Horsepower TV - 2006 LS2 Nova Gets Bottle Fed was released on: USA: August 2007
70 nova's never had a 454 in them and the horsepower rating would have to be assessed from the year the engine is and if anything has been done to the engine other than being stock.
The 69 Nova had the small block 302 c.i.e.
396 big block
