408 Scat Stroker Kits

I'm going with a stock stroke 3.580 for lower piston speed, and because I have 4.10 gearing. Otherwise, I'm pretty much doing the Scat cast crank thing.

Put a 4” stroker and 3.91 gears.

Your piston speed will lower because you make the same HP and TQ at lower RPM.

So what’s the percentage increase in piston speed from 3.58 to 4.00 stroke? How does that compare to a Chevy 350?

3.58 to 4.00 stroke difference is .42”; about 7/16”. But that is the total diameter is the circle the crank journal travels. The throw or radius of the rod journer only increases .21”; less than 1/4”.
