Crate Engine Smoking
Recently installed a Blueprint Engines 383, after going through the initial procedures prior to starting it.
Upon starting the engine everything appeared to be normal at idle speeds around 500 rpm, however when elevating the rpm to over ~1500 a white smoke would begin to puff from the exhaust.
Is this something I should be concerned about or is this expected for breaking in a new engine?

Left?
Right?
Both exhausts?
Does the auto/transmission vacuum line to modulator have transmission fluid leaking into the hose?
Does the white smoke have a "sweet" smell (antifreeze-coolant)?

After letting it sit and starting it back up and ramping up to 2k rpm the right side began to smoke while the left side had no smoking. However I did not let it run long after I noticed the smoke on the right side, 15 seconds maybe

The previous engine did have a piston failure on the right side which could be the reason it’s smoking. And there may have been a slight amount of water in the mufflers from sitting out.
I may also pull the plugs later
