Let me know how that works out for you.
Of the options you named, are any converted to run on modern liquids?
When I built my Y-Block I knew a 351W engine would be far cheaper to build but I bit the bullet and did the overhaul anyway. I love the sound of a Y but it is only 300 cubes and not expected to perform miracles in a Galaxie. Looking back, I doubt I would do it again because the engine is all cast iron, the center exhaust ports are still next to each other and the lifters will always be solid. I did a ton of oil modifications, match-weighed piston/rod assemblies, balanced the crankshaft, retimed the camshaft, added a true roller timing set, and much more. In retrospect, I should have used the 351W and AOD. - Dave
