help with 88 pulling motor

The guys that posted before me gave good information and here's some more. The Deere 7700 gas combine used the 404 block I believe so the 1 7/8 or 2 1/8 carb will be too much if you're not spinning it. Plus unless you have a custom intake manifold built, it is pointless to hook one of these up to a garden-hose size stock S88 manifold. The GK195U carb, on the other hand, is a 1 5/8 throttle plate built for a 320 cube motor at 2200 RPM. I have one of these if you are interested. Again, manifold work will be required to get this to run right.

Also---you say you are using stock 88 rods and am assuming M&W 3 7/8 Turbo Domes, how are you making up for adding 7/16 of stroke? The M&W pistons are designed with a pin height for 4 inch stroke and 6 3/4 inch rod.

Good luck,
A.P.
