Has anyone ran these or heard any thing about them?? I was prtty much convinced on a Pro-Systems (still am actually), but i want to compare as many products as i can.:)

I will be going from a 850 to a 1000 from Prosytems. over on chevelles they have a post about the same change, tuned the 850 for several years, got all it could out of it. PS carb out of the box .1 faster, still needs to get teh bog tuned out of it! So am confident in the PS carbs still, myabe these are better?
