I heard a friend say something about a stroked motor will blow cleaner for emmissions. Like say with my cam ( in my sig ) and a 382 stroker would my car blow cleaner?

 

the longer the stroke the more cam you will need. IE a 346 will pass CA smog with a 224/224 lsa 114 but not with a 228/228 lsa 114 but a 383 with a 228/228 lsa 114. would pass ca smog. the more stroke you go the bigger cam you can get.

 

Thats true for the most part. A stroker motor will not burn cleaner than any other engine just because it's a stroker. The cam and tuning will effect the emmisions. As said, a stroker motor will "use more" of the cam, and thus burn cleaner than a smaller displacement engine with the same cam.

 

Yep, more displacement can "suck up" more camshaft. So with the same cam would have a better chance of passing in a higher displacement motor..

 

sweet guys thanks for the info...i just recently found out that my motor isnt doing to good right now, so im looking at some options while its out of the car

 

Curious...
Since on this topic...
Stroker with a stock LS1 cam? Obviously the power will be down a good chunk, but what about passing emissions? Should do it easily? Or not enough cam to even run proper?
