What size TB should I go with?

As some of you may have read,  I'm installing the Trick Flow top end kit on the 5.0.  I got the street heat intake rated for 0-5500 RPM's as an optimum runnning range.  I'm going 24#'s on the injectors and was just trying to get a feel of what size TB I should go with.  I'm 90% set on a 70mm.  Just wanted some opinions on it.....

I am leaning twoard 65,.... But after seeing that you have hit 13's you might be able to handle a 70 possibly a 75 fine. I would shoot for 70 even though I already voted for 65.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

65mm....plenty big and will support lots of power....plus it will have better throttle response. Don't bother with a 70mm unless you run a blower.

Yep....The "bigger is better" rule does not apply here because contrary to what some think, you can "over-TB" a fuelie engine to hurt low end performance... a 65mm will easily support block splitting power levels.

I was running a 65,and for my modest mods,I had to go back to a 60.Much better.Perhaps after I get the GT40 heads,the 65 will go back on.
