Nelson racing engines did this with a 4.8. I didn't believe it at first, but they made some red oculus numbers with the stock rotating assembly. You should check them out. Lots of wild builds including a 4 figure 4.3 v6 build!
I think you might have missed what I am after.....I don't want to end up with a ton of $$ in the motor itself.....From 2002-06 Cheby offered the LQ4. Made 300 or so horsepower & 360 or so pounds of torque. More importantly was the somewhat boost friendly 9.4:1 compression ratio. Sure it lacks forged pistons...however if you tune the afr a bit on the rich side it will help keep, along with Meth injection, the combustion temperatures safe enough to avoid troubles.....or so I was told be several folks that I have been talking to....
Have spoken with more than one fellow at the Turbo forums about this. They all have told me that a cam shaft swap is not necessary for what I would like to do. They said any set of LS heads will work for my goals. Only suggested motor mod was a different set of valve springs....and that was more of a maintenance thing.
Patiently waiting for "The Haters", as Joe calls them to show up and tell me that these guys are full of it. Find that hard to believe, seeing as how not one comment has been made that the info they are giving me is not true.
