What would cause the over heating

[elev8_dude]

Trouble in the sunshine state (FL). Now I know the temperatures here have gone up, however I recently went from dual 40' to dual 44 webers and on the way home my engine shot up to 240. I have always ran at a max highway temp of 210. I checked the oil, plenty. I have a full flow system also. The only thing I can think of is the oil is shoot (crazy idea), The new carbs got me running to lean or my oil pump is freaked up. This is brand new since the new carbs. I'm lost, as usual. Just concerned cause my engine is a 1915cc and I'm in the dead mid of summer.

P.S. Could timing be a factor. I didn't change anything on my MSD distributor when I switched to the 44'

Help before its to late...
