I would say yes they have gone up. I think I have $15-1600 in the porting in my Indy heads and intake from four years ago.
Maybe as more guys run the Trick Flows their advantage over ported Edelbrocks will show up on the time slip. It would be interesting to see what a good ported could do with a set to see what the potential really is.
We had this discussion over on Abodiesony. You can’t buy a head that flows 300cfm@.700 lift and run a .501 purple shaft hydraulic cam and see miracles.
