Cam's 98 cobra

The 96-98 intake cams when installed in 03/04 Cobras offer little power gain. I've seen people do the swap and lose power down low and get no increase at peak. This is not uncommon. IMO, when using the cobra intake cams in a 03/04 they should be installed 4-5 degrees advanced which puts the LC at 114-115. This places the intake close a couple degrees later than that of the stock cams but opens the valve much earlier to so that cylinder filling begins sooner. Also, the split in the int/exh durations becomes quite great and in the wrong direction for a PD blown car. Boosted cars need more, not less exhaust duration when compared to the intake side. A supercharged car should have equal durations or more on the exhaust side. IMO, the only benefit of going with the Cobra intake cams is their larger bolt. The exhaust cam at a minimum should be changed to one with a 12mm bolt as that is the one that most commonly breaks
