I have a YF2100 on my 235 with 848 head with a T-5 transmission behind it, and I do not need any more carburetor than that. I reach maximum RPM (screaming, as they say) quickly with every gear shift, and have plenty of gas pedal in overdrive at 65 MPH. I have never tried it, but I bet this truck will do 100 MPH.
