Someone explain this to me.
 

Ok. Soon I am going to buy an engine for my swap. I think I want the 383. I would like to be a little different than the 350's that normally get dropped in. More cubes sound better to me.

I know that a 383 is a stroker engine. How exactly does it get more cubes with the same bore size? I haven't found a direct answer in my searches. If I go with the Vortec style fuel injected engine at http://www.desertperformance.com would I be able to pass emissions?

Also would the superram be a good match for this engine?

Longer stroke....the bore is the same, the stroke is how far up/down the piston travels, more piston travel means more cubic inches....many people go 350 because there is less stress on the block...people will argue...and overall a 383 is just as realiable, but any time you stroke a motor your stressing it more then it normally would be.

Well I don't plan on ragging the crap out of the thing. I don't street race to much and I don't plan on taking it to the track to much either. The biggest reason I am doing all this with this car is because I can. I enjoy the challenge of it.

A longer stroke also means that the diameter of the crank circle is larger. This gives the piston more leverage on the crank, hence the added low-end torque. 350's that are stroked to 383 need the block to be clearanced for the larger crank circle. Of course a 383 crate motor would already have this done.

I been wanting to stroke a 350 block i have also. Me and the guy that works with my dad have been talkin he says he think it wont last as long cause all the added stress.He was like i changed just the intake carb and cam on my mustang and it ran twice as hot and i switched from a 2 core radiator to a 3.
