Been 6.02 so far at 3000lbs...with my little 400/512....It just seems like it does not pull as hard down track as my previous 440/512.....Which got me thinking about the bigger strokers they offer...The 526 and then the 543....Seems like my current combo with 20 more Hp would make it...

I just don't know about a 4.5 stroke in a stock block...
