I haven't yet unboxed it, but I'll be installing it in the upcoming weeks.

I don't even have a Vette yet and I want to run out and buy one of these.. lol

I've been collecting parts, and honestly, a little lazy during my vacation.
I've only installed the throttle valve linkage for my 200-4R transmission.
I'll start teardown today and document the installation for a separate thread.

You'll need a L88 hood to get the Edelbrock to fit. I have the Proflo 3 on my 66 427. I love it but it likes vacuum; hopefully your cam makes at least 8 at idle.

I'm currently running an Edelbrock 2701 with their 1406 carb under my stock '77 hood.
Edelbrock tells me that the Pro-Flo 4 is actually .690 shorter than my current setup.

Sounds like you're in good shape then. Your 77 must have more space under the hood than the chrome bumper C3s.

I don’t know what intake would go best with the TBI but I think for my engine with a few issues TBI is a safer route. I may have to switch cams to get a better combo with the intake or port injection. I’ll go back to the mechanic to discuss.
