Its more situational. Some have found that when running a lot of boost that high-overlap cams will allow boost to blow right out the exhaust.
Other have made good HP, but have had durability issues with some manfuacturers of camshafts (the CompCams Super 60 unit in particular) The rollers do tend to last longer and concensus is that the 88 TBI camshaft is the best of the stock roller camshafts for both lift and degree's of opening. The TAFT cams that FWDPerformance sells have shown some power improvements, but they are reground cams with a smaller base circle that does not work with the PT Lifters (if you're using them) So that's something to take into consideration. The MP cams will make some power depending on whether you degree them properly and match them to their use properly. I have a friend with a stock early T1 with a Forward Motion 475 cam and he likes it pretty well. I'm guessing that when we add the newer intake to it, he'll like it even more. I'd have to ask Forward Motion whether they would recommend using that cam on a 2.5 SOHC motor as that's his planned replacement for the ol 2.2 in his car. Like I said, it depends on what your goal with the car is. Drag racing? Road Racing? Autocrossing? Street Driving? What kind of modifications do you have now? What are planned? All of this can change the cam needed. Best Regards, -------------- Original message ---------------------- From: "William A.
