Ok i have a few questions when it comes to engines, like when youre "port and polishing" your engine what does that mean and what are the pros/cons of it, same with engine balancing? i'm still learning lots about cars and this is something ive always wondered... so what do you guys know about those terms?... what exact does it mean when you get forged internals and such

 

ive wondered this stuff too, i was searching for forged internals for our cars after i saw this and i ran accross this.

Forged Rotating Assembly - $1995
Forged Steel Cobra Crankshaft
Manley H Beam Rods
Forged Pistons, .020 Oversize
Moly Rings
FM Main and Rod Bearings

i believe forged usually refers to the crankshaft and pistons, changing those out and putting something stronger in.. obviously i could be wrong so maybe someone with knowledge can spread some light on this.

 

I don't have much experience with car engines, but I've done a bit of work building engines for motocross and streetbikes that were raced a lot. So I may get things mixed up a bit, but i think they are generally the same concept.

Porting is done to the intake and exhaust ports on the head. A flow bench is used to measure the flow, and the builder cleans up and enlarges the ports to get more air/fuel in and out of the combustion chamber. better flow properties = more power.

Engine's come balanced from the factory to use factory parts. So when you start changing pistons, rods, crank, etc. you can start to throw things off. By getting the engine balanced you reduce vibration and stress and make the engine have to work less to turn the crank. this helps lengthen the life of the engine too.

Forged refers to how the parts were made. Forged parts are stronger than parts that were casted, so they can handle more HP.

There are a lot of great articles out there if you want a more in depth explanation.
