Technical Need more help with Edelbrock 6X2 fittings

Many thanks to the HAMBers who told me last week what size the water inlets are on my 6x2. Now, another question...... Found a fitting on one of my core Y-block water pumps which looks to be similar to what the builder of this gorgeous gold engine used, and that's what I want to use on mine. But I can't find them anywhere, online, parts houses, even hardware stores. Looked at a ton of pics online from several vendors, no dice. Pics show what I've got, and what I'd like for it to look like, so I need 4 of them. Any help? Who owns that gold beauty? I know I've seen it on here, is it Moriarity's? Thanks!

 

Been looking for something similar my self for a crossover on a 331 hemi I want to make modify a dry manifold for .

 

This might work

Swade, that would work if it was 3/8" pipe. Don't want to drill the cast manifolds any larger. Thanks. EDIT. My understanding is that the outside diameter of a 3/8 pipe thread is actually 0.675, so that matches my pic.

 

I see a lot of 5/8" hose x 3/8" NTP fittings if the 5/8" hose is big enough?

 

3/8 barb fitting. Check your local hydraulic hose shop that’s a common fitting

 

Thanks for the replies, folks. Still looking for one with a 1" end, but 5/8 may be my best current option. But now I realize that the 3/8 end is so small that going bigger on the hose end won't make any difference on coolant flow. Duh. I'm not as smart as I look.......

 

FWIW I tapped 3/8 NPT holes in the front of SBC heads and plumbed the coolant through 3/8” hose to a divorced thermostat housing and have never had a cooling issue even in 106* temps in Oklahoma.

 

Cut the treaded portion away then tap it 3/8” NPT then use a close 3/8” nipple.
