Modifications to Offenhauser 1 1/2 carb spacer Thermoquad to Holley pattern ?

[Brooks James]

CORRECTION !! Spread bore to spread bore Was lucky to find This. Ill have to get the stock phenolic gasket for the base it overhangs. Looks like i will be pricing a grinder/dremel.and making a metal gasket
For the base. Yes,Semea like at lot of effort but its a 60-70s piece and im using as many era
Correct speed parts, as well as pieces that would have come off a Stock mopar.

My questions are:
1) should I hog out the marked area, will it create turbelence, if not will the extra plenum area help?
2) IAm going to leave enough spacer to have a center divider, to take full advantace of the dual plane intake
3) i have read that spacers can help, do nothing at all, or hurt performance
Im guessing that a spacer will help more with a single plane intake, not as much so on a dual plane ?
So I surmise that by not keeping / making a divider, i will change the flow charestistics of the dual plane.
4) my intake is a Chinese Air gap dual plane
Said to have a 1500-6000 sweet spot, stock magnum heads, street/strip cam, and Dougs 1 5/8 headers

That looks like the casting has a lot of porosity in it.

Well, of course I've modified things. But I only modify things when I have to. What you have there does not need to be modified in the least in order to use it.

My thought process on how to use it without modification is to pitch it in the trash can where it belongs.

There are much better options for under 20 bucks that won't look all jerry rigged to hell and back.

Not at all. I just called it like I saw it. I never "slam" you. I tell the truth. You just don't like it.

I don't throw anything away, Ive lived to regret it.

Well you can make that plate work. You'll need the thin Edelbrock plate to seal the bottom and then you have a lot of grinding ahead of you. But no way would I do "all that". Here's what I'd run. It will work fine.
