Sleestack, now that the cats out of the bag I have a question. Are you making your 4.3 liter into a 6.2 liter or have you replaced the engine? It appears from the pictures that you have posted that you are making your 4.3 into a 6.2 but that seems like a huge increase. Any early hp estimates?

The 5.5 liter engine starts from the same block as the 4.3, so, ditching my 4.3 and increasing the displacement on a 5.5 would not have made any sense. No real estimates on hp and torque, but all aspects of my car should be significantly improved.
