Default Ever think of destroking?

Hey Ant,

You know, all this talk about strokers and big blocks can be a bit boring at times. What about a destroked small block? Say a 302 Dart or R block bored to 4.070", destroke to 2.90" (reduced piston speed and friction), zero balance rotating assembly, solid roller, Yates with 2.20" intakes ported to fill 301ci, and say a single 850cfm or webers. Very light, quick reving and spin it to 10,000 rpm. Sounds nuts but this could be a reasonably good endurance motor that makes a ton of power.

In a light car, not like a heavy JBL lead-sled dog, motors like these can have an advantage. Oh yes, you'll need some valve springs.

There are more options than just small & big block strokers. And, you could actually be different.
