Bringing this one back from the dead...
After an embarrassing amount of time I finally have this engine done, installed, broken in, tuned and with 1k miles on it.
I ended up with NOS R&R steel rods from a fellow Pelican from a project that changed direction. It is a shame that they no longer make them as these are some of the best I have seen, and I have seen a ton of connecting rods. Weight was lighter than Carrillo, weighed identical to each other and big end sizes where spot on.
The engine went together with out any drama. I used main bearing clearances that may seem out of place compared to what I have seen discussed and rod end bearing clearances that are near what I see discussed here. For the time being I will keep these numbers private
but I do love seeing the oil pressures and temperature data I have collected over the summer.
Quench, or "squish" was set at .030", compression was just shy of advertised 10.5:1 from Wossner as expected. The pistons measured great and where identical in weight.
DC60 cams where degreed at middle spec and I used mechanical cam chain tensioners with racing chains. I have no issues with the added maintenance and slight noise during warm up.
I didn't document a tone but I will share some photos.
Rod differences.
Bare piston weight for Wossner's 95mm offering. I didn't take any photos of the pistons after some modifications, but have included some of the first mock ups.
Here you can see the cylinder 3 thermocouple wire and connector and the stock port heads.
Just a sprinkle of off topic... You have to love Open class Pinewood derby racing, I love that our troop has a limited rules parent's class. This one was good for a significant bump to the track record.
