How to build a 13 second 340 Duster

I'm planning a restoration on a 73 Duster 340 4 spd for street use. The 340 will need a rebuild and I'd like to achieve a 13.0 1/4 mile time. It will likely weigh the typical factory 3300 lb or so. The rear tires will have to fit in the factory fenders. I expect to have to replace or re-arc the springs.

I'd really appreciate some input as to the most practical engine build up to get to 13 seconds or just under.The only ideas I have so far would be to up the compression but not so much I can't run pump gas, and add headers. Maybe I should enlarge the intake valves to X head size. What else? I know there's lots of ways to do it.

I'm hoping I'll have a great plan in place with info gathered here.
