anyone ever flow test 383 A body manifolds say vs 383-440 hp manifolds

I would love to see actual flow numbers on the stock A Body manifolds and B Body manifolds. I thought someone would have already done this.

Based on my personal experience with "absolutely" no real evidence, Short of strip time. The A-body manifolds flow near as well in 69 as the SB an RR B-Body HP's did.

The difference is negligible When you reduce the weight. A-bodies had the same cam the RR and SB packages had in the 383 versions! JMO!
