Think I'd still pull the entire engine down. Too much debris for my liking.

None of this makes sense to me. I've had slip joint headers that showed the black marks from exhaust exiting between the joints....never smelled anything, or heard leaks. IF there was anything to hear, it was only at full throttle, where I couldn't hear it anyway over the carb and/or exhaust note. I most definitely never smelled like exhaust from driving, or smelled it at all for that matter.
I agree as it doesn't make any sense to me either. Something under the car must be missing, like a shifter boot, or holes in the floor pan are allowing the smell in. Maybe firewall gaps yet airflow should not allow it. Maybe test the cowl by using some blue painter's tape to seal it off 100% as see if that makes any difference.
Hey, Bill! Can you repost a few of your SOHC spring vids again? They were so cool and with the passage of time, I'll venture newer members never saw them.
Sure! Give me a couple of days to get some family out of town and then dig the videos up.
My old 390 built in the 80's has/had the TRW 2292F 0.030" pistons.
The skirt clearance was 0.009"
Ran that way for many, many hard run miles.
Had 5.14 traction lock rear - saw plenty of rpm on a daily basis - was my daily driver through university.
The 390 sat on an engine stand for 25 years - took it apart last year. The piston skirts look brand new!
A very cool project and I feel fortunate to be on this list where I get to observe the progress and technical details.
I wonder when - not if for sure - we'll get to the level where we could 3D print cylinder heads in aluminum, then heat treat to the required level, then off to machining. The equipment cost is going to preclude that for a while I'm sure. My work has a small 3D metal printer with a build envelop of 125mm ^ 3 and the est. cost is around $500,000. Could maybe print a cylinder head for a 110CC quad
so it is normal to hear some noise while turning sharp? when going straight it seems to ride better and stays very straight when you go faster.
Needle n seat assembly most likely stuck, clogged or leaking by the o ring .
