I have some parts sitting on the shelf, and am waiting for the rest to be sent over from the US.
These heads have everything the Ford Yates and SB2.2 head have, but I wouldn't be surprised if the Toyota head is better again.
There are plenty of raw castings out there for a full effort engine, but I doubt there is really many Mopar folks preparred to build one. Anyone serious enough usually build a P5 engine, or are still running a W8 engine with a cast 4 barrell.
The adapters should be cheaper for what is in them, even at a 200% profit I don't think there is $950 in them. For a 1 off, sure.
Great post and great info Leon!
