Maybe I'll have to focus a little on the first issue...

BTW, what color and any clues on what the mods list will be looking like?
Probably hard to guess the mods yet, until you get to know the N* like the L67.
Anyhow, be sure to keep us updated on what our speed-demon GXP is progressing.

Maybe you should forget #1 Scott and figure out where the cruise control is

Getting back to the differences in the two motors.
After a bit of digging the cylinder heads are diff. the caddy gets 2 (1.425in) intake valves same as the gxp but the caddy gets 2 (1.42 in) exhaust valves while the gxp only gets 2 (1.102 in) exhaust valves.
Also cadilac has a cam shaft posistion actuator system that allows the ecm to adjust cam shaft timming of all 4 cams while the engine is running, not the gxp.
I would think these two facts might add up to the 25hp drop in the gxp?
