Stroked & Blown Intake Manifold From what I've seen so far, with both a 78mm and a 90mm throttle body, the FAST intake is marginally ahead of the LS6 intake, and both are well ahead of the LS2 intake, as far as air flow and power output on a stock LS1 or LS2 engine.
Has anyone done any hard data-gathering on intake & throttle body combinations yet on a stroker and/or forced-induction motor?
Trying to decide what to put on my 402 LS2.

they did a test in Hot Rod, and the LS6 produced 8hp and 16lb-ft with the LS6 tb over the LS2, and the LSX produced 7hp and 8lb-ft over the LS6. they made 499hp with a few other things. check their web site for the full article

Yes, I've seen the article in Hot Rod. I'm looking specifically for data on engines with BIG CUBES and FORCED INDUCTION. The results are likely going to be different than with Stock displacement and Normal aspiration.

With a 346 LS1, the LSX is actually WORSE than an LS6 for a street motor (which mine is primarily) and hardly worth the price to only get an extra 8hp above 5000rpms. The LSX is ONLY superior on a pure racer that sees nothing but high rpms, according to the data I've seen thus far.
Now, instead of everyone here just speculating, or talk about stock-sized NA LS1s, who actually wants to address my question with some dyno charts in hand?
Someone, please? I know there are some blown/stroked guys out there...........
