86 CJ7, stock, 3.31 with the t5 and 258 combo, 33 inch tires, 4 inch lift kit.
Top end is appromite 75 mph, T-5 trans was just rebuilt and no issues with engine, (new Webber 32/36). Jeep runs like a top with exception of low top end. What are the options, besides replace engines. Want to know if there are options for changing gear ratios to improve performance. Does the front transaxle need to have changes done also for 4 wheel drive options (Dana 300).
