Do the 426. The motor is out of the car, just do it once. I did drop ins and , regretted it and then did a 426. I’m at 7 psi on a p1, making 762 at the wheels.Hey, so I’ve been thinking of either installing the drop-in pistons and rods or going with the 426 stroker kit. I am currently running a D-1X on 7lbs of boost on my 2015 392 for about almost 3 years now and I’m loving it. Only problem is I’m restricted with the stock internals and am really looking forward to raising up the boost to say about 13-15 lbs. I know that drop-in pistons and rods could get me at around 11-12 lbs, but I’m not sure how much psi I could maximize on a 426. Keep in mind my car is a 6-speed and I know that the transmission could live for more power. If anyone has the same setup or somewhat similar please let me know the numbers. Any info would be helpful and thanks advance !
Need to upgrade to a d1x myself
