Inliners International Forums General Discussion Hi Performance Split exhaust and more power!

..."my rear axle has a ratio of 3.08" BINGO!! No doubt, try the user friendly (or numerically higher) 3.55 ratio, with guaranteed results, your motor is stuck in the basement with those 3.08s, even the light 3.08 geared '63 Chevy lls were slugs compared to the same bodied '62 Chevy lls with their factory stock 3.55s. High school buddy's dad was make-ready boss at Friendly Chevrolet in Dallas at that time and had both years of Chevy lls with 194s--the '62 with 3.55s was a shocker, while the '63 and its 3.08 gears was the dog everywhere, it even had worse milage--now if you were running downhill at Bonniville, or needed a bit more traction, a set of 3.08 ring 'n pinions or two, laying in the trunk on the right side, might help--NO where else, they are worthless to a poor six. My own '63 Chevy ll with a split manifold 194 would do 95 mph flat out, with either the stock 3.08s(about 4100 rpm) or with a with a later installed 4.11(5500 rpm). but one way took about a day and a half longer to get there. The 3.55s enabled a nice compromise and could easily top the century barrier as the motor could also spin 5500 rpm with that gear ratio (in high gear). Theres a good chance that car will go faster if strung out in second gear--do the math
