If it really is a new engine ( that is, a new build-up that hasn't got a
racing history of the actual parts inside the engine) with 8 races, then I
personally would do the following:
1. Hot leakdown test.
2. take the head off, inspect the bores.
3. split the engine off the tranny, inspect all the journals, install new
bearings. I don't like to put back old bearings even if they look great, I
have a superstition about bearing crush.
4. Pull the cam out, inspect the lifters and cam surfaces.
5. inspect the transmission, make sure the synchro surfaces are ok.
6. change the oil pump
7. change the rear main oil seal.
If all that's good, then I wouldn't actually rebuild it. This qualifies as
a 'freshen". Rebuild would include honing, rings, crank magnaflux and
polish or grind, resize rod big ends, timing chain, valvejob.
If it's a new build of a racing engine with history, then I'd look to get
about 50 hours out of it, and you probably have about 20 on it. At 12:1
compression, you have a fairly mild Mini race engine, so you would be pretty
safe.
