Twin Turbo 383 questions

Well with 1 single turbo using a PT8847 there are guys running in the mid 8's with little 347 cu in Ford's.................Damn that is FAST! So one of these as a single would work well no?? Should be able to do the same with a little 360 it seems! I may change gears on the turbo choice. I was starring at the 67 tonight and twins would be a chore to get in there for sure! I think you are right with the GT45 it would probably hit the 700hp range with a 410 CU IN engine, checking it out more it would run out of steam up top.
