Is there a big h.p. advantage to the newer casting tfs a tunnel ram over old design?

The new manifold tunes a bit higher in the RPM range so, different engines will get different results.

I have seen three completely different tunnel rams for the A460 heads side by side by side.

They all seem to have some unique positives to them that would make one more suitable for an specific application which early style are you referring to?

Rolling Eyes which 3? What differences? Which applications? What unique differences? Post up some dyno numbers for all three so we can all see the differences.

I really have never personally dyno tested the earlier "Holmes" style manifold. I understand that it may provide a broader torque curve due to the longer runners.
However...I have done lots of testing with the current Trick Flow tunnel ram, and find it to be a very good design. It seems to be extremely efficient and versatile with various carb and throttle body combinations. It will pull hard from 4900 to over 8200 RPM. It has lots of material for porting and welds nicely for modifications. Yeah..it is heavy...but that can be whittled away.
I am working on a billet runner manifold that I will test against the late model TFS unit, but do not expect much gain.
I am not aware of a third design...other than older castings of the current one. They are the same, but the words "Serious Horsepower" are cast in to the sides and top. New ones just say Trick Flow.

The 3rd design: Back in the '80s Rick and mike Smith did two t.r. styles....most people have seen the 'holmes' long style deal and that's what most of them were. The other early TFS t.r. had very short runners and damn near looked like a blower manifold ,which is another reason there are not many alive today, several were sacrificed to make blower manifolds.
