If you've been following my top end rebuild thread you know the 454 in my K3500 is ruined from neglect. I've been thinking about what I'm gonna do about it, and I think stroking it is the answer. The truck is gonna be a mud bogger, so I need as much torque as I can get. I've already got the heads reworked, and from what I can tell they'll flow plenty good enough. It also seems the Vortec intake and injectors flow good enough with a tune. There's a wide array of stroker kits available for this motor, and I'm not sure which one to get. Based on bits and pieces I've put together, a cast crank with forged pistons is sufficient. Flat top pistons should yield ~9:1 compression which will be fine on pump gas. However, some kits have a balanced crank and some don't. Will there be problems using a balanced crank in an externally balanced engine? Also, the coolant passages around the cylinders were packed solid with rust, so do you guys think it's still safe to bore .060 over?
I'm planning to go with suggestions from Comp Cams for the top end. They recommended #11-235-3 for the stock rotating assembly. Haven't gone back for a new recommendation yet.
