Most Under-Performing Musclecar Ever Produced?

[Jeff Lee]

Hmmm...how about the '67 Mustang 390? What a pig. Now, with NHRA allowed superseded parts (block, heads, ,oil pan, intake, carb), it's super fast!
And when I see a '69 Mach 1 cross the auction blocks with (big bold advertising!) a 390 under the hood for big bucks, I want to yell...sucker!

And I would gladly race a stock '68-'69 340 Dart with a 4-speed and 3.91's against a stock '66 Chevy II 327/350 with 3.73's. I think it would all depend on who was driving.

383 Road Runners were not as quick as the road runner itself.

Back in the late 70s I had a girlfriend who bought a 68 383 R Runner from her aunt for $500. I used it to tow my car to the track sometimes, it was very quick I thought and had a 3.55 rear. The motor was untouched with old plugs, wires, exhaust, stock vacuum dist, AVS and air cleaner. I finally got it down the track one day for fun and it ran 14.20s with zero effort. Paul.

My new 1965 Plymouth 426 Street wedge was a turd against the GTO's in 1965. It was just an over grown 383.

Even worse, it was an over grown 361/305. Same style mani, same carb, cam and heads, although the heads had different casting nos. I had a stock 426/365 64 Ply back in 73. When I added a TM7, 4779 Holley and 59 dollar headers it ran 12.90s,13.34 with a dual plane Edelbrock, so as bad as the heads and cam were they far from the biggest problem. With a borrowed 6 Pak some pocket porting and a stock 426 STG1 cam it ran a best of 12.28 with the stock 12" conv still in place.

I had one of those 454 SS trucks in my shop not long ago, the owner had taken very good care of it through the years, and I was even surprised how big a turd it was. I say surprised because I knew real well how big a turd the 454 throttle body engine was, but I thought it might be OK in a 1/2 ton pickup, and the darn things even had a 3:73 gear with a regular 400 tranny too. Sick!
I thought those 340 six-packs ran pretty good, but I never got to drive one. Were they much better than a single four 340?

I'd have to say the 1980-81 Turbo Trans Am was the most pathetic excuse for a performance car from the factory although the Boss 429 cars weren't very quick for what they were.
