This is my 1979 Monza Spyder. It was built in May, with a v-8 out of factory. I was told they discontinued the v-8 monza's in march. We will have to look in to that more.A while back we bought an all aluminum Griffin radiator. This cost us in the area of $450 brand new. We got a special from the boys at v8monza.com. This is set to handle in the areas of 600hp.
