How does stroking a block increase the stress on a block if the block isn't revved up more than it is accustomed ex. 350ci produces 350 at 4500rpm 383 produces 383 at 4500rpm, if the assuming 1 hp per ci, why would the 383 be putting more stress on the block if it is producing more power at a given rpm, and wouldn't actually work less than the 350 to produce 350 hp, i was wondering because people are saying stroking increases stress on the block.

I believe that the angle formed by the longer stroke puts more stress on the sidewall of the cylinder than with a stock bore/stroke combination. I've also heard that to help reduce this you should use 6 inch rods instead of 5.7's on a 383. I used 5.7's though because I found a set for cheap.

Getting there.....383 with Super Ram, Bosch 24# SVO's, MSD, Edelbrock 58 mm TB, 700R4 tranny, Eibach springs, Koni 12 way adjustable shocks and struts, and more!! Now let's pray it runs when it's all back together!!!!

 

So stroking causes more stress on the cylinder wall, are there any other problems with stroking, and does the longer your stroke mean the more stress
