Anyone want to do some figuring? (roller rockers)
Eventually I'm converting a 3.0 Aerostar into a 4.0- I have my work cut out for me. I have to find lots of things, but that's not my topic.
I'm not going to just simply put a 4.0 back in there. I want to modify the engine some while it's out. I have a rocker arm set from a 390 that I found, and I was looking at that- and looking at the pics of Delta Cam's replacement shafts.
What I'm wondering, if anyone can help me, is if you can give me some measurements (as accurate as possible) on 4.0 rockers. I want to compare these to the 390 to see if roller rockers made for FE blocks will work even if I need to rework the shaft mounts and install a thicker shaft. I think it's doable, but will likely take some machining.
I need measurements:
Diameter of pushrod cup
Distance from center of cup to center of shaft
Distance from center of shaft to center of tip
Distance from center of cup to center of tip
Diameter of rocker shaft
Thanks for the help, and as soon as I have a 4.0- say 6 months or so, then I'll start working on getting it together, and be sure to let you know if if can be done.
