Can someone help break down the LSX motor for me? This may take a while however I have been interested in getting into all motor set ups. I am used to bolt ons, forced induction but never anything in regards to all motor and larger displacement. I was hoping someone could link me to, or break down for me what is what, how it works, why it is modified and what it will do and at what cost $$$.
For example... I hear these things, I know what most look like but...
Cams:
Pistons:
Top End:
Bottom End:
Bore:
Stroked:
Honed:
Crankshaft:
Head:
Short block:
Long block:
Aluminum vs. Iron vs. Cast bla bla bla
Rods:
Bearings:
etc... I notice people with there Fbodies, C5's, Goats etc with motors that are greater displacement than stock, 383's, 427's, 402's and so forth. What is the point of this? How will it benefit and what procedures take place? Also I was thinking, if a motor is upgraded to the best goodies, strongest components does it make it less likely to crap out? More likely to take a good beating? More reliable? Or does it simply lead to a less streetable more finicky car? For example I have always heard that the L88 Vette was not very streetable, it was a high strung motor that often would overheat in hot weather daily driving.

all motor meens that there is no power adder....most all motor setups consist of high compression longer duration high lift cams ...high flowing cylinder heads and all the needed intake and exhaust components....
this can be done with a stock short block or a new rotating assembly can be used...such as a forged balanced setup......
displacement well it just describes itself....more cubes is always better...hope that helps

I just know for forced induction compression often needs to be lowered. I am used to working with imports *cough*
okay really dont know what you want but ill try
Cams:there are so many variables normally more overlap means more power n/a in most cases....
Pistons:types forged hyperutetic and cast/styles dish flat top or dome
Top End:heads valvetrain camshaft ect
Bottom End:block rotating assembly
Bore:diameter of cylinders
Stroked:longer stroked or shorter crankshaft and rods
Honed:a fine finish after a cylinder is bored or done during an overhaul...
Crankshaft:part that pushes connecting rods up and down the cylinder
Head:cylinder head bolts to block allows air to enter and exit engine also seals cylinder to mmake compression
Short block:basicly an engine without heads bolted to it
Long block:a whole engine minus intake and exhaust manifolds
Aluminum vs. Iron vs. Cast bla bla bla cast is a process in which somthing metal is formed usualy compared to forged ...forged is stronger than cast..
in most cases an iron block is stronger than a aluminum..but aluminum is much lighter..
Rods:connecting rods conect crankshaft to piston
Bearings:bearings are like an insulate to keep the engine from wearing out....
and make everything rotate smoothly....
hope that helps like i said i really dont know what you want

What I am really looking for is a terms someone who doesnt know about this stuff can understand not defining terms I don't understand with terms I don't understand. More so, why do people change from this to that, what are the benefits of this or that, in what cases would you modify this or that and leave the other stuff alone etc.
Actually... what would a high hp, perfectly street able but track durable motor consist of and why would someone modify this or that.
Set up the perfect motor for street and track driving: From the ground up what would YOU use for parts and why would you use them. This way I will be able to put two and two together.

Cams:the camshaft is the brain of an engine...most of the time its changed for more horsepower...
Pistons:part of the engine that connects to the conecting rod...it moves up and down the cylinders to pull in and push out air..also to make compression..there are 4 strokes to our engines...#1. intake piston moves down to pull in air #2 compression the piston travels back up to make compression #3 power piston is forced back down from combustion and#4 exaust the piston travels back up to push out burned exhaust......
reasons for upgrading...for added compression to lower compression and mostly for added strength..
Top End:valvetrain components cam lifters valvesprings are changed for better stability when larger cams are used
Bottom End:a stronger rotating assembly is always better
Bore:
Stroked:stroking an engine leads to more cubes more cubes = more power
Honed:
Crankshaft:most upgrade to forged for added strength
Head:better flowing heads = more power
Short block:
Long block:
Aluminum vs. Iron vs. Cast bla bla bla
Rods:most upgrade to h beam rods for more strength
Bearings:
hope that helps

just look around the site and search...there really isnt a 5 minute course on engine building...

It does, I'm just trying to get educated so I can actually own an LSx car and know what the hell I am doing. I guess it would help if I had a better understanding of the limits of each component on these motors.
I am just very confused because I see people with say... a 402ci... and it is making less power than say an LS1 at stock displacement... it confuses me because why would someone want a bigger motor, only to have LESS power. This isn't even an LS1 + S/C I am talking about. I mean I will see a car for sale, with a 383 Stroker and it is not making that much HP compared to stock displacement... I can't imagine these things being very cheap to do so why. Makes this puzzle even harder to put together

If a stroker is making less than an LS1 something is wrong with the tune or the motor. Stroking a motor adds displacement, no replacement for displacement...the more air a motor can move in and out the more power it should make....
A properly build LS1 can make a lot of power, but a properly built stroker motor will/should make more power or at least more power down low.
There are a lot of variables though, including but not limited to compression ratio, heads, intake manifold, cam, exhaust etc etc....
