I looked through all those sites and I liked http://www.chevymania.com/tech/383.htm the best. It's really straight forward. Now I actually know something about 383 Strokers.

Grumpy, can you explain this?:

A basic short rod 383 will live to 5500 and a 5.7" rod motor will go to 6500.

I don't understand. How does the rod length affect the red line?

theres several factors,the rod ratio to intake efficiency and volumetric efficiency ,the rod to stroke ratio,the rod bolt strength, the effective load angles, and the max piston accelleration curves on the piston and rods. while I doubt the true effective differance would be that great GIVEN exactly the same strength rods due solely to rod length alone the stock 400 chevy 5.5 rods are weaker on average than the 5.7" rods in a 350 and the aftermarket rods are significantly stronger than either one. but if you read closely youll also find that the shorter the rods and the longer the stroke the lower the rpm levels where the engine tends to reach max efficiency at filling the cylinders, now max torques is almost always very close to that same rpm level and as the engine looses the ability to effectively fill the cylinders power falls off rapidly
