Default 1967 Corvette 427 Roadster Is a Big Deal



Horsepower wars were in full swing in the '60s, and getting one horsepower per cubic inch was a pretty big deal.

Therefore I guess they really weren't messing around, putting out a 396 with 425hp! Deferring this achievement to the 427, must have gotten past a few!

435 minus 427 is 8.
425 minus 427 is -2.
450 minus 427 is 23 hp, should have kept it!

425 minus 396 is 29 hp!

375 minus 327 is Wow!

Roadsters have side curtains. Convertibles have roll up windows.

That makes this car very very rare. A '67 Corvette with side curtains.
