Fuel Delivery
« on: October 07, 2023, 10:43:48 AM »
I understand that Chevy always wanted the Corvette to have the highest horsepower ratings when compared to their other vehicles, and that Corvette was considered to be a sports car.  I find it interesting that Chevy was using somewhat "exotic" fuel injection and multi carb set ups in Corvettes in the 50's and 60's. Fuel injection in the Corvettes stopped in 1965 when big blocks started, and Chevy started using tri power carbs in the higher horsepower big blocks from '67 to '69.  Is horsepower rating the only reason that first gen Camaros were never factory delivered with some type of multi carb system?

Chevy did consider a 3 x 2 option for the SS350 in 1967. Did not make production but got close as a few 0-casting manifolds are known to exist.

Lots of speculation as to why it did not make production; too expensive, low projected sales, didn't make power.

This original manifold survived and still lives on a 69 camaro.

I believe Zora was a proponent of maximizing the lighter SBC, making a more balanced vehicle. Eventually, he relented to the BBC.
Other than the AIM, I've not seen documentation about the 67 L70 opttion.....
