LTx intake!!!
For starters, 1000+ rwhp has been made using a stock casting.
Secondly, a back-to-back test was performed between a heavily modified LT4 intake versus single plane. The LT4 made more torque below 5200, they were dead even 5200-6200, then the single plane made more above 6200 (but only about 15 hp at peak). This was with a large solid-roller that liked being over 6000. On most street set-ups with hydraulic cams, you'll spend most of your time below 6200 rpm.

Yes like mike said, I've seen it over and over again! How high are you spinning it? Anything 6500 and under you don't need a single plane. And if you runnin a stock computer you can't go over 7k anyways! So it's all bout the rpm! But if it's worth anything I went with a heavily porter lt4, looking for sum big power with the new build!
