Okay maybe it's not stupid. But I know imma get bashed for it but I'd really like to know so... here goes. I know I've mentioned this in a few other posts but I've always liked the look of and the supposed ease of power of the 6.4 powerstroke. So right now I'm in a delima. If I sell my truck I could be 100% out of debt and since I'll be getting married early next year, that would be great. Now of course I would want another truck. Love my duramax but Id wanna try something new. I understand the issues of the 6.4. But at the same time I understand a few people have pushed a stock bottom end into the 4 digits. But I do not want to downgrade performance wise. So I guess now to the question lol. Plans for my truck are nothing more than an s475 kit if I keep it. Makes for a fast truck. It's quick already. Would a 6.4 with the same mods and a good tune be as quick or faster than mine would be (i.e. S475, built trans, and injectors maybe 60% overs)?
