as said...215 isnt HOT for a Pontiac....but its nice to get them to 190-200 in hot summer days...the list is long how to get there, Id start chiecking if it needs the 'fillers (3 sets) if a 400 or AC car...then timing, carb setting , water pump flow, raduiator on and on......but unless its 225-230 or over I wouldnt worry too much....
Vikki is an old cuda gal too.... Lee , have you checked w her on that part?
