Does the 5.3 weigh less that a 4.3 V6, here's why I ask

I lowered my truck after the swap, I thought after the swap with the stock suspension on it that it sat higher in the front that it did with the 4.3 in it but I thought that may have been where it had been on jackstands and off the ground.

Friend and I put on a 4/6 kit and the truck does not sit like the other OBS trucks I have been around in the past, it sits level with no rake

If it's an aluminum 5.3, yes. I believe the iron blocks are still about 30 pounds heavier. My truck sits the exact same as it did when it was a V6
