Interesting, I just wanted to add that Killerbee found during his research that some of the mouthpiece inlets he removed had already been ‘Dremeled’ from the factory.

GM did in fact realize their design flaws and modified the pieces for production vehicles. At what stage of the LLY production this was done is not known. This disparity explains why some LLY’s have more serious overheating problems than others do.

While this ‘Dremel Fix’ does reduce turbulence, it far from eliminates the total problem caused by this bad design.

And while modifying the exhaust to lower EGT’s has positive results to counter the effects of this Thermal Feedback, it is much more costly and it doesn’t correct the real source of the problem.

I’ve got some free time tomorrow, going to the parts house to compare the mouthpiece dimensions from the LLY versus the LBZ, for a possible adaptation without exchanging the complete air intake setup... hey, I’m a tinker-er. Come Sunday, we may be 'Dremel-ing' a bit here also, or at least find out if GM already did it, as this 05's production date was late in the year.
