Hey guys/gals, seeing if anyone has run a combo close to this setup.

I know how the 68RFE trucks run but my truck with the Aisin is uncharted waters for me.

Anyways I am looking at running a s467.7 second gen swap, but I am unsure if I will be lagging a lot with the lower gearing of the Aisin or if I should drop to the S464.

I will be staying stock fuel for a while until I get the trans built by Randy’s then maybe 100hp tips.

Truck is my daily commuter, may tow heavy 2-3 times a year(15k lbs).

Will also be doing studs springs and push rods at the same time.

turbo specs
s464 63.5mm compressor 74.3 turbine and a .90 ar t4
or
s467.7 67.7 compressor 83/74 turbine and a .90 ar t4
