I bought mine, not the best of quality but it is worth the $200 less than the edelbrock ( paid 320 shipped). The Professional products intake is Identical to the edelbrock so it should make close to the same power. If you want to do a good job I would invest in some carbide bits to clean up the ports a little and do a little portmatching to your heads.

A problem I encountered. Some injector holes actually are above the port ( the middle port in the pic) which seems like if ur using a stock gasket, the injector wont fit.. I have seen this on another typhoon intake though so im gonna deal with it. Luckily i have a big port I have to match it to so I should be ok
