BBK SSI intake manifold
would this work with the stock heads? and a ported stock throttlebody? thinking of adding one of these to my setup. Lg pros,x1 @112lsa, ported TB, plugs, wires, thermostat and underdrive pulley...let me know! wondering if it would bolt up to the stock engine.

Not sure...it would depend on who is doing the work and if they know what they are doing. You can most likley find one already done in the parts forum for a reasonable price.

I have a polished Lingenfelter intake to go with the rest.. but I'd say that unless you want polished metal I would get something else before either the BBK or Weiand.
They will run out of potential (with more effort) compared to the cost of a used FAST intake. And if you're staying mostly stock then just enjoy not fussing with the LS6 unit.

Actually, on my last car I picked up lots of low end torque with the Lingenfelter compared to my LS6.
It's been a few years, and I only saved the final dyno sheet so I forgot what the gains were, but the Lingenfelter has smaller ports, so the high velocity really helped fill the cylinders. There were no negative side effects (for me) with that intake. That's why I bought it back from the current owner of that car, and it's now a part of my LS6 engine. Nice part.
It's been said that you lose about 10-15hp to heak soak on a 500hp engine. I'm happy with mine...

This is why L98s have 350 ft lbs and only 250 HP.

The Lingenfelter/Weiand was patterned after the LS6... so the runners are the same length although contoured thinner which leaves tons of room for porting.
Looking at the intake trumpets at the base of each runner they have a very neat design that I'm sure helps the air velocity as it makes the curve into the runner. Lingenfelter was a genius and I'm glad to have his intake design on my Zo6.
Also, my past car didn't make lower top end... it made more in addition to adding torque down low...
With a medium cam-only on stock (241) LS1 heads making 421 rwhp with "that crappy waste of money intake".
Peace.

Porting the stock manifold wont do much unless you are match porting the intake runners to aftermarket or ported heads. Since you have stock heads I'd leave the manifold alone.

This is the last time I'll post in this thread... I'm not trying to argue, just trying to clear a few misconceptions about this aluminum intake in particular.

. I personally wasn't arguing the design of the intake runners, merely stating a fact about intake runner length as it pertains to power curves. If your intake was designed exactly the same way identically, but made of plastic instead of metal then it would produce more horsepower from cooler temps, which you seem to agree with. Just because it makes more power than a stock GM intake does not mean that it is a perfect design. We both agree that if "power" is the desire of the person buying the intake, then metal is not the answer.
