I'm doing almost the same thing. I've talked with GTM about their 4.2L upgrade. I was told to avoid the 4.5L due to what they have to do to the engine and could be a pain...meaning it's really for tracking and not DD. I'm going to buy the whole engine including the block. That way I have a back up engine and they run about 16k for the whole engine but it's rated for up to 800hp. Oh choices.....when your done pulling your hair deciding which way to go let us know and good luck with your build!!
