The most proven all-around performance "package" for a 346 is the AFR 205s along with the AFR 224/228 .581/.588 114LSA (+1) cam. This package will make power both low and high and has good street manners. A more aggressive combination would be AFR 205s with a Thunder Racing TRak cam or an LG Motorsports G5X-3 cam. Both are proven to put out big numbers.

I did back to back testing of the AFR small bore 225s vs the AFR 205s with a TRak cam, FAST 90/90. I only gained 5rwhp/5rwtq, but in the process lost quite a bit of street manners and fuel economy. Not a good trade off in my view. The 205s made 487 rwhp in race form. That should be enough to satisfy most individuals.
