Try a 24 Trophy. A 25 is way to large for your rig unless you have the engine too high. Lower the engine till you have only a slight amount of wheel torque. *Use the calculators above to find the best combination with about 6000 rpms. Anything more than 6K and you will be slipping when running on the top. Just use the hub exhaust ring and PVS hole variations to ge the hole shot you desire. A Jaguar is an excellent rig witha 200 EFi on it. Just a really sweet rig for most people. Though it is not a speed demon. Lower your engine and try a 24 Trophy if you like. Find that sweet spot just below 70 and enjoy your rig!BCB
