im just wondering if anyone has an idea of how much a naturally aspirated 5.3 is capable of on the street with pump gas. NO NITROUS, NO BLOWER, NO TURBO. ALL MOTOR. just wondering for conversation. and what was done to it to get it to perform that well ?

 

Id say 420.

 

look for skeet...hes the 5.3 man

 

Skeet has a 6.0.

 

oh yeah it was someone else...wtf i was thinking...my bad

 

400ish

 

Never seen one over 400rwhp

 

I would think 400rwhp out of a stock shortblock 5.3 would be pretty damn hard to achieve.. I think 380-400rwhp would be realistic..

 

Not on pump gas anyway..

 

well then........sounds like a good project to play with just to see what can be made. now the hard part...finding the money to get a vehicle and getting it done lolol
