The Trick Flow unit held the benchmarks.
The Edlebrock was close to the TFS and was about $300 cheaper. I would imagine they are all about the same price now......
The Ford GT40 was also a hot performer, probably right up there with the TFS part , but it was also the ost expensive....
As I recall, if you couple the TFS intake to the TFS 5.0 heads, you will bolt on well over 100HP.
