I was thinking earlier today...if I was going to do a 5.3 swap into my fbody, why not just go up to a 6.0? There is probably slightly higher costs involved with needing a bigger wastegate, blowoff valve, and turbo...is there a benefit from the 5.3 aside from being cheaper? The only thing I really need is the short block from either...
Thanks!
Thanks!

5.3s/4.8s are a cheaper (picked mine up for 150), have thicker cylinder walls, meetier pistons and can achieve a lower CR with untouched stock parts and are more plentyfull in the local jys

It all boils down to what you want. A 325ci 5.3L would be killer with good rods and pistons and a O-ring. Throw in a decent set of TFS heads and a 91mm Turbo. Good times for cheap.

same why I am building a 4.6 2v and not a 5.4 4v. Cost and you can still make plenty of power with a 5.3L. Thats the beauty about boost man. Makes up for displacement

I have no idea what any of that means lol but the weight is a big thing. I am doing an ALUM 4.6 instead od a IRON 5.4 b.c of weight. If you have boost just add 2 more psi and make up for the less cubes and still be lighter
