A 440 A-Body... that can handle?

ok. i had to chime in on this one. i have two perfect comparisons in my shop right now. my duster with a 380hp crate 360 and a 5 spd,AND jon clarks flat basterd valiant. our car are set up the same with RMS suspension/brakes/wieght/ blah blah. flat basterd has an ALL aluminum 528 wedge,efi,6 spd that is almost 700 horse. i raced this car at the PHR Musclecar of the YEAR last summer. of course i race the dammit out of my little duster at autox/roadtrack events. having driven both hard. i could not imagine an iron block BB in one. not to mention the fact that it is a bee-hotch to work on,it is just too much wieght on the front. 700 hp is alot to control on an auto-x,but on a road track it would be nice. i am a SB guy and sure do not have the cash for a Ray Barton aluminum motor,but i just think it is too much. it is a blast to drive though! if my 360 goes,i will punch it to 408 with aluminum heads,have my 500 or hp and go racing. oh,and be able to work on it.
