I picked up a 4.0 litre Jeep to go along with my 258 bottom end. I also found a I6 Jeep header set-up at the swap meet cheap. I remember someone stating what interference problem to expect putting this exhaust in my American, but I don't recall what they will be. Since my 68 beater is getting an engine transplant I test fit it and I couldn't get a good handle on the cleaence, as the stock stuff is still in the car. What should I expect?....Russ __________________________________ Discover Yahoo! Use Yahoo! to plan a weekend, have fun online and more. Check it out! http://discover.yahoo.com/
