Looks good! Better hurry up, racing season started already.

My friends and I, all have been running the Hughes locking dipstick for years. Got them from summit.

Just a quick update on this. He got the modified bearings from 440 source and it didn't make a difference, like I suspected. I ended up cutting the radius off of the back side of the slinger and it seems to be good now. I haven't had time to go and work on it but he set the crank in and it seems...

Wow, that was a kick in the nuts. John, you sure are missed.

As stated before,no.

I will have to take a look at that. Thank you for your suggestions

It's hard to read that but is it saying that the o.d. of the flange is oversized? Like it would need turned down to fit properly?

I could chuck it up and cut it but didn't know if that would weaken the crank any. I think that once the crank is able to move back, it will solve the thrust issue.

Is it normal to have to take .030 off the one side of the thrust surface? What about the excessive clearance on the opposite side? I've never had to take that much off before, that's why I'm asking.

With the thrust installed no, the bearings aren't hitting the radius on the crank, just the crank rubbing the block. That's why I think the block need clearanced because of the crank moves forward to clear the block, then the bearing is just touching the radius on the crank.

Like I said the ones that 440 source modifies are on the way. As for scat, they say that it just uses a p-bearing, which is what those are. We will try them but just trying to get a plan together in case that doesn't work. I think I .010-.020 chamfer on the edge of the casting will get taken...

They are regular berings. Unfortunately the kit was shipped without main bearings but the rod bearings were in the box. Summit and scat were of no help to say what bearings came with the kit. The only chamfered you can get are ones that 440 source puts a chamfer on with a fixture they made to do...

Yes, that would be the correct measurement on the thrust. With the thrust in place there is no movement because it's hitting in the block. Those pictures are with about .005 lapped off the back of the back of the bearing. My concern is if I keep lapping material off the bearing, the front side...

Here are some pictures With thrust installed Gap flavors front Bearing location with thrust installed Thrust bearing removed Removed, now has clearance Bottom thrust just to show how much it needs to move

Yesterday I went to help a friend assemble his 383/432 build. I put the bearings in to check clearances and set the crank in the block. As soon as I set the crank down I noticed it was tight. The radius on the oil diverter(or whatever it's called) that's built into the crank is hitting the...
