65f1 is done at 80-82#/min
62f1 is capable of 70#/min
Yes it’s capable of more power.
Depends on exhaust housing too... Garrett .63 on 65f1 wheel WILL NOT be capable of 800hp at the flywheel. With a .85 housing it’s capable 800-820hp with the right compressor wheel on the right car.
Not 100% stock...has an old Comp 206 FT cam and the proper springs with arp head studs but everything else is stock. I'm not sure what the rpm range is on the 206 cam but I feel like I could raise the shift point up a little from 5100.
