HRP TOP FUEL STAGE-1 ENGINE CASE ASSEMBLIES READY FOR DELIVERY
We now have our Stage-1 engine block assemblies complete and ready for immediate delivery. HRP Stage-1 engine blocks take the typical XL style camshaft/lifter arrangement. The rotating assembly can be the typical crankshaft/rod arrangement used in the Prp/Overkill engines (full 360 degree cranks) as well as our Porkchop style crankshaft. We have modified the crankcase scavenge system for better evacuation of the crankcase. Stage-1 engines can be used in either wet or dry top end configurations.
