havent been able to find anything out there for the 4.8l. was thinking of going to a 5.7 or 6.0l but i think doing something to the 4.8 would be cooler since not to mant people have done it. building it to turbo on e85. any suggestions would be great.

If there's nothing out there for the 4.8, you'll have to have custom pistons made. At that point, it probably won't be that far off from having the blocked punched out and building a forged 5.7 with off the shelf parts.

Contact 8ALTNG, he's the only one I know of with a forged internal 4.8. He might even still have it too. He made something like 650rwhp with it too with around 18psi. That's pretty much the badest 4.8 I've heard of.

$500.00 pistons and Rods are yours. Add the balanced crank and for $650 you can have it all.

8.5:1 CR and it has been spun to 6600 rpms so far. I have the block as well and the heads too.
