thanks for all the help, i found a local guy whos a dealer for them and he said he'll give me one for wholesale if i put a sticker of his shop on my back window so im all for that. i talked to him today and told him about my uncles block, he said he can get 6.0 short blocks for about 400 brand new and i can bolt all my 5.3 stuff on it and keep my block as a spare. So cam'd 6.0 w/ Radix here i come. He also told me the 5.3 heads will give more compression for the 6.0 than the regular 6.0, he said the radix is fine for 6.0 and that he hasn't seen any problems with it.

Thanks for all the help guys. I'll post a thread when im all done
