I think that I can break it in with the two fours. They need to run 1:1 not progressive and the carbs may need to have different metering rods installed. Still checking.

The Factory offered dual quads in the late 50's Vettes and the 57 Chevy (I think) and these were on 283s so I believe the 283 with the 2x4s will be ok. Its a nearly stock build though with a 10/10 under crank and 30 over flattop pistons. All ARP hardware and the other internals are high end. The heads are Powerpak with milled bosses, screw in studs and guide plates with stainless valves, hardened seats and new guides and viton seals. Also running roller rockers. The lifters are hydraulic and I have a moderate lift Erson cam.

Had forgotten, but when I fired up the 302 in my 69Z after that build, I was running a Smokey SY1 crossram and a single quad 850 CFM carb. That was a finicky set up but we fired her, got her to 2000 RPMs and let her Stella in. Motor ran fine.

Just older now and worry more

What exact manifold is in question?
