Thread: 327 cross-ram webers

Tweet

Just wondered if anyone has experience of setting up 45DCOE Webers on a (Moon-style) cross-ram manifold?

First, the engine: it will be a close-to-stock mid-1960's 327 Chevy with 365hp, as fitted to Corvettes of that era. I will probably fit a solid-lifter bumpstick that is a modern equivalent of that old cam. Compression will drop to around 10:1. It will be pulling a 3.07 or 3.31 axle through the Muncie M21 4-speed.

I have an original Iso Rivolta cross-ram manifold designed by Bizzarriniin in Italy (later copied by Moon and others, I believe), except it has a housing on top containing the twin throttle shafts that are geared together and run in ball-bearing races. It came with 4 45DCOE carbs (152 suffix) which were the size originally used by Iso & Bizzarrini. It came to me with no main jets at all.

I would like to know a starting-point for setting these up with this engine as regards venturi size, auxiliary venturi size, main jets & emulsion tubes, idle jets etc. It will be in a street Iso Rivolta GT 2-door coupe fo 1966 vintage. Not a race car!

Anyone got any ideas? I do have a couple of books on Webers, so should understand what you are telling me.

Thanks,
Chris
