I think I'm going with the Wiseco Pro Tru Street Pistons and the Truck Norris stage two turbo cam kit.My biggest regret with building my lq4 was not putting a stroker crank in it. For forced induction cam isnt as important as ring gap afaik, you dont want NA ring gap for forced induction. I like the results of the truck norris cam power curves personally though. If you have a big motor budget, you can make a LS very powerful in naturally aspirated form which can be especially nice in a land ceuiser where its usually preferred to veer on the path of mechanical simplicity.
Why a stroker crank?
I ask because I'm a YouTube mechanic. I haven't really heard/seen anything about doing anything to the bottom end.
