I am considering install of a Broad sump engine in a short neck Tonti frame . Asides from the obvious ( dizzy hole and dizzy gear on cam, Roper plate, oil cooler ports) is it bolt on or are additional mods needed ? I will be running carbs and dizzy (unless I can get my hands on a complete EFI setup) as I already have some Malossi 41's . I am sure other folks on this board have done something of the sort in the past, so ,if you have or know something on the subject, please fire away.
