Thanks yeah not hard work just time consuming
So close to being finished with the crankcase. All bolt holes and hard edges have been chamfered. With aluminum flexing and expanding so much the chamfer on the bolt holes will help prevent the studs pushing up on the edge creating a micro crack that turns macro...main caps seat properly...stop a burr from forming by the stud pushing on hard edge that could prevent the head gasket from doing its job etc etc
Porting front oil crossover....I’m softening the edges on all the oil passages

It’ll clean up easy with some ethylene glycol and hot soapy water. I’ve got more time than money and having fun tinkering around.
To keep the pistons cooler and compliment the thermal barrier on the crowns I ordered some poor man oil squirters.

Because hydrodynamic films are basically impossible to create between parallel flat surfaces. That’s one reason crank thrust bearing faces cannot support heavy loads. The fluid film is squeezed out of the annular contact. Now to file feed grooves to them. Some spiral or chevron grooves actually promote a inward (non leaking) hydrodynamic film to form.
Camshaft end play is roughly .003-.004”....within the spec of minimum and maximum of .001-.012”

Finally got around to coating the rest of the valvestems with Mircoslick. I had plenty of Mircoslick leftover so I blasted and coated the tops of the seats and bottoms of the titanium retainers.
Scroll down to page 16 and you can see the testing Cerakote did with their thermal barrier coatings. The C-186 Piston Coat I’m using performed well reducing temps by 81* with internal temps of 1706*. The V-171 Turbine Coat did even better in the testing. The turbine coat reduced temps by 185*!

Great job on the bottom of the lifter bores. Its hard to believe a shop would send out a shortblock with jagged edges like that. WTF. I do cross my fingers for you when you put your engine together that all these film thicknesses don't stack up and cause problems. I know if I tried doing this, I'd **** myself hard.

Yeah I’ll be checking installed heights for the springs again. The valvestems fit smoothly as before. Working on finishing up smoothing and cc-img the chambers today so I can coat them when I get I chance. I’m also working on designing a “splitter” for the Whipple lower manifold. Started port matching and smoothing it already.
