Few questions for the Gen III experts. Sorry if these are rudimentary and covered elsewhere...:
- How much lift can the stock rockers handle?
- How much spring can the stock rockers handle?
- At what point do the stock rockers become unsuitable, a liability, and/or unstable?
- Can you sufficiently cam the engine to use the higher lift flow that is available and still use the stock rockers?
- Can the stock rockers handle .600+ lift?
- Stock rocker's are safe to .585" lift.
- I'd be more concerned about spring rate. Manley or PSI are my favorite 2 of valve spring choices.
- Spun the stock rocker's up to 8400 rpm. The main concern is harmonic's and premature wear to the rockershaft's.
- ??? Probably not.
-No, unless you buy custom valve springs.
Jerry Williams.

Does anyone know of an actual build, 5.7, 6.1 stroker with actual dyno numbers? A list of parts? What will work together? Cams and valve train parts? These engins are capeable of a ton of power, but a guy could spend a lot of money and have a bunch os mismatched parts. I'd like to build one, a stroker, carbureted on pump gas that would make 650-700 hp. It may not be possible though  .
It's possible, I saw a naturally aspirated 4100 lb. Charger streeter on slicks last week that has gone 10.70's in the 1/4.

got this on the net." now for the useful stuff.
Cylinder heads. big changes here, new closed chamber heads have smaller chambers (duh) than previous engines , 66.3cc in fact vs 84.9cc. even smaller than the 6.1's with 73.0cc. bolting these on to a previous hemi without modification would result in nearly a 12:1 compression ratio.
Are there pistons available to get a lower compression ratio than 12:1 using these heads on an earlier engine?I assume the stock later piston would work,not sure what CR is on late hemis though.
