Not sure cold start counts. Appears choke opening wasn't adjusted to match throttle opening, from fast idle cam, in that video.

This thing knocks no matter how it idles. Cold, hot, smooth,...

Not A Miss/Skip

Appears to have one cylinder not hitting with the same amount of punch as the others.

The idle mixture screw over #1 and #3 will be a balancing act at best with the PCV hooked like it is. Make #1...

Was the slot dead center of the shaft?

About the skip/miss

With the PCV plumbed in the middle of #1 intake runner....It's going to have a lean miss. The closest idle mixture screw would have to be backed out for it to hit and would make #3 run rich....

I think short head pipes vs. duals out the back is the difference with that.

Just way too loud in the dyno room to hear the noise. Not being able to hear doesn't mean it didn't exist.

32° total @ 3,500 rpm's. 15° initial.

That goes right with your earlier post on total and distributor advance.

My thoughts on that,

.001" clearance during assembly wouldn't be there with the engine running on the power stroke.

Messy job but I think I'd have to get the palm of my hand on the rockers just to see before swinging the engine to look inside.

Definately needs ruled out before the exploratory surgery begins.

In the dyno video it appears the engine had short head pipes ONLY on the exhaust manifolds. Engine would have been way too loud to hear the TAP TAP TAP.

Of course not. I think that posters rant and the follow up statement is the only way he knows to say 'i don't know'.

How long does it take for that to happen? The bad gas sticking a valve.
Carb got primed, the engine fired right off and the TAP TAP TAP was there.
That would mean bad gas sets up faster than super...

No "BUT" Next Time

Next time you do that..... scribe a mark on the distributor base and block. Also note where the rotor button is pointed. Then you can stick the distributor back in "exactly" where it was. No need to...

Pick up a 3/8ths line maker and carry drill, bits and taps when you go.

Close fit on the TII but there is enough room to run the PCV to front center plenum.

I don't understand that. When numbers are "lower" on a thermometer here in GA it means temps are cooler. Old dyno sheet shows 85°F and the new one shows 83°F. Baro close enuff but it was less humid...

Nutshell?

In a nutshell the OP doesn't know how much torque or HP the engine originally made "as delivered". Paul never shared that info. He did post that it made 517 HP, with the 870, "BEFORE" it got jetted...

Good For Him!!!

Anyone that says "you can't teach an old dog new tricks" would be wrong on this one.

I'd be willing to bet Koerner Racing Engines is doing this on every engine they build now.

What brand and part number was the bogus oil filter that caused all this collateral damage?

5W's (or at least a few of them) should have kicked in here, before the engine went back together/parts swaped.

If lifters were in it, it would have built oil pressure all the same.
