Mine could easily pull a higher gear, it's a '57 LCF stock 283 V8 2 bbl., SM420 trans and 7.10:1 rear end. Even with 100 bales of hay on it it's not struggling, right now I have 8.00x22.5 0n the rear, I'm looking for 10.00x22.5 and it should help a little.
1957 Chevrolet 5700 LCF 283 SM420 2 speed rear, 1955 IH 300U T/A, 1978 Corvette 350 auto, 1978 Yamaha DT175, 1999 Harley Davidson Softail Fat Boy
