The T-II is an EXCELLENT intake.
However, they REQUIRE at least a 1" spacer to get full potential out of them.
Square flange only is another downside mentioned.
The T-II with a well made spacer/850DP/HP950 on it will rival the Victor/Dominator out past 650hp, back to backed them on many occasions.
It still doesn't really start to shine over any dual plane intake till past 4400rpms or so, and will give up some "grunt" down low, etc. If you want bragging rights on a dyno run, by all means get the T-II intake, put at least a 1" spacer on it, or an adapter if you are using a spread bore carburetor and good to go.
For most of these engines the RPM will be fine, if you have the clearance for it, and don't mind some "cobbling" on occasion to install one.
If you are into "stock appearing", or just like to use as many stock parts as possible, for most set-ups we see talked about in the street section, it's difficult to outrun the stock parts anyplace, especially if they have been "massaged" a bit by someone who knows their way around these things.....Cliff
