Short history:
1970 302 block. Stock crank, rods, bolts. Purchased the JEGS street/strip pan (6 qt #50290) with matching PU tube (#50295) supposedly able to clear up to a 3.55 stroke when used together.
Here is the issue:
With a stock oil pump installed and this tube bolted on, the #4 rod bolt SMASHES the PU tube! I measured screen to pan floor and it was great. I exchanged the tube for another one from them thinking the tube might have been mis-manufactured and got the same result! With the new tube I am able to 'space' the mount tab with a couple washers to clear the #4 swing, but need to clay out the screen/pan floor distance to see how it is.
Why the heck is a stock cranked/rodded/bolted bottom end hitting a PU tube that supposedly clears a bigger stroke?? Thoughts? JEGS thinks I must have erred somewhere, but I fail to see where. I mean, the rod bolt is making contact about 20 degrees before the bottom of the stroke (red arrow) all the way through the yellow arrow. I don't get it.
