yes and no. a 302, no, a 302 stroked to something substantial, yes. my dad's 351 stroker made 487 bhp which would be around 410rw, and it's only 8.8-1 and has a baby cam and small heads...
I think a 347 with 11-1 compression and some good heads would make over 400 rw, but it wouldnt be 5k unless he found all the parts used.
Edit, I think Toby made 420 rw with a 347 as well... not sure on specifics.
