But, with the better inlet setup and 3.0 cams plus good stem seals it should run nicely!

Been watching this thread with interest Roll Eyes

. After seeing what a rebuild does to a 4 pot without any mods.

Planning on rebuilding a v6 when I get hold of one.

But with lower compression on the 2.6/3.2 and changing the ancilleries to make up for this. Does that mean a 2.5/3.0 could potentialy have more power if the best bits from both engines were fitted?

So its just purely the bolt depth/height which differs then?? As the thread is the same...
