Tech Notes: 1994 - 95 SC's have a torque modulating system that will attempt to counter the effects of any of your mods. ALL modified 1994-95 machines should get EEC upgrades. A proper EEC upgrade should mean 20 or more RWHP with any cam and it makes for good driveability on "B" kits and Stage-3. Proper stall converter will be more effective than shortening gears on automatic vehicles. All cams will be dependant on blower efficiency. A marginal exhaust, blower, intercooler, or too much OD will lower effective RPM. When rebuilding the 3.8 liter, mill a fresh .005 to .010" from block and at least .005" from heads. Buyers should size push rods/shims to give .025" to .030" preload. Use aftermarket pushrods for Stage-2 and Stage-3. If you want to go over 5700 RPM's you'll need to upsize your exhaust valve.
