I did actual search this, and found pretty much what I was looking for. Normally, going this route increases the under the curve torque and hp, and the the hp comes out to be about even up at peak--correct? My question is, does the difference in power and torque show even more so when you go w/ the bigger cam/head packages that we are seeing on the market now?

of course you wont see the max gains unless each are done together (heads/Cam-headers), or (headers then heads/Cam) is that what you're asking? each benefits from the other

I should have been clearer. What I was asking if the LT outdue the Macs greatly when going w/ a big h/c package.

Do LT's outflow midlengths? Yes. When going with a bigger cam and heads do they benefit from greater exhaust flow? Yes.

How much though?

Not enough to make you switch. Just cut off the ball flanges and weld in 3inch collectors with a custom y-pipe. You can also port the primaries.

I agree. I did the switch and wish I would have stayed with my macs. Not worth it IMO.

Did you feel like you lost power, or had problems w/ your lt's? For the price of Pacesetters right now, I could sell my setup, and buy the Pacesetter's w/ the new TSP Y Pipe, and only be out a few hundred. That might be cheaper and easier than modifying these.

It really depends on how big the cam is. If you go with like the T-rex cam, the LT's will make a much greater differance than if you go with an LS6 cam.

What kind of cam are you looking to get/ what kind of heads?
