Anyone mount a holley on a stock 4 barrel intake? Got a trans dapt adapter but the ports dont line up well and tech support said run it,

its a ‘68 383 newport

wondering if anyone has made a better spacer or dealt with this ,

i should have pictures attached

I can't say I've seen worse but some of the adapters for the early Chevy 4v carb manifolds are about the same and they seem to work.

What do they cal this small pattern style intake?

Internet is your friend.

Check the 4150 adapter Flange Spec.....

At the risk of fixing a problem that doesn't exist, given the price of aftermarket manifolds (and not forgetting the used market), you might think about a swap and loose a few pounds in the process.

You can always give it a cote of paint like the rest of the motor too keep it stock appearing.
