I seem to recall that all the 4 valve 4.6 engines used forged cranks.
BUT, see the cam drive system and the bore/stroke as major problems as a
full boogie race motor. As naturally aspirated, getting compression up to
where it really needs to be will be really hard. When I talk to oem guys,
most just don't get it relative to real race stuff. Especially management.
For those that are interested, I have found a spreadsheet that shows all
ford engine weights, and appears to be reasonably complete and somewhat
accurate.
No Bill, no cast steel.
