3.23 to 3.55?

Swapped the 3.23 for 3.55 in the landyacht several years ago. Made a noticeable seat of the pants improvement in take offs. Stock 318 bottom end, 340 6pack cam/heads/intake, 225/70/15s 69 Fury ragtop. I'm also 2.5 hours from Carlisle. If I keep my foot out of it, I can make it there and back and almost there again on one tank. Also have no problem running 70 mph on the interstate. Do it. You'll be glad you did.
