12.12! WOW,that's some PRETTY SERIOUS testing & tuning!
Now if I'm understanding your post Jody, Paul needs to pick up WELL over a second with the recently dynoed SD motor (to keep up with MarK)
Does his newly found additional HP (25) & TQ (34) equal a full second in the "low" teens?
Also curious about 2 other things:
What brand of crossflow did Mark just install & is it a 2 1/2" unit?
Personally,I've never seen (or heard) af any SD's with factory installed 3.90's.
I thought that 3:42's were the steepest that was offered (and 3:08's were MANDATORY with A/C) or is that NOT a criteria?
(I'll have to dig out my old HPP's & re-read the tech specs)
Keep that GREAT 455 Round Port info COMING!
