Cruise friendly low 12's with a 340 Dart

I have the adjustable pinion snubber which works well when it hooks.

Gear vendors OD looks interesting but at nearly $3,000, it's out of my budget. For a casual cruiser, you'd never recoupe the expense. The 518 swap makes the most sense and is the cheapest route IMO but I just hate the idea of cutting my floorpan to make it fit.

Other people have mentioned a TBI setup or even swapping carbs for long cruises. I even thought of just disconnecting the secondaries for cruising and running the primaries pretty lean.

A couple of people have also mentioned dropping down to a 4.5 powervalve since I pull 10" of vacuum.

Keep the ideas coming!!
