Yeah I understand it moves more air and the blower is no joke, just interesting results. You have to match engine displacement with blower displacement or the mis-matched component must work harder. Kinda like putting a P1SC on a good flowing 4xx+ ci, the blower is being spun ballz out and nowhere near efficient.
Any other changes to the car other than blower swap? I assume pulley change as well?

Nothing fancy just a Yank pas 3400. When I put in the trans I was on stock bottom end with a procharger and planned on going with a 370 down the road. So I had him spec the converter for a 370 with 15 psi from a procharger and a general cam size that I told him I planned on. I ended up going with a 377 LS3 and 18 psi with a little bigger cam than I originally planned. It works good though for a heavy GTO in a street car. Really nice on the street.

That car must be loads of fun. I had a 3000 stall on my 5.3l but it was more like 2200 and with the 4L80e it was just awful. Couldn’t get under a 2sec 60’ even with all that power. On the 408 I’ve got the 3700 stall from Circle D coming. I’ve heard good things so I’m hoping it works well.
