B or RB in A body

what year is your A body? earlier cars (up to 66 or 67?) had a narrower distance between the frame rails. i've put a 440 in a 65 dart and headers were a nightmare to make, even the fenderwells that i did. the 383 i'm putting in my 68 valiant now is much roomier, wider engine bay and smaller motor. with the schumacker headers i still have factory power steering and will keep the a/c although with a modern sanden compressor :thumbsup:
stroker kits can get me to as much as 496 cu in so that along with the fact that a 383 is cheap compared to a 440 and it's smaller made it a no brainer for me.
neil.
