Okay so I recently bought this sbm intake manifold in hopes of doing a 4 barrel swap on my '87 Dodge D100s 318 sometime. But before I do anything, I'd like to know what this intake manifold might be off of, or if its some kind of aftermarket piece. Its aluminum and looks like its for a thermoquad application. It seems odd that its aluminum because it looks stock/factory but has no other markings besides the part number on the top and the number 4 on the underside. I just don't know enough history on these things so if anyone out there can point me in the right direction of where this intake could have come from it would be much appreciated!

 

Yep.... SBM... LA... Intake.... You guessed it...

 

Guessing it was off a 78 or later Van more than likely... Should swap out without and issues for you.
Dont forget... You will need the 4 barrel Trans Throttle valve linkage and pivot and also the Throttle Cable bracket. Cable should be ok...
If its a 4 speed car... Delete what i said about the trans Valve linkage...

 

Cool, thanks for the info I appreciate it! I'm assuming I would need that bracketry if I used a thermoquad. I'm sort of a fan of Holleys but would any Holley carbs even work on this application? If so any reccomendations? Looking for something decently mild since its stock besides headers.
Last thing, you wouldn't happen too know why there isn't any other markings on it would you? I'm assuming its some sort of aftermarket/replacement since I've been told they didn't make factory intakes aluminum. Thanks again!

 

Lobar makes the transmission linkage you need also.

 

Not 100% sure.... But it looks like a factory one to me... Just a later model with the thermostat housing tuned... I would guess something just before the Magnum intakes?
