Damn, Im dying to see this thign comtogether. I dont mean to be rude or anything, but Id be surprized to see 400rwhp, but let me be the first one to say I hope you do!! That would be really awesome. Turn some 117-118mph traps... Damn! Just from what I've seen the SOHC 1st gen 4.6 doesnt make that kinda power w/ a blower, but I really dont know that much about it. So good luck, and I'm looking foward to seeing the results!
