DOMINATOR SERIES BLOCK - 4 CYLINDER
The race engine you are looking for. The thick Darton Sleeves we press in help this block take the high boost pressures & nitrous use with ease. It is a proven winner with the precise machining and upgraded internal parts that make up this monster. There is a billet crankshaft avalable.
