4v heads on 4.7L??????
Please forgive me if this is the most rediculous question asked in awhile. I am assuming it has been thought of and doesn't work. It never hurts to ask. I have never had the oportunity to really look at an S-4 engine.
I know that the blocks were the same throughout the years although bored out as the years progressed. Is it possible to upgrade a 4.7L to the 4v heads? Are the intake ports in the same location/ If so are the bolt patterns the same? I know the exhaust pattern is different.
I am not inquiring about the engine management, only if its possible to swap heads and exhaust.
Thanks

then, after a 1.5mm bore at the edge, a normal 5 liter ends up at near 6mm for the 6.5 liter stroker. Plus, if you notice, the headgasket is about 1mm wider than the bore. doesnt seal against much meat does it?
