My stroked 318/390 - M1 intake, .5" spacer.

....ran 425 FWHP with a 800cfm TQ - completely un-modded except for the choke shaft being removed.

I swapped to an Eddie Thunder 800cfm and made 10 Rear Wheel HP more.

I'm sure if I'd used a modded 850cfm TQ it would have out ran the Thunder.

67 RO23 clone with 6.1 SRT Hemi and dual quads. Soon to have Drag Pak induction and Throttle body.
