As far as the power band I think they were all low RPM performers, under 4200 RPKM for peak HP and I think around 3200 to 3600 RPM for peak torque, maybe I'm wrong on the numbers so make sure and check them before deciding twocents


You have a pretty good memory. The set I want are the long ram divided runners the entire length. 30" runner length including the intake runner in the head to the valve. They were tuned from the factory for torque between 2400 and 3200 rpm with the peak at 2800.

Just about perfect for a truck motor that will actually be doing some light towing.
