How much does it cost?
Hey Jack -
Here's an alternate suggestion that I'd love to do with my '69 Dart if I had the funds: how about a new-generation Hemi with an Indy Cylinder Head 'Mod Man' intake and black-wrinkle '60s-style valve covers?
That would give you the 'cool factor' of the dual-sparkplug look with semi-correct period styling, multiple carb/fuel injection or 8-71 supercharger setup, and potentially better mileage at a lower cost.
Take a look at pgs. 66-69 of the January 2010 issue of Mopar Enthusiast magazine. They tested various 'Mod Man' manifold tops on a modified 6.1 Hemi and their dyno test horsepower ranged from 613HP/539 torque (single 850cfm carb) to 670HP/569 torque (dual 1300cfm throttle bodies). They didn't test the 8-71 blower.
I like it, just don't have the funds to do it!
