just dropped the cummins off at machine shop
 

Now they are going to bore the block .30 over and ground the crank .10 so with the block being bored .30 over what will the displacment be?

just did mine to .040 over bore, decked and line bore check, and the crank .010 on rods and mains, and bored a hole to the main oil galley by #6 to bring oil to the rear as well to help it, been building them for a while now for performance this way, it's hard to notice a lot of displacement diffrence with a Diesel with how much torque they already put out, :tu:

also pretty sure you can only bore to .020 or .040, on the block, just saying,

Well i found a total rebuild kit and it and i can get it in .20 .30 or .40 and the kit comes from grumpy preformence center out of oregon. Check them out and that kit and should i stay at .30 over or call them and tell them to go .40 i dont think they have started yet

Well i call the machine shop today and told them to just go ahead and bore it out .40 over. Much easier to find thoes pistons
