form what i've read the slant six bbd is only around 300 cfm and i'm wondering how i could make it bigger since i have some parts around here from numerous bbd's and not likely all off slants

Look for a BBD on about a 1986 Dodge truck with a 360 engine. YES, I said 360 engine, NOT 318 engine. The 360 BBD carbs have a larger venturi and will flow more.

Gosh I can't believe I leaked out this Mopar secret. Now I'm gonna be in trouble with the Mopar gods.

The 350 cfm 'Large BBD' like off of dump truck 413's, and big blocks won't fit the super six flange, and they don't fit the Mr. Gasket 1937 either..... Any 318/super six BBD is going to be a 280 cfm version.

-D.Idiot

"Got plate?"

This 360 BBD from a pickup truck is the small flange the same as 318 and Slant 6.

Oh my, Now the Mopar gods are really going to be mad at me now.

ok thanks i know of were there is a 360 2brl unfortanatly it is seized but it's not the same as my bbd but could i tear it apart and use parts from it to create a better carb or do i need to live with the bbd till i can get out to a wrecking yard

i'm just wondering what a larger set of jets and other stuff like that would do for it

the only way to increase the cfm is to increase the size of the venturi. changing the jets only increases the fuel delivery going too large makes you run too rich. As far as the 360 isue I do not think it will work as the 360 2bbl is the same as a 318 2bbl or at least it was on my b-body

Reducing the venturi will kill CFM? or will increase air speed?

I was thinking that maybe throat can get you more CFM, and venturi is for regulate the incoming air speed....

The biggest BBD is from a 383, but it won't bolt onto the supersix manifold. A custom adapter would be required. The biggest carb that will bolt onto the supersix without an adapter is a Rochester 2g from a 327 Chev.

Anybody need a big 383 BBD or a Holley 2-bbl from a 400? I happen to have a glut of them at the moment. All run well (on their big-block homes, at least).
