I purposly installed a tachometer to monitor shift points on the flattie. Runs out to 4500 quickly in first gear and with the 4:11 and can practically start in second. At 4500 am I pushing the envelope so to speak? Thoughts?
Frankly at 55mph plus the old girl makes me kind of nervous but then again I'm used to driving my 34 street rod with modern independent suspension and disc brakes. Just saying!
Tomorrow I run the flathead out to 50 plus to check rpm's
