I ran it total for about 5 minutes at around 1500 to 1000 rpm to reacquaint the lifters and cam after they had been sitting since they were broken in on another engine. I thought I heard valvetrain noise, but I don’t believe it is after listening around the engine. It has pretty much always made that noise. I now will have to warm everything up and tune the idle. I’m happy having a 113 LSA over the 109 for now, cause it apparently will be much easier to make idle. Not to mention, it sounds pretty nasty.
Only weird thing is adding 13* more intake duration at .050 so it’ll hopefully feel a good bit stronger. And it’s supposed to rain for two days here to maybe wash the salt off the roads. If that’s the case, I’ll be cruising on Sunday. I still REALLY need to do the trans and rev limiter work before I beat on it though. 450 hp on stock stuff won’t last forever as it is.
Bad news: cylinder 6 exhaust pushrod is very loose in there. What’s the chance that a lifter isn’t pumping up? Edit: It appears the pushrod had just loosened itself all the way.
Ok that wasn’t the case. I still hear a top end noise and have pulled both valve covers and am about to adjust every pushrod
John. You hear a tap everywhere on top end? In both videos everything sounds great. Really good. How's your oil pressure. I'm sure you cleaned the lifters. Let us know. Any chance from swapping and machining push rods are too short? Wait, you have rollers or adjustable pushrods? Got Zinc?
Oil pressure is great as usual. Lifters had oil pumped through them. I have Smith brothers adjustable pushrods and just adjusted all 16 another time, rotating the engine 1 full rotation. Plenty of zinc, running a mix of Valvoline VR1 High Zinc 10w-30 and 20w-50.

It's too early to tell, those videos were with NO tuning at all, just to get it running. So once I do my diligence to get it running properly I'll be able to let you all know the real song the 113A will sing.
I took the liberty of sleeping in this morning. Don’t worry, won’t happen again I’ll be checking the second revolution of the engine this morning and will then fire it up once more. Several of my family members have said the exhaust is louder, not sure if I believe them yet. However, when the vacuum advance was added, the exhaust note did in fact quiet down. Also more good news, the vacuum gauge read rock steady, unlike when I thought I had a vacuum leak, when I was tuning at was able to pull 12" of vacuum at an 850 rpm idle. There's likely more work to do, but so far I am pleased.
