I'd guess about 125MPH at 5700rpm's or so? The issue will be the front end wanting to lift giving you little or no steering. Been there done that! :scared:

Assuming you take the engine to 6000 rpm you would theoretically be doing 166 MPH
I know the carb is too small & no clue on intake or exhaust but I would guess you will be lucky to get to 135
