Not Ranked
Strokers are great for these reasons: more CID, more leverage at the crank makes more torque, less weight than going to a big block, did I mention TORQUE. Contrary to popular belief, you can spin a stroker to high RPMS, and your valvetrain will still be the limiting factor, if you have a good crank, H-beam rods, lightweight forged pistons and ARP main studs. Long rods are great, but then you need custom pistons. Don't forget the other little details like a small diameter cam so it doesn't get hit. You can easily make 400/400 in a 351 without stroking it, but if you had gone stroker, you would have another 50-60 just because of the cubic inches. I suggest having it done by somebody that has experience in building max-effort stroker windsors. I wouldn't run a dual plane intake on a cobra, they are light enought to not need the low rpm help, run a vic jr. just my $.02
