232 crank vs 258 crank | race stroked motor

[Nick675]

I am entertaining the idea of using the 232 crankshaft with 3.500" stroke vs the 258 crankshaft with 3.895" stroke in my stroker because 1. I am building a race motor that will need fast response and 2. the engine will have turbos so I am not worried about making a big displacement motor.

I also have not decided whether I will use 4.0 (6.125"), 4.2 (5.875") or Eagle rods (6.150"). I'd like the Eagle rods for strength with boosting, but not sure I want the long rods.

I will be using forged pistons with 26-32 cc dish and possibly O ring block and head

I am basically writing this here to entertain ideas and thoughts from fellow experts

Hey,
Either long or short stroke should work well, but the forged pistons would be a good idea with a turbo. I have the KB 945's and I may do a rear-mount turbo at some point. The turbo will allow for the basic build to be moderate and it should make good power anyway.

Oh yeah, the Eagle rods would be nice. Mine is the long stroke version and it revs PLENTY quick.

Why would you stroke it if youre not worried with more displacement?

You will be limited by the amount of boost you can run if you stay with stock rods.
