This is our new version of our former #HP45M. We have swapped over to the later model Gen V 1991-1995 engine blocks as the foundation which has NO provisions for a mechanical fuel pump. We have also swapped over to a Hyd. Roller Camshaft/Lifter package for better streetability and a little more power! more info
