(quoted from post at 16:55:30 11/15/11) Whats the difference in the head? Is the cam different to?

There are several different heads used on the 400 series engines. They vary both in air passages and cooling passages and deflectors.

Camshafts are the same between turboed and naturally aspirated but there are different cams used as engine development progressed. Lobe size and grind contours changed over time. Lifter design also changed as well as lifter bore. Truck engines switched to using roller lifters.

There are probably more differences between early and late engines than there are between T and NA engines.

None turbo has the high swirl head while the turbo has the low swirl one.
