Most Under-Performing Musclecar Ever Produced?

[X-TECH MAN]

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.
