THANK YOU Allen!!!! I didn't understand you on the phone correctly. I searched in old threads until 12:30 last night and kept reading,"put 6.0 heads on 5.3L for more boost" and "putting 5.3L heads on 6.0L is not a good idea".
I didn't even think about what role the pistons have in the CR! I guess that is why I am paying you to do my truck!

From what I read last night, the procharger just seems to make the power too high up in the band for me. Everyone is saying that you must use a high stall like 3800 or something. I don't want that kind of power. Unless of course Allen can work some magic and lower the range some??

So unless that can happen, I guess I'll go with the radix unless Allen can persuade me to go procharger. I like the radix install a little better also.
