Finally got to test my winter/spring/summer project.It's an 18'cole ('76)with a 468 BBC,aBerkley 12JG ride plate, shoe, droop snoot, wedge, blue printed bottom, place diverter etc.The motor has a strip dominater intake, holly 800 dp, oval port heads,and log manifolds.Cam is 518 degrees @ .050 with 501 lift.Now for the questions. I have a slight porpise when i trim up about half way.To much wedge or lose the droop? How do I figure out whitch impeller I have? {at around 60 MPH I'm pulling around 5200 RPM}.Where should the ride plate be set?I'm feeling the need for more speed.But it sure is fun to drive.
