Or on a Ford Racing block for additional cost. There are a lot of "seasoned" Windsor blocks running around in the mid to high 400 HP range and if you don't need to spin 7500 RPM they will work well enough.
I know of many factory blocks in Cobras and other cars that do a fine job of what is asked by reasonable power levels. I still love the guys with 600++++HP in their Cobra and BFG TAs on the wheels!
