Review on Spectre Performance 42303 Water Neck Upgrade for Chevrolet: Enhanced Functionality with Included Hardware by Michael Finnegan

Works well and looks good. The neck diameter is narrower than my stock water neck, so I need to buy a new radiator hose to get it to fit properly. I have a 1967 Chevy C10 with the 327 V8 option. This fits several GM Small Block applications so may be correct for other applications or vehicles. The fact that my original upper radiator hose didn't work doesn't make much difference, I just tightened the hose clamp, but in the long run it will damage the end if the hose and I buy a new hose with an appropriate neck size. I ordered another version with the wrong neck angle, it also had the same smaller neck diameter as this one, so they may all be similar.
