I am building a 1974 4 port 13b for my 1974 repu. I am looking to get between 300 and 350hp to the wheels, running 10-15 psi. I have a whole selection of housings ranging from .60 a/r and up on the cold side and .84 to 1.36 a/r on the hot side. I would like to pick a combo that will be quicker spooling and have a broader power band. The engine has a medium sized street port on the intake, and the exhaust is opened up a fair bit.

 

How about a 0.84 divided, P trim wheel, with 60-1 compressor and T04S cover?

 

my smallest divided hot side is .96

 

Isn't the .96 a non-divided or did it come in both?

Anyhow, anything from around .84-1.00 will probably be good with a P trim wheel for the hot side.... as for the cold side, I'd definitely say 60-1 compressor with the T04S cover.
