i know 6port irons can be bridged, but can i get the same power as a 4port? everytime i hear some1 doing a 6port bridge theyre keeping the stock manifolds. im going with a jtech manifold with a 600 holley. does anybody have any numbers on full bridge ports on 4 n 6 irons? the reason im concerned with this is that i have 3 sets of 6port irons that i can use but i was told to get 4port irons being that they will yeild more power but they were using stock manifolds. it would be cheaper to go with 6port irons (being i already have them) if they yeild the same power advantages or similar.

i know bridgeported has done these 6port bridges. but does anybody have any experience with them on a carb?

thanx

 

A bit over the topbut this was a 6 port housing

compared to four port

 

wow, did you do that to all 3 plates? did you put it together

 

Now those ports look nice, but I would think a port that big wouldn't work as well as a smaller port (or two).
