Well a day of tinkering in the shed.
Honed the bores, fitted new main & thrust bearings, re-fitted crank & oil squirters. Also modded my GT Turbo engine bracket to fit the F7P, 95% there, just needs a few final touches & I'll get another to mod so it's 100% for the final build.
Got my oil drain but need to get the right size drill bit & a 1/2" NPT tap before I go on with that. I'll have a go at fitting the new piston rings over the next few days as well & then I can fit those up & re-fit the oil pick up & sump.
