I Have 450 With A Pipe And Jetted. Would It Help It To Run Race Gas Or Would I Be Able To Tell A Difference?

you dont need it, you cant tell a difference... well maybe in your wallet. to tell you the truth, you shouldnt run gas that has a higher octane rating than you need. i had the formula to tell if you needed race gas but with just a pipe you dont.

the only time when you should start running race fuel is when you bump the compression up to around the 13.1 ratio don't waste your money for no power gain.

You dont need high octane. That doesnt mean race gas wont make a difference. U4 by VP is a low octane fuel that will make about 6% more hp than pump gas.
