I have the Ford 400 stroked 434. I had mind changed to a 3.44. It is a joy to drive. Ive got 434ftlbs of tq at 2000 rpm so i needed to drop the rpm.
Before, 1st gear was absolutly useless. 60mph was way too much rpm.
Now 1st is in a perfect range and 60mph is is just a little over 2000rpm. Perfect range for this engine.
