Re: help with optimal gear ratio for best 1/4 et 3.42 or 4.1
When I was looking in to a 200 4R for the 81 Malibu I thought about 4.30 gears. 4.30s was a option in Camaro`s/Firebird`s and I have see them on Ebay. With 4.30 and a .67 overdrive that brings the gear ratio to 2.88 highway friendly gears. 4.30s will deffently get any car moving. Doug
