Given all that and the paint - you sure the block is aluminum?
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!
I was under the impression the L33 motors were gen 3 24x aluminum blocks with gen 4 rods and flat top pistons from the factory, which is why they cost so much. If you paid for a forged piston I see the problem but if it's just a concern of compression ratio I wouldn't worry about it. I think the l33's were like 9.9 vs the normal dished piston 5.3's being 9.5. As long as the ring gaps were opened up it shouldn't have a problem making tons of power. I would almost prefer the flat tops to make it a little nicer to drive out of boost.
Thanks, it needs some love but it is shiny haha. I have to undo some minor hack jobs, like screws where there should be plastic fasteners, some iffy wiring, someone painted the valve cover yellow, etc. The paint job doesn't go into the engine bay or trunk, missing a drivers door panel. But it does have Konis, springs, VX cam, braces,etc, and its very rust free (that is a relative term in the NE) for this area, and it sounds very good. Officially arriving on Friday, so I will show it off then.
