Manifold question

I doubt I'll ever see 5k RPM with this engine/car.
I didn't think the 260 I'm considering, was 250*@ 50. I'll have to check that. (mostly considering that 260, just because it's here/ I don't have to buy it) along with the Performer and Offy intakes I asked about.
but nevermind that, for a minute. still looking at "where would be a good application to use the Offy that I have"/ partly as a "do I keep it, do I hang onto it for future" or do I sell/trade it away? kind of thing.
