I remember talking about this a while ago. I think most the newer trucks like 01+ or something had forged cranks. Not sure about the exact date range. So that's no help haha.

Yep, it's the size of the combustion chamber in the head. Stock is 42cc as everyone else mentioned. Trick flow has a 38cc head available to tighten up the compression a bit. I'll be doing the 38cc heads and some dished pistons for a 9.2 or 9.3 CR.

Most modified heads a 42cc, it's kinda hard to add more material later on

I went with the trick flow 195 Race heads with SS valves, bee hive springs, titanium retainers, and 38cc combustion chamber.

The forged crank was hit or miss. If you see WF imprinted on the crank its forged.

You can also get different size head gaskets. They range from .020 up to .120 in thickness. So you always have room to add or subtract a few decimal points off the CR

Don't see any reason for porting heads if you are going N/A and not looking for huge numbers.

I would go with a very slight dished piston -10 or -7 Compression would be great for a NA enginge with a good set of cams.
What do you consider "great compression?"

Thanks for the numbers. I'm pretty sure I'm going NA for now.

Btw is the Navi a 4 or 6 bolt main?

I definitely must have misread something...
And what do you mean by dowels?

Ok. That wouldn't be too bad.
