I am not sure why so many are fascinated with a 416. For NA sure yea I get it...for FI especially a small PD supercharger...No. 388 is what I would be looking at for a PD setup. You don't need anymore torque around 2-3k rpm that the 416 will add on top of what the little 1.7 dishes out and it's not going to make much if any more power then a 377. Now if you were talking about doing a F1x setup in a manual car, then yea I could see some logic behind adding some more stroke. On FI I would favor a square build or big bore short stroke. Aside from that you would be better served just doing rods/pistons and moving to a larger blower. That setup will walk all over a large stroke small blower combination. Talk to ya boy Pray.... jm2c
