first those strokers using a windsor block over 427 are using the motorsport racing blocks not a stock block you can't bore the factory block that far.
Second issue someone asked if you could to that with a 429 umm well I suppose you could take a 460 crank, and destroke it a little to get 454 CID but to stroke a 429 all you need to do is change to a 460 crank, and pistons viola 460+ cid (or using aftermarket cranks upto 557 cid)
And lastly to those proporting that the 460 wieghs sssoooo much more than a 400 wrong. the listed weights are only 145lb difference to start with (less than most of you probably weigh as it is so go stand on your front bumper and see how much it really drops the front end) and secondly those listed weight differences are wrong, I don't know why they are published that way but from what I can tell the 400 published weight is for just the long block engine and the 460 weight is the long block engine plus ALL the accesories. actually go weigh a 460, and the difference ends up at around 30lbs then replace the factory iron intake with an alum intake and your at or lighter than a stock 400 with A LOT more torque. If you want to keep your 400, and try, and make some power with it more power to ya, but don't use falacies to justify you need to be different just admit you like to run something different than the other guy, and go from there.

 

If you want a monster, just pony up for the 514ci 'mountain motor' from FRPP. Im drooling on the keyboard just thinking about it....

 

Rich you could always build on yourself the FRPP is only a measly 612 hp why not go for something more in line with 800+hp<a href='http://www.smileycentral.com/?partner=ZSzeb008_ZNxmk705YYUS' target='_blank'><img src='http://smileys.smileycentral.com/cat/36/36_1_16.gif' alt='Evil' border=0></a>
