427 is a lot to ask of an OE block.
The biggest I would go on a OE block would be 408. In my experience the 392 is the best stroker combo for those motors1971 Camaro, 383 stroker ~500HP,M21 Trans with lightened flywheel. All Sorts of Auto-x Goodness in the Suspension. 12" Brakes ->SOLD
But ask me about my 2004 STi Auto-x car...

Well that is not exactly true... when you start getting into strokes over 4" one really has to clearance the hell out of the block, which weakens it, which means you have to fill it, which means that you have to be VERY careful with the cooling system so on and so forth.
Just because the magazines say its easy dosen't make it so.
Stay away from Hyperutenic pistons in general; they are brittle.
What kind of budget do you have here?1971 Camaro, 383 stroker ~500HP,M21 Trans with lightened flywheel. All Sorts of Auto-x Goodness in the Suspension. 12" Brakes ->SOLD

I raced and drove it for 2 years.
you do need to limit the bore to 4.030 no .040 over stuff and you need a good aluminum radiator with a good fan. no black magic BS fan. i run a OEM fan from a 3.8l taurus.
try visiting www.hardcore50.com for some real ford engine tech.
i do not know know if you can stuff a 427 into a stock block though???
i am now building a 4.125 bore 438w in a dart block. can you say low 8's and 1000+ HP????Chris V
