Yeah, I do on pretty much any non boosted/nitrous mopar combo unless I'm trying to kill some torque through the middle or they are exhaust restricted. The only carburetted street Motors I've ever worked on that seem to run better on wider spreads and Late ICLs are Bb Buicks, Bb chevys and many small block fords. Some small tire A body big block cars back in the day actually with a 110-112 split because they wouldn't hook on the shift recovery. Buicks seem to run best really wide like 114, I think it must have something more to do with the fuel delivery/distribution through the manifold getting upset with large overlaps.

When the cubes get Big ( like over 580) you pretty much have to go wider since the running ramps have to be big enough to get the big motors to RPM at all.
