Hey this is his "buddy" ok I dynod my truck on a chassis dyno I never dynod it on a flywheel dyno. You and 20 percent of your horse at and torque at the axle then add it to the flywheel. Second of all 350 turbos do line up to BBCs I've built 3 and put them behind of that. So don't give me that line of crap. Yes a turbo 400 is BETTER for big blocks but all I had was a 350 laying around and as for running a 12.56 is on the chassis dyno were I could get traction. As for on the strip 1/4 mile I run at consistent at 13.34. So if your going to talk bad about my truck I suggest doing a lil more resurch on BBCs.
