blaster motor is kickass, but honestly are you even serious about thinking of installing a motor thats almost 500cc's. Not even kinda overkill its WAYY too OVERKILL, kinda sapprised someone would think of it, do u realize the work involved in installing it or the amount of vibrations that thing would put out. a 250 motor would be more relistic, im sorry a 490 motor in a blaster would suck it would be like intalling a ls1 in a mine cooper it would be fun but lets face it would suck.
