The omp lines into the inlet manifold, will this work

seen it done many times but don't really know how well it works. to me it's the wrong place. that area below the throttle blades sees constant vacuum and would be sucking in more oil than needed and producing lots of smoke. they really should be placed above the throttle blades like they are in the original carb, thru the side of the carb body where it drips down into the in coming air stream. i think the rate is something like 3cc/min at 3k rpm. if this is wrong someone will correct me. it's easy on the holley. plumbed into the primary bowl via the level site plug location with a barb fitting.
