Thanks for the replys.

Jon: No this is not a 235. It's a 161 inch f-head Willys motor. I've seen pics of this modification and am going to give it a try. The three times I've seen pics of it one used the Yh carbs and two used SU's. I've got three YH's so I thought I'd start there.
If It doesn't work I can always change it to fuel injection, perhaps motorcycle injector throttle bodies, and mega-squirt.
I'll know more about how to proceed as I get a little further into this. The machine work starts next week to open up the side of the manifold. (integral to the head).

Thanks again:
