Don Terrill’s Speed-Talk

Hey guys,
Here is a link to another of the AERA's free webinars. This one is on the 6.4 engine failures and fixes. All you have to do is register for it. You do not have to be a member.

What intake ?

How often do you change the oil in the bike ? Maybe once a year ? Is it worth taking a chance ?

not sure what the "626" area is. If you are close to him Mike Lewis will be good https://www.lewisracingengines.com/

Cutting the od of the counterweight would seem to be most effective at removing weight and I suppose the same theory would be in effect since the counterweights are in pairs. Making them thinner would probably help windage but not sure what the trade off would be. Hopefully Dave will chime in, he ha...

Unless you have another reason to cut the counterweights I would have it reground first and then checked. Cutting the counterweights is liable to require adding weight back to get it to balance. Unlike a V-8 crankshaft yours has two rods directly opposite of the other two so I don't think your modif...

If the bearings have sufficient crush, why not simply use a set of .001 or .002 under main bearings?

If the bearing bores measure what he stated then the bearings will definitely not have enough crush.

Yes I measured it and micd the crank journal how could I come up with the clearance without doing that ? Plastigage ? You would be amazed at how some people check it. I had to ask :) It was 2.6440 to 2.6450 after the machine work on every journal after machine work. That is pretty ugly :( :(

Dan I agree completely, the hack job the machine shop did was pretty ridiculous.

How do you know that ? Have you measured the main bearing bores with a bore gauge ? How about the crankshaft journal sizes ? How about the bearing thickness ?

Unless I misunderstood the original question, the answer is in the last column labeled "max length".

Correct Might be confusing if you dont do it all day long.

We need to know the amount of offset that SBC connecting rods have, and the width of an un-chamfered Clevite 1.889 Honda racing rod bearing. Have looked everywhere but both are hard to find. Thanks in advance for any help you can offer. I am pretty sure I am looking at the right one. CB1665HD .896 ...

It did not cure at all...3 days after install it was still “liquid”. How do you know it didn't cure ? Did you take the bolts out and look ? It only cures where there is no oxygen. It will never cure out in the open. Put a few drops on something and let it sit out in the open. It will stay liquid fo...

Just did it again to me. 3:50 pm approx Looked at two or three threads and then Bam, no more I attached another tracert

Is .093 a problem ??? If you were using a stock type flex plate before there is a good chance it was not very straight anyway. I have always figured that as long as there was some clearance it was good to go.
