which one can hold up better 5.3 or 6.0 n2o?n how can they handle

 

Both are great and will haul @ss with a shot either way, neither is really any stronger than the other as far as "strength". So obviously given equal circumstances Bigger is Better

 

whats the most can a 5.3 handle?

 

I saw one take 250 shot of nos and is capable of another 25

 

oh ok thanks...but tell what u think,of this step up,pls....125 shot,ls6 rocks n harden p/rs ls6 springs,lts n stright pipe,tr220 cam n lifters,intake n 90mm (will the fast intake fit on a stock 5.3?

 

125 shot....fine but could go 150 safely
springs...fine
Lt's....great
Straight pipe....dunno bout that one
Tr220...proven time and again, but kinda soft to me down low personally on 5.3
90mm intake....fine but your stock manifold will go a long way and that money could be spent in several other key areas needed friend. FAST will work but would be overkill in my opinion for a stock headed small cammed 5.3

 

whats wrong with stright pipes?i know it kills power i like the sound but what u suggest on the cam n intake part?i can find any other intake no where.....n oh yeah forgot the tune for either wheatley or nelson
