Which is why I'd always recommend a 3400 Top Swap since the head pattern is correct.

I'm sure a Milzy Cam, 3400 P&P'd Heads, P&P 3400 Intake Manifold, Larger TB, and headers...should net you at least 200 WHP...which would make a decent 14 second daily driver...but don't expect your HP per $ figure to be worth a crap.

I agree but wouldnt starting with a 3400 block be better since the pistons are larger and putting p&p'd 3400 heads and 3500 intake plenum make for a better n/a car,
But starting with a 3100 block and a 3400 topswap(what you said) sounds like a good turbo setup, and milzy gots a turbo cam setup that ive read good things about. what do you think?

This totally depends...is the compression ratio the same?

I'd swap over the 3400 top end if the compression was higher on the 3100, if not...then yeah I'd agree to just toss in an entire 3400...but I wouldn't do that without going through it...that's for sure...heads/cam/P&P'd top end...etc.
