Poncho article: SD VS HO, tribesman chime in:

[71-LS6]

I just skimmed over that article last night, the peak #'s on the HO were surprising and impressive @ 544 torque & 429 Hp. The SD came out pretty much where they thought it would @ 494 & 391. Jensen was definitely playing in his own yard, both engines produced those #'s in pure stock legal condition. That article gave me an unnatural craving for Pontiacs.

I think the interesting thing is that the 429hp/544tq still only put the car at a 12.88 time. They were getting 1.96 to 2.02 times which are pretty good as well. Something isn't quite right. The car should go 3 or 4 tenths faster with that performance dynoed. I know Mark thinks the 3.90 gear replacing the 3.73 will give more performance but is it worth a couple of tenths? The dyno numbers are great but the performance in the car has yet to be had.
