Truck intake ? I am starting a ls1 rebuild to put into a classic truck . I am wanting to build lots of low end torque for a heavy truck and i just like lots of lowend power, shouild i consider getting a truck intake of mabee tbss intake. I have just heard / read that the tall runners make more lower end power ?

Longer runners help improve torque lower in the rpm.
So, yes.
Also, keep exhaust diameters to a minimum to keep the powerband shifted in the lower rpm range. You WILL lose peak power numbers, but it WILL pull harder at lower rpm. If you go with headers, ones with a small primary diameter and longer length will help you see some more low end.
Just make sure you match ALL the parts for your goal. Keep this in mind when choosing a cam and heads, also.

Yes the Truck intake would be the way to go, They do produce very good numbers on the low and mid range and can show better number in those RPM Range as compared to the LS6 or other Higher HP intakes.
One key to good low end is as producting High HP is air velocity speed at the correct RPM Range. Larger intake runner and port maybe not be the correct call. Keep the intake runner, valve, cam and exhaust size to the correct size for the RPM Band and you will produce tons of TQ !

The truck intake is every bit as good as the LS6 intake and is superior to the LS1 intake. People have gone thru the hassle of changing out the truck intake for the LS6 and gained nothing at the track. The TBSS intake has lately been a much talked about swap for us 6.0L truck guys, because it is essentially the same as an L92 intake, just that it mates up to cathedral port heads. I've heard theoretical 20rwhp gains tossed around but this was in reference to a truck with ported heads. I really don't think anyone knows what the TBSS intake will gain on just a stock motor. You also gotta consider the fact that the TBSS intake will allow for a 90mm TB over the 78mm of the truck intake.
