They certainly did dress out nicely. The Banks headers definitely made the transitions down the the spark plugs easier.

I think I'll go ahead and order one of the wiring loom kits.

Thanks!

Brad

Getting closer to the next engine restart. It's been way to long since I ran it last but to many things kept getting in the way of progress

I pretty much finished up the exhaust system installation. Just one a large worm gear hose clamp to hold the muffler to the upright and add water and it should be ready.

I might try and add a 45 or 90 off the top of the muffler but I won't hold off starting the engine just for that. Hopefully a local muffler shop can bend one for a reasonable price.

Don't forget the fire extinguisher

That is a pretty impressive looking motor stand good luck with the test run

I've probably spent way to much time and money on the stand but its been kinda fun

The 30 minute break-in run is now complete! Took a few minutes to get the engine started again but a little gas down the carburetor and it fired and stayed running! Best part is there was no drama with the spark plug cables so I didn't need the fire extinguisher that I had handy

2000 rpm break in run

900 rpm idle run

After taking a break I set the timing and tightened the alternator belt. Tightening the alternator belt got rid of a weird harmonic knocking sound that I heard during the break in period. The alternator is charging at a nice 14.2 volts. It starts right up but and sounds good although it does have a very mild loping at idle. Not sure if that's the cam or carburetor adjustment.

I have a wide band O2 sensor in the exhaust and at higher rpms it drops down to 13.0 to 13.5. At idle it stays around 14.4 and 15.0. Never used a wide band sensor before so I'm not sure how much it should bounce around while running.

Needless to say I'm so glad to have the break in period completed

Next step is to start installing the TBI components and do another test run. That's going to take a month or two.

Nice. I bet the lack of drama was quite satisfying. Sounds healthy!

It was definitely anticlimactic

Sounds great you should bring it to Pen Wood and more test runs

It's tempting but I've got enough other stuff to haul I doubt that I'll have room

sounds real nice. The 900 rpm video is private, who knows what really happened

My o2 sensor readings vary a lot, depending all the different inputs. It does settle back to ~14.7, but most important it stays close to that under load and at highway speed. During deceleration you may see it go real lean, like 17 and 18 for a very brief moment.

Interesting, mine gets rich on deceleration. The reading is constantly moving when driving down the road so I'm not too surprised you saw some variation, even on the test stand.

I guess I won't worry about the O2 sensor bouncing around. I wasn't sure if it was the test stand and the fact the engine is pretty much hard mounted to the stand.

Most of the time it was less than 14.7 which I believe means I was running rich. I think for a break in run I'd rather stay a little rich than to lean. I'll worry about mixture once I get the TBI system installed.
