New crate motor woes
I'll be interested to see the leakdown results. I'm thinking more the final finish on the bores was a little rough, and the rings havent fully seated yet. They may get better. They may not. I re-ringed a 383 last year because a wrong ballast resistor and confused owner washed the rings out of a new engine and they never seated well. If the 2nd ring sdoesnt seat, you will use a lot more oil than "normal". I also have an Indy crate engine with 5K miles on it that smokes at almost all times. The rings never seated in it either because of the poor Demon carb's state of tune as delivered by Indy. That's a $9500 engine that smokes at 5K miles...I see a lot of engines in posted pics that have the wrong final finish on the bores for moly rings.
