My case and crank just got back from Ollie’s. Very excited to build this engine!

The guys at Ollie’s decked the case and line honed the mains back to standard. They also grooved and cross drilled the crank. Lastly they balanced everything to within a fraction of a gram. I plan to rev to 7500 so the crank needed to be grooved and cross drilled from what I hear. Maybe would have been a good idea to shuffle pin the case but I think it will be fine for street use.

I’ve been measuring everything first. Tedious but I’m not going to rush this build. The main bearings from Porsche very very consistent. The Clevite rod bearings were just dead on. Probably more accurate than my measuring.

Everything looks great except I may have too little clearance on the rods. My clearance is coming in at about 0.001” and from what I’ve heard it would be best to be at 0.002”…maybe even a little more given that I’m boosting the engine. I’ll make some calls tomorrow and see what the pros think. Getting a thousandth taken off the rods is likey to take a few weeks…

I did drop the GT3 oil pump in to test the clearing that Ollies did. Perfect!
