Don't have 8 of the flat top pistons. I have 7 because the l33 threw a rod and the piston and the block broke. So if I use it, what does imbalances do? I'm guessing it will shake and break the new stuff? Guess I will go look for a piston.
Yeah you need to get a set of drop in pistons if the block didn't get bored and if the block is still good. The machine shop checked the crank but not the rods right? Did you measure any of the rods to see off they were off? I made it home to Aransas Pass I didn't think you were going to be tightening bolts so soon. What damage did it do elsewhere such as the head and bore?
No damage to nothing else when I broke the piston, bore is good. I had my hand under to I caught it. I did find 2 pistons that's dish from a 05. I got 2 because they traded the flat tops for these 2. The pic with the weight 44.20 ounces is a piston from the lm7 just a different cylinder. I weighed the two new ones and took pics and the with is pretty close, the inky difference is the rods are pressed on the two new ones and the 7 from the lm7 is not and has snap rings. Will it be ok to use one of the new ones. Unfortunately buying a set of drop ins is not possible due to funds are an issue. I took pics of weights, tops and rod connectors. Which one will work the best? Piston from other cylinder.

Hey there man I made it back to Corpus had to go into the hospital apologize that I couldn't come give it a look. Too bad you don't have a 4.000 bore I have a whole set of rods and Pistons with 100k on them but in great shape

You need to use the same type piston. You can not swap them. One is a pressed type pin and one is a floating pin with clips tor retain it. Running 1 different piston and rod combo will throw the compression ratio and the balance off.
If you are using the L33 rotating assembly, Stick with the flat top piston. You can buy a used one if money is tight. The block won't know the difference.
Well I put the motor in and it's running. Just have a few issues like on broke break line and an exaust leak. But for some reason nothing inside is working. The dash turns on but gauges won't work, windows don't roll smdown, ac button won't work, 4wd buttons do t work. Only thing that works is blinkers, blower dial, rpm gauge and radio will turn on but no sound. Kinda stumped on the electrical stuff. Imma do the brakes this week and the exhaust leak. Thank you all for the advise and when it started I was extremely happy to get my late brothers truck running and successfully built my first motor.
