GEN IV 4.8s and 5.3s are all ironblocks. have you tried lifting a bare 5.3 ironblock? i can barely drag it lol but try lifting an aluminum block and i can lift it with ease

not true i have a 07 aluminum 5.3L Gen IV. it feels lighter than the iron 5.3L thats for sure was easy moving it on the engine stand.

ya, lots of 5.3L blocks are aluminum now, almost every one of them we tear into and are 07+ are aluminum.
haven't really paid attention to see if the 4.8L is alumin, think it's still iron, not sure though.

ya, i can bench press an aluminum 5.3L about 30times, and the iron block only 22times, much heavier

you talking 400 rwhp? or motor

Also aluminum 5.3 blocks came in trailblazers

Aluminum block needs sleeved to gain any bore size.
