Not Ranked
Fordracing F I believe it was 559 RWHP. I am running a solid roller 268 272 Duration, 731 722 Lift (4 7 swap on firing order),112LCA.
Chas 4150 with a 1.25 drop down base. I have about 1/4 or less before it rubs.
Brent u will have to notch the block on a dart. I do not think so on a world block. Why would need to do any work on the oil pump if using a dart block (oiling is very good)?
I am using a mellings HVHP pump with oil cooler (Cold PSI 95 cold, 45 hot with 5w30). did change the spring to get the pressure i wanted but thats it (.0025 on mains and rods).
Brent thanks for taking the time to answer questions.
