If the supercharger washers have been changed from ceramic to steel and they have never ran synthetic oil you should be fine.. If the ceramic washer has failed before replacement walk away because that motor will be a time bomb.
The only way to get all the ceramic pieces out of the engine is to do a toal teardown.
New crate motor $4500
Super fast out of the hole and very stable at speed even in the rough stuff..
if you drive it easy you can go all day on a tank of fuel...If not be prepared to add 70 litres of premium gas in a couple hours
