well if you building a hi rpm engine i like the 6.385 rod this helps in two ways one is it can go internal but thats not a very big deal but if you thinking buying new rods and forged pistons and forged crank then i go 250 longer. i used the cast steel cranks and forged steel as well that are cut for the 6.135 rods. but the cast steel cranks and hyper pistons for lower $builds i use the gm truck /rod thumb rods or the scat I beams work good to but the cost is same for the 6.385 s .i do not deck the block till pistons are in hand like i said some of the forged pistons are not always the same CH . but like i told you. buy your pistons for a 489/496 if you building 030 to 060 over with the 4.250 crank and the 6.135 rod . in custom pistons you can get the deck were you want but with a 1.54 not every shelf piston many not give you a O deck if you deck the engine to lets say 9.780 so i look the piston up first before it gets deck. if you know the piston CH it is EZ math . then i deck the block to what ever i want
