Frank & Company: Please pay attention to my entire post, AND to the original question concerning gearing. (1) I don't argue that the 4-cylinder in a TRUCK would have 4.10 gearing. (2) But he doesn't want to put the engine in a truck; he wants to put the engine in a CAR. FOR GAS MILEAGE!!!! We aren't talking TRUCK gearing; he wants to know what PASSENGER CAR gearing to use. We're not talking about load hauling a ton of wood or whatever in a pickup TRUCK, we're talking about a passenger car rated at about max 700 pound payload (see owner's manual for details). What I am saying is that when AMC used a similar sized engine in a Spirit, these were the rear end ratios they used. Historically, trucks use deeper rear end gearing than the same engine in a passenger car. You know this, I know this. The guy raising the issue wants to put this engine in a passenger car. He isn't going to haul firewood, or plow his driveway, or go off road with it. He is going to drive the car on the highway! As I recall, the 1982 Spirit with the IRON PUKE and the 5-speed was rated at 37 mpg, highway. With a 3.08 gear. And a .85 5th gear (overdrive). THIS IS WHAT IS WANTED. Mileage! NOT pulling Jeeps out of ditches! Tom Bunsey ============================================================= Posted by wixList Archiver -- http://www.amxfiles.com/wixlist
