Presenting the new Ford Y block 272, 292, 312 valley cover manufactured by Blue Thunder. This piece was designed to be able to fit most Y block engines without removing the cylinder heads. In helping the manufacturer design this valley cover we found that it is able to be installed in most applications without removal of cylinder heads, however 3 out of 10 engines in out shop required slight modification (grinding under intake port locations) in order to fit without removal of cylinder heads. We found if there was excess material left on cylinder heads during the casting process the plate required modification for fitment with removal of cylinder head. Sure you can grind the cast iron burr/flash parting line on the cylinder head down, but the truth is that it’s much easier to just modify the plate. This plate comes with the oil fill hole machined and 5” oil fill tube.

In the back of the plate you’ll find a 1/2” hole with built-in mesh filtration that is designed to pull crank case ventilation from engine without sucking oil, so you can run a PCV valve in place of the provided 90 degree fitting if so desired.

This plate has been shot pinned with stainless steel for a magnificent finish that will not rust and easy to clean (unlike other manufactures that still use iron shot on there aluminum that causes discoloration and rusting).
