I recently installed a new Champion aluminum radiator in my stock 1951 ford ( 8ba . The unit is a direct replacement for this flat-head, it comes with a cap with a 0.9 stamp on it. The manufacture says it is an 11lb cap. With original radiator I always used a 4lb cap. Does this 11lb cap sound correct for my application?

I'll give you some points to consider; I'm sure the new aluminum radiator is capable of handling an 11# cap, but do you want that much pressure on your water pumps, heater core, hoses, etc? The cars of that era were designed for lower pressures and I would be more comfortable with a 4# or 7# cap on my car of the early '50s. I hope you will come back with your experience with the new radiator after it has seen a few scenarios of the summer heat.

That system calls for a (4) pound cap which raises the boiling point to about 224 degrees, which is plenty. Regards, Steve Lee
