327/365HP?

[Tbird]

Besides the tachometer redline differences on a '64 Vette with a 327/365 HP engine, is there any other thing one would look for that would represent this horsepower engine was born to the car? Of course I do know that the engine numbers would validate this.
Thanks,

You will also have a Holly carb, and mechanical lifters with the 365HP version. Another thing to look for is the diameter of the exhaust manifold's and exhaust pipes, they should be 2 1/2" vrs the 2" that are seen in the low HP versions. Not much to work on but to ID properly, you must not only look for one item, but rather an assortment of different things that sometimes make the identification easier.

I thank you. That is what I thought and had read. I appreciate your quick response.

A few small clarifications
The 300 HP motor had the 2.5" manifolds in both '64 and '65 and the 350HP motor had the 2.5" manifolds in '65. '65 350HP motor also had the holley carb in '65. That last sentence above is right on!

Brian,

One more clarification, when I mentioned low horsepower, I was referring to the 250 HP version.

I think they had a return line to the tank for the FI.

Thank you all...this one has the 6500 Tach, however it is NOM. Charles

No midyear had a return line to the tank; return lines didn't start until the C3 era with Q-Jet carbs.

My Mistake. I thought the fuelly cars required a return line.:confused

John, as usual, is correct. I have an original fuelie unit in my basement...no return line.
