70 Duplex manifold mod

Ewallace · Jan 24, 2013

Have a Div 2 John Deere 70 with 12-1 compression and some head work. Thinking about cutting back the center divider in the manifold to pull from both barrels. This tractor has a stock stroke so it's not big cubic inch. Will this be too much carb? How far to cut back?

I wouldn't recommend doing that unless you want to look for another manifold to put it back the way it was.

I prefer the intake and exhaust manifolds from an LP 70.

Eddy, your gonna need nitrous to beat those G's!!

It is an LP manifold. We also have a G that we run slightly lighter.
