only so much your going to get out of a 6 everyone knows that. whats more important to you. keeping the 6 or scootin a little faster down the road
You might be shocked at what you can do with an inline 6. I have an Uncle that had a '49 Chevy Business Coupe back in the late '50s with a hopped up 235 (virtually identical to what's in my truck) that would shut down the Feulie 283s and dual car 392 Hemis at the strip, plus it was used as a daily driver on the street.
As mentioned, I have a virtually identical setup, dual carbs, Fentons, upgrade igition, .030 milled off the head, I run highway speeds with ease.
The one alteration I will definetly suggest, and other will agree with me, is to add an overdrive transmission. The SM318 or later SM326 were both available with the Borg Warner overdrive, and are a direct bolt in. That would be the best choice if you want to keep the column shift. If you want a floor shift, or have the 4 speed, the T5 is a very popular choice. Both have perfect gearing for the 325, ad work very well with the standard 3.90 rear gear used in the 1/2 tons. A taller tire will help, too.
