Jim,
10.5 to 1 compression would be a bit much for pump gas these days (IMHO).
The unmodified 1275 would have more torque across the board and would be a
lot snappier during everyday driving. Horsepower is a function of torque
and rpm, while torque is the actual power delivered at any given moment.
Although torque can be increased a little by certain mods, reaching an
equivalent horsepower to a 1275 with a 1098 would require much higher rpms.
Unless you plan to spin that 1098 high, you would probably be more
satisfied with the bigger engine.
