Is anyone running a 3.185 stroke crank or any de-stroked crank? Could I you tell me your setup and the numbers that you're pulling. I'm looking at running a road racer and this seems to be the right choice.

 

Why does this seem to be the right choice?

 

Because IIRC that is the stroke of the ALMS C6R's.

 

The only application where destroking an engine is applicable is in class racing that restricts cubic inches. Other than that it is an unnecessary waste of money.

 

how? a high revving engine that lives up top (way up top) is perfect for road racing. why do you think the chevy 302 did so well? also, from the sound of it, he is racing in a CID restricted class of 305 simply because the 3.898 bore and a 3.185 stroke is just under 305 cubes.

 

Unless your rules require the engine be under a certain limit I would build a bigger engine. The 3.185 was required by rules for Daytona Prototype in the early days, they would produce around 490-510 in legal trim which had a 6500rpm limit and valve lift limits.
