Making one at the moment for 4 new 97's on a Vintage speed inline manifold on a 276 Desoto hemi. Just waiting for the lever arms to arrive. I will make the rods and shaft collars from stainless steel. I intend to have both outboard carbs starting once the two inners have reached 50% throttle then the two outers with go from nothing to full open in the last half of the throttle stroke. I did this on my triple Rochesters on my SBC and it works great. Peter
I have just ordered a deluxe linkage from Charlie Price which is not progressive but hopefully a good starting point. I'd be keen to see how yours turns out. Thanks, John
Somewhere i had a pic of a wieand 2x4 with the 4 barrel to 2x2 adaptors with 4 97s in a row with linkage but cant find it.
