I did one back in '98 with a Goodwrench 350. Paying close attention to the quench, via FelPro's 1010 rubber coated gasket, a set of 195cc TFS aluminum with cnc'd chambers, a Comp Cams XE series camshaft topped off with a Performer RPM Airgap and a Holley HP series 750... it netted 438hp on 87.
Then... CHP did a very similar build in Feburary 2001. 411hp on 87... with ease. With pretty much the same parts. Hummmmm
Now if I could find a link to the actual article....
This is part of the series that stemmed from the Feb 2001 build. It was a cheaper build with different parts yet still netted 390/425. Change a part or three... and you could have 425+ hp and still keep it on the cheap.
