Need to move my regulator to the front of the carb to allow better access to the valve cover. Anyone know off hand what the center to center bolt spacing is for the two front studs? Single carb, traditional mounting(not sideways like some tunnel rams allow...)

The standard "square-bore" for 4150's et-all is 5 3/16" x 5 5/8", according to my Holley manual.

Great, That narrows it down...Anyone know which is across the front?

 

[Oldsquirt]

5 3/16" is side-to-side measurement.

Thanks Oldsquirt!

Yes, the narrower dimention is across the ends, wider is down the side.

Thanks Oldsquirt!

You too Smokin!
