Rearend gear ratio
Pontiac 474ci
Max rev 5200-5500
Turbo 400
275/35r18 rear tire
Are 3.73's to low for that motor/tranny/tire combo
Found a few 12 bolts for sale it all have that low gearing.
Was playing around with speed calculator and the Rpm will increase from 3000 to 3400 compared to a 3.31 gears. Any thoughts. Thank you
