These heads are being done for a new motor my uncle is building. It will be a siamese bore tall deck 59* r3 block. It will be 439ci. 14-1comp, roller cam on alcohol. It will be going in my new drag car. A 69 dart 3000lb, ladder bars and coil overs 29.5x11.5 tire. Converter will be bought after dynoing, 727trans and a dana 60. What do you think it will run at 200ft above sea level.



I would bet that seeings how it is a dart it will only run mid to low 10's on a good air day. If I was you I woulnd't waste my time or money on a dart. Just my opinion.
