I flowed a 302 Clevor intake manifold CNC ported by Wilson, and there was 80cfm difference in the end runners to the middle ones. Just porting the plenum on the TW is not going to net any horsepower improvement from my experience with those intakes. The real work is inside the runners where the ledge leads into the ports. The TFS TW flows more air as cast than most FE's can use unless it is an all out big cubic inch high compression build. JMO and experience since I still have two TWs myself. Joe-JDC

$1100 upcharge for porting. Hmm.
While we're on the topic of balancing intake runners, I threw up a video to my YouTube channel the other day about what the horsepower difference is worth between port matched intakes and fully ported intakes.
A lot of the intakes that we use out of the box have horrible flow differences from runner to runner. Joe has pointed this out to me many times: sometimes the difference can be 60-80 cfm between ports. "Port matching", that everyone is hung up on doing, won't fix it and can sometimes make it worse.

Thanks for the feed back Joe and Brent

The Wilson W-302 CNC'd for the local racer cost him a supposedly $2500. When I received it for flow testing, the guy was disappointed in the performance and was trying to find out what was wrong. Sometimes a name does not equate with a better product. Joe-JDC
