Default High Performance Engine ???

Did the 1964 Corvette have what is known as a "High Performance Engine" ? Some search sites ask this question and I don't know how to answer them. Thanks for the responses in advance

Yes, you could order a 327 engine with a solid lifter cam rated at 365hp (carb) or 375hp (FI).

The '64 Corvette was a high performance car. The whole package. Some engines were hotter than others, but all were high performance to some degree in that era.

And, the example you're showing came out of a '64 Corvette. It's a 327 cu in / 300 hp engine that had a 4 barrel carburetor and a manual transmission. Engine was assembled on January 30, 1964.

Zora's quote, from the 1961 recording:

“You just took a ride in 1961 Corvette. This car was powered with 315 horsepower, fuel-injected engine. This car has performance engine. Actually all Corvettes are high-performance cars. The difference is only in degree.”

The four available 1964 Corvette engines, all 327 CID, with name and RPO number:

250 HP "base" or "standard" (part of standard equipment)

300 HP "High Performance" RPO L-75

365 HP "Special High Performance" RPO L-76

375 HP "Fuel Injection" RPO L-84

There were a total of 14 different two letter assembly codes depending on transmission type, and with or without air conditioning. Details are in the NCRS Corvette Specification Guide

I am very happy to have hit the nail on the head 60 years later! Very well stated and my point, exactly.

We agree on a lot but not on a 250hp engine in a vette.
That was for the ladies to drive. Even a a 64 Pontiac lead sled
Catalina could be ordered with more than 250 hp. ( although
you could order a 2 barrel 230 hp.) Yes, a 64 Corvette offered
high performance engines, a 250 hp was not considered high
performance in the day and still is not.

40 years ago when we worked on a fair share of AMC cars, we joked that AMC stood for All Makes of Cars or All Most a Car. Kidding aside, for an independent, they did just fine and my hat is off to them. That is an America I wish still existed. Underdogs having a go at it. None of this woke crap. Now, back to your regular PC programming..........
