Here are the detailed build specifications sheets with all the tolerances.

You should also make sure that total advance is correct, take it to someone that has a SUN distributor machine that can check everything.

I have been gathering NOS parts to refresh my K code engine, its been a while but its now complete. The dyno runs were completed this week, we did have a little issue with the carburetor as secondaries were no opening all the way none of us were Autolite experts so we had to continue with what we had. The refresh was done using New Old Stock and orginal parts except the cam and lifters (came from Howards and as close to orginal as we could find for a flat tappet mechanical cam). We were using the Autolite C40F-AL Carbuator . The final timing was 12 degrees initial and 32 total advance. The results were 294 hp @6000 RPM and 301 lbs torque @ 4000 RPM. These are NET results not GROSS as we had water pump and all pullies and alternator hooked up. We used all NOS internal engine bolts. Crank was not turned, engine was balanced, The engine is stock no modifications done to heads or block or carbuator. Plugs were Autolite 45, fuel was 92 unleaded octane.

Not sure people are interested but here is the dyno sheet. We did not take it past 6000 RPM as we saw the HP and Torque werre falling off.

The engine was built with tight tolerance, no issues other than the acting up carb, we checked the filter and lifters after and nothing in filter and lifters were still dead on gap

Dan, thank you for the response.

Since someone put a different carburetor on my HIPO engine, so original is lost, what would people recommend as a replacement as I will not spend 4K on a original one but would like to replace it with some sort of autolite 4100 instead of the holley that is on it now.

I am unclear as to what you are showing us in your hand. The C4OZ rod bolts have a rectangular head, the same as the original bolts in Hipo rods. The used bolt in your hand appears to be an ARP replacement which fit both Boss 302 and Hipo 289 rods. Maybe the original bolts were replaced in a former life with the ARP bolts. I do not understand the C1AE bolt package as they are for 352 and 390 standard engines. Those bolts are 3/32" longer than the Hipo 289 bolt. The C9AZ nuts are correct.

C1AZ-6214-A were also used in in 65/66 . These may have been used by other engines also. These are not ARP bolts the bolts I have in my hand are C1AZ-6214-A. I'm just trying to replace what the engine was built with. My engine did not have the C4OZ-6214-A. The engine has not been apart prior from what I can tell.

Found what I was looking for

thank you fo reply so you know which Carter this was this a replacement for ?

Starting the refresh of my hipo engine and seems I have a non-hipo fuel pump but can't find out much about the pump that on the engine now. It has a tag of 6838

Refreshing my 66 HIPO engine and looking for a set of rod bolts C4OZ-6214-B or suggestions on what can be used instead as not wanting to reuse the old bolts. I don't really want to use boss 302 service rods as an option as I would like to keep this refresh as original as possible.
