What options are out there besides the original SixPack stuff, the repop stuff and the B engine manifold from Edelbrock?

I thought Offenhouser made one long ago, anyone else?

A lot of offy stuff is still available direct from them.

The Edelbrock is the best.

I should have been clearer, I'm looking for used stuff. Hey I got a family to support. Just wondering what to look for.

It's going to be somewhat expensive, no matter which route you go.
Probably your best bet is a good used Edelbrock aluminum , or original cast iron intake, both very easily available at swap meets and e-bay .
Most expensive route would be the Edelbrock STR 14 with 3 x 2 top plate .
As far as the Offenhauser, the only ones I am familiar with are set up for
either strombergs or webbers ?

This Offy intake looks like it has a Holley carb bolt pattern. shruggy

Then, how about 3 Rochester carburetors?

Carb bolt pattern looks wrong.

OP, both of these Offy intakes are awful performers down
The open plenum 360 designs ruin the low speed throttle response on these intakes as well as all the single four barrel and dual four barrel intakes Offy made down
The old and older two barrel carbs they where design for aren't worth using in todays world twocents work
the three bolt are for the early, pre 1958, Stromberg Carlson and older Holley two barrels, the four bolt patter is for the early low CFM flowing Rochester GM two barrel carbs, the later bigger ones where a liitle bit better but no where as good as the later Holley 2300 type two barrel carbs use on both Mopar 440 and Chevy 427 Corvettes starting in 1967 and the earlier 390 and 406 Fords back in 1961,1962 and 1963 scope thumbs

The offy intake might do ok on a bone stock engine with stock heads and cam. Even if that was true they're not cheap enough to be worth messing with.

Never heard anything particularly good about the eddy STR intake with the 6bbl top plate. They are too expensive to gamble on IMO.

The high rise weiand 6-pack tunnel rams, from what I've read sound like they are a great intake. Not cheap either and fitment or non-stock appearance is an issue for some.

The edelbrock stock type 6-packs seem to do well even into the 550hp range.

I agree with bigmoney.... the cheapest will be an aftermarket Edelbrock aluminum which cost about $410 new...maybe cheaper if you can find a used one.
