RE: stroker plates
Once you stroke an engine past a certain point you must have stroker plates to lengthen the cylinder bore or your piston geometry (position of wrist pin hole to ring lands and skirt length) doesn't work or work well anyway. The extra travel of a stroker piston would either drive itself into the head or the skirt would hit the flywheel or you'd wind up with a piston so short it wouldn't last long.
I think they're usually 0.200" thick and I'll bet that engine has an S&S carb because those stroker plates raise the cylinders and open up the "V" , requiring a special intake manifold.
You'll have to find out what 'wheels are in there. Might be a nice S&S setup.
Another thing, are you sure it's still a 74" (1200)? If it's stroked it's not and the cases probably have been bored to accept cylinders with a 3 5/8" bore (big bores). Sometimes oversize pistons past .020 or .030 can be tough to get for the big bore strokers. Meaning you'd have to buy new pistons AND new cylinders if you need a ring job.
That's what I've figured out.

RE: stroker plates
Thanks Iplugw, dont know what kind of carb but I fugured on opening it up anyway if I got the motor. No I'm not sure of the exact displacement and neither is the seller, but it started out as a 74" not an 80".
Would it be right to figure that these plates were part of a package to stroke the 1200? It wouln't do any good to just have the plates right?
