Most Under-Performing Musclecar Ever Produced?

[W J]

A friend bought a brand new 1964 Corvette Midnight Blue/blk int. fastback coupe w/327 365hp (single Holley w/solid lifters & good cam), close ratio Muncie 4 sp, w/4.10 posi rear....pretty sure the car cost less than $6k. The Vette w/that powertrain combo was a screamer-- there wasn't much of anything Detroit built and street-legal that could touch it in '64-5 ....that's my pick for over-performer.....As far as poor performing muscle, I'd have to pick any of the cross-fire fuel injection Corvette models, along with the crossfire injected Camaros.Think they were 1982-1984 vintage and both were very disappointing....

The bad thing about the 69' Boss 429, if anything went wrong with the internals, you were screwed, it was a fortune to repair.
I'll throw in a 1970 Pontiac GTO 400/350HP.
I had one. A 3700lb. pig with an 'Endura' bumper.
Somewhat pretty, but it went 'nowhere fast'

In the hands of the general public most anything with multiple carbs was usually a slug.

Buddy of mine used to have an L-88 Vette that I could roast at any time with a 340 Dart.

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 Now, with NHRA allowed superseded parts (block, heads, ,oil pan, intake, carb), it's super fast!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.

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.

I could be mistaken, but think some of these cars were made to be pretty good 1/4 mi. performers and are worth some pretty serious $$ these days...?? Anyone? WJ
