Just curious, why did you go hydro boost over manual brakes?

More stopping power with the hydroboost. Should compliment the larger brakes (when I get them) and it clears up some room I needed.

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

Eythlene glycol and phosphoric acid then hot soapy water will make it spotless

To keep the pistons cooler and compliment the thermal barrier on the crowns I ordered some poor man oil squirters.

I’ve seen those. Curious how they work. What oil pump and bearing clearances do you have? You may need more pump.

Not sure that will be enough pump on an aluminium block with squirters and those clearances. Remember they will open up when hot.

I have a 10296 also.

What pressure do you see warm idle and max psi under wot?
I got the 295 (high press reg volume) and have alot of remote stuff and it crosses my mind if i made the right choice.. but i also have iron block so pretty much stock clearances
