how to know the difference between the vortec 5.3 and 6.0 and 6.2?
hey guys!
i have a toyota tundra 2008 regular cab
CAI, Headers, Straight exauhst, stall tourqe convertor ( something like that..changes gears faster) unichip, and a custom tune!
im racing the old silverado.. he said its 5.3 cai headers and a tune..
were gonna open each others engine look for nos and other mods..
so how would i know if he's engine is the 5.3 or the 6.0?
if not from the engine cover then were else?
type vortec 6.2 in your search box, and click on the link to wikepedia this will discuss some of the many different engines gm has, as to picking out one engine versus another, this is going to come from experience more than anything, off hand, having been around engines for many years, They have various differences, which after awhile you notice, You either need to spend some time looking at, or working on a particular engine, one basic thing is size, the 5.3 is smaller than the 6.0 or the 6.2 I grew up knowing the 5.3 as a 327 chevy this is a smallblock chevy that was could put out an impressive amount of power for its size, a 5.7 looks similar in size, and will beat it off the line, the 327 made all its power when it started revving hard, off the line a 350 could smoke it but once you got up around a 100 a 327 started putting down some power and would outrun almost any small block on top end.
Just from reading online, and my knowledge of engines, the 6.0 is physically bigger, and will be similar in size to the 6.2 what I read online is the 6.2 is an all aluminum cadillac motor, that would stand out right there, all aluminum, means the block and everything, so find a cadillac escalade with the 6.2 in it and open the hood and stare at it for a while, look it over, take your time, your eyes, and your mind, are what you are going to have to get the overall impression of, and one way to do this is either spend time working on the particular engine you want to know about (like getting a job in a shop or dealership, or finding pictures online (this may help) but you physically inspecting and looking over each engine, is the best way to wrap your head around what you are asking,
I can tell from the question, that you like cars, but you have not spent much time under the hood or looking at individual parts, because for example a torque converter is actually on the front of the transmission, and Im guessing you meant you have a stall converter that is not stock,
If that truck has a 5.3 (or 327 ci) it will look kinda small in the engine bay 6.0 would be larger 6.2 all aluminum cadillac motor would be easy to spot. Not knowing who or what put the silverado together, I cant tell you what they did to it, I can tell you that if its not stock, and has been built by someone who knows that particular engine, its going to be not so fast off the line, but when its start to rev the longer it does that, the more power its going to make and its going to get moving in a hurry, especially on top end.
When you guys are racing, you need to do a lot more reading and try to understand things like power to weight ratio (and there is actually a math formula that can explain this) because the heavier a truck is, the harder it is to get moving, and the harder an engine has to work to get it up to speed.
I never raced a toyota pick up, there were none around when I was racing. all vehicles have strengths and weaknesses, some truck engines have more bottom end torque off the line, and will put power down up to a specific rpm and kind of bleed off power, others like that small block 327 is going to fly by you up above 100, if its set up right, you will think your truck broke, so if your truck is fast from 0 to 100 then you better not go over 100 or some guy in a 327 is going to clean out your wallet. ( I don't suggest you race on the street, this is a fantastic way to end up in front of a judge, or wrapped around a tree, because some eggplant in his moms car pulls out in front of you at high speed) if you are smart, you will do all your racing on the strip at some local drag race. Because you can lose your car, your license and your life easy.
Things like fuel injection versus carb make a difference in hp so does air pressure, I loved winter, because ice cold air is denser (again there are math theories that explain this) and it makes more horsepower so any high performance engine will make more power on cold mornings. things like that.
The big thing in racing now, is computers, if you want to get involved in racing, start learning computers, and find an area that needs improvement and figure out a way to make it better, and you will end up at the top of the game. It takes practice and patience to learn anything, your cars engine can run different each time you race, you have to get used to exactly how to get the best rpm and keep it going down the track
