Why didn't you buy a 6.2? That's definitely the easiest way.

if you want crank, which is all your gunna get out of a 5.3 unless you blow it or spray, p&p heads, balance and blueprint block and crank, big cam, usual stuff.

i guess so then huh

if you want "flywheel hp" you can do a cam/ud crank pulley/tune/LTs/OR-y/Exhaust/CAI and make 330-340rwhp which times that by 25% is 412-420 flywheel hp

so either you want rwhp or flywheel hp....

understood but when someone says "400hp out of a 5.3" is a lot harder to do vs being on Nitrous, Supercharger, Turbo. ive never seen a N/A 5.3 make 400 rwhp but then again i dont know crap so


if i had to do it over, id do a front mount turbo, with a spec'd cam
6k in my swap including all the mods and tuning vs 6k for front mount thats gonna make 500+hp
