Most Under-Performing Musclecar Ever Produced?
 

Based on cost, could it have been the 1969 Boss 429 Mustang.

And the later model mod-motor CJ Mustangs before they got blowers. Made less power on my chassis dyno than my stock '97 Chevy pickup.

Back in 69-70 , I remember a Boss 429 sitting outside DYNOTECH in Ridgewood , N.Y. Motor was never in car. After months going by I stopped and asked what ever happened to the mustang and they said the owner had broken the motor and the parts were extremely tough to get and the owner ran out of money / and or patience. They said he could have gone across the street to Meyer Chevy and bought a new car for what it cost to build a modified Boss 429. ----Never seen or heard one run !!!----John

I have to say, as a swedish kid, it's great to browse this forum. I'm learning something each time I go here.

Let me ask the opposite. What would you guys say were the BEST performing car for the money back in the day? 396 Nova?

Re: Most Under-Performing Musclecar Ever Produced?
 

Best Muscle car...Z/28 Camaro....or any Hi Perf. Small Block Corvette.....Most Big Blocks were nose heavy, spun the tires easily and handled poorly. I preferred any fast-high revving small block.......

For the money? Probably the 66 Chevy II 327/350HP 4 speed. Especially given the tire technology of the time.

2X on the 327/350 HP Chevy II - The best bang for the buck back in the day!

Bill ( Grumpy ) Jenkins thought those Chevy II 's with the 327/350 combination ran good too!

Re: Most Under-Performing Musclecar Ever Produced?
 

The '66 327/350 was hands down the fastest ever - only weighed 2800 pounds

Back in the day of real street racing it was king no matter who had it

My brother had one (got stolen 3 times and the insurance company said don't buy another one)

With a 3.73 gear it felt like the engine was going to pull the steering wheel out the front of the car along with the engine

I know this is not what this thread is about but with first hand experience I had to say - I would still like one

As far as the factory slugs went , the street Hemi cars were no fun to own. If you were not mechanically inclined it was not much of a street cruiser. A plug eating, oil burning detuned race motor. BUT, Love it and a lot of TLC and some mods , it was a bear. The 6 pack wedge motors were usually faster on the street at a lot less cost.
