I agree. I know the LQ9 and LQ4 (both 6.0s) are truck/van motors and can be bored out .30 "safely", the only difference between the 2 are pistons that give them different compression ratios, same heads 317 casting #s I believe with 72cc chambers ... You are spot on with the truck intakes making low end power and I also agree with the cam, I believe lutani(sp?) or comp cams make a "trucker" cam that is made for low end power, the cam I have comes in at 2800 or so up to about 6500 if I remember right. The stock cam pulled WAY harder down low when you stomped it to burn those tires. 1.) If you had the $ go with a Alum LSX Warhawk block, bore it big with a good medium stroke ( for longevity, piston wont wobble at the bottom of the cylinder) and high compression pistons 2.) Build a cheaper Alum 6.0 block bored/ medium stroke with 9.5-10:1 compression and put a good small turbo on it if RPMs were staying low The LS platform is so available, cheap, reliable, and able to make power I believe it is the best contender for a V8 style automotive engine (in my opinion) ekimneirbo: You must be an LS guy? Where abouts in Deep South? I like HP tunners. I got it right before I got out of college and started an internship, then flying lessons, and then picked up two jobs and now started a small business while working one job. Sooo I havn't had much time to "learn" everything but it is an in depth program that I don't fully understand but I can get by with it.
