ask absolutely ANY questions you have here, or in the Mustangworks chat room which you can get via this website, or using an IRC client (recommended:
www.mirc.com) and connecting to mcclainenterprises.com and the room is #mustangworks. You can ask questions there and get immediate answers when people are there (later at night, ie after 7pm EST). you can IM me at dinomite1 if you like as well.
The only way to get real power out of that 6cyl is to supercharge it, as was said above.
