Like I showed..they are running 5.80's with 440ci... something the Pontiac can't do...

We also have multiple 3500lb street cars (full interior, registered, regularly driven on the street) with turbo LS combos running 7.30s-7.50s at 180-190mph on 275 radials.

I think the widespread use of the LS across so many brands and platforms really helped drive development of aftermarket parts compared to the much narrower focus of the Pontiac engine (one brand, older tech needing much more upgrading). In all-out drag cars down here in Australia we're seeing LS engines be replaced by hybrid designs like the Noonan Hemi-headed LS and the like as people chase ever more horsepower.
