6 sec street Duster combo?

To get 525fwhp@3300 to run 6.8's in 1/8th from your 340 those Eddies if stock won't do it@around 247cfm max flow, they are only around 30cfm better than stock iron heads. You'll need around 300cfm in ported form and either a solid roller or a good solid ft cam and at least 11:1CR + a tight 4500>5000 flash verter, with a 29" tyre and 4.56's you'll be turning around 6900rpm@the stripe with slip.
