while im in there question
planning a cam swap for the winter.
btr cam 38% fuel lobe, Johnson link bar lifters, btr platinum double .650 springs, .080 wall pushrods, che trunion kit, lme complete vvt delete , katech high flow oil pump. by the time I start all this I may have about 25k miles on the motor. would it be prudent to replace the crank and rod bearings " while im in there?" if the answer is yes can I use oem bearings and simply replace them or is it a more complicated process than a garage diy guy should do? with the mileage should I just leave them alone? only looking for 750-800 wheel not shooting the moon or 1200 hp.
also what is the best way to clean the piston tops and head surfaces when the motor is apart? I know green pads are a no no.

Do not touch the bearings. I wouldn't clean the piston tops either. I would just clean the mating surface of the head and block with brake clean on a rag before assembly.

I could be wrong, but I don't see why you would be removing the heads to install these parts? I'm new to V8's.

Gotcha, I'm used to 4-cylinder turbos. This is my first V8 and my first supercharger. Either way, I still wouldn't clean the piston tops or worry about the bearings. If you have metal flakes in your oil, then I would worry about the bearings. I think you have a higher chance of bearing failure if you swap them out, then just leaving them be. Lastly, I would add ARP head studs to that list if you didn't already plan for them.

titanium rods yield titanium dust that scores the bearings. Won’t see it in the oil but it’s there. Already have arp head bolts

interesting. my ls9 motor from the zr1 had Ti rods so I was assuming the lt4 would as well. looks a lot like a flow formed wheel lol.. defiantly will be doing bearings now.

To your questions, at 25k miles with strong oil pressure I would leave the short block alone. With the changes you are making and depending on how you drive it, chances are you will be in there again before the bearings need work.

1 and done on this motor hence the question. 750-800 whp is all im looking for. already had 1000 whp cars for me the sweet spot is 750-800. runs fast no issues. so cam and internals related and im done as long as the bearings are ok with the mileage . seeing these powder rods doesnt leave me with a warm fuzzy though rather see Ti or Carrillo rods was figuring the oil pan is already off popping the rods and crank out is no big deal . wasnt sure how long the bearings are good for with the added power over stock
