blowing out the tail pipes.
It really runs strong, very snappy right off idle and pulls hard through the mid range.
With the 3.73 gear I was able to make the tire bark in 2nd and 3rd gear!
I'm not sure how long the engine will last but I'm sure glad it's back for now.
Six Pack ready to be removed.
The complete Six Pack setup was bought new and never gave me any problems but the engine ran like a slug compared to the way it used to run.
Once the intake was removed I discovered oil everywhere, it was puddled in the center of the valley tray, inside the head ports and dripping off the intake runners.
This install was the valley tray only with sealant applied around the ports and on the front and rear bars.
Took me quite some time to clean everything up for the Torker II intake.
What a mess
After a couple frustrating attempts to install both sets of paper gaskets, finally success, now I had to remove everything again to install sealer.
The beast is back, paper gaskets and all.
15 plus years ago the very same engine was banging gears at the track
