best mechanical pump for high hp small block

Recently I needed a good high perf. pump and looked at all the specs on every pump I could find and noticed the Edelbrock pump is the only one to use 3/8" fittings (short of a high dollar race pump) so I ordered it. Checked it out when it arrived and upon close inspection I see that even though it uses 3/8" fittings if you look inside where the fittings screw in the i.d. in the pump body is restricted to 1/4" just like all the other pumps. IMO you gain very little with the 3/8" fittings it's drilled and tapped for. The only advantage I see is you don't have to use a 1/4" pipe to -6 adapter to install -6 fuel fittings. The 1/4" i.d. pump body inlet also explains the GPH rating not being higher than the Carter pumps. It seems to work fine, just thought I was getting something better by spending $50 more. Now I don't think so. The Carter M6270 340SFastback uses seems to be as good from what I see and it's $50 cheaper.
