Is anyone using the typhoon intake manifold from P.P. is it good quality or does it sux. My friend wants to install one on his 90. GT but wants to know if he should just spring the extra money for the edelbrock.

Same design as the edel performer. If your friend has time to clean up some of the casting he can save some money by going with the P.P. intake and it will flow just as good as the edel perf. It will move the power band up... so it may or may not match what he has on the car already.
