- If you've been around the channel for a while, you may be familiar with this story by now. It's a sweet big block powered classic Mopar. It's got lots of go-fast parts, and from certain angles it looks like it wants to be a drag racer. And yet the performance is best described as a little underwhelming. So today, let's take a look at Greg's 1966 Plymouth Belvedere II, and see if we can find some of that missing horsepower.
I'm going to state the obvious. That car is beautiful
A couple years ago I ran into almost this same issue with a friend of mines 400,after many hours of fiddling and tuning and still never running right we finally found from the information from all the specs of the engine when it was rebuilt that the compression only came out to just barely 8.0:1,and they had put a huge cam in it,and evidently they don't like that,because we put about a 3 or 4 sizes smaller cam in it and it ran great and cured all the bad running and tuning issues,ran like a totally different engine.... Not trying to say that's the issue with this Car,just something we ran into with that engine....low low compression with Huge cam= crappy running car lol. That is a beautiful Car!!!!👍
My friend Dave has a 67 Belvedere with a factory 426 Hemi radio and heat delete. Runs in the 10 second range!
Junk MSD box
“It’s so weird that the gas gauge works in this car” 😅😅 I feel your pain J.
I live @ mile high altitude and tuning is a low vacuum PITA. That car would be a nightmare here. My first delete for this car: get rid of that single plane intake asap for a any good dual plane. Sooo much better low RPM response and easier to tune, just me...........
I worked for Gabriel in the 90s. I was a picker (order filler). They produced Gabriel, Roadhandler, Hijackers, Duralast and other brands. The only difference between brands was the label and the box.
I added floor insulation under the carpet. 440 Headers make some heat. I failed to leave room for the gas pedal and my secondaries would not kick in and downshifting was sketchy. Bing the light came on 7/16" of insulation can do that. Now there is a hole in the insulation, and we are good again. We never overlook the obvious like is the fan turning in the right direction for engine rotation, mechanical or in the intended direction for electrical fans. I have a '71 Charger 440 with aluminum pullies and alternator brackets. I run the stock fan and a 3-core Champion radiator without a shroud, and it does well. Cars, never done.✌
That Belvedere in that color is BEYOND BEAUTIFUL.
My uncle still owns his 66 Belvedere he bought new in 1966 in Oakland, California. In fact his neighbors ran the Melrose missile car that owned the Dodge Chrysler dealer in Oakland about 10 years ago. My uncle restored his Belvedere with the same British racing green, color he once had, originally had a 383 police package car manual. He decided to put a modern 6.1 hemi boarded out to a true 426….
That is a simply GORGEOUS color!
I have picked up so much knowledge watching your videos and I have been working on cars for over 35 years. Thank you for that!

Really knowledgeable in depth diagnosis on a very deserving mopar.
Have always loved the 66-7 B bodies. However the 66 Coronet 500 is my favorite. Buddy had one. Console and buckets. Black interior with white seats. Gorgeous car. Color was kind of a champaign goldish. Very pretty. Had a 361. We put manifold, afb off of a 64 383. Always thought the 361 had more in it than we were able to coax. But alas kids experimenting.
the rectalanguitive exhaust ports mimic the rectalongical design of everything else on the car. I've never noticed how well done the instrument cluster is on these cars. The body work on these later 60s B bodies always looks high quality, a real step up over the earlier cars.
That is one beautiful Belvedere. You get to work on and drive some really nice cars! Loved the way you were troubleshooting that accelerator cable linkage too.
Outstanding car! Bet she turns a lot of heads!!👍👍❤️
That paint looks like candy. Absolutely beautiful
I absolutely love that car and I like yourself, I usually only like the factory interiors but that one is done very tastefully. You did a great job tuning that thing looked seriously quick
