400 big block + my 71 Demon

if you arent going for big power the schumacher headers are a great option. tti makes a 1 3/4 full length that works pretty good. they arent great for big power either though. i used them on 2 a bodies. they work with power steering. tight fit but it works. some guys have had some luck beating up a pair of b body hedmans to work with the b motor. a cheap option. there are some other options too. its a bolt in, off the shelf swap with what is available these days. go for a new truck stock mini starter right off the bat. dont mess around with those big old starters. too tight with the headers and just suck up the heat. with the b motor most intakes can fit under a flat hood with some kind of air cleaner. you can find plenty of useful info on bigblockdart.com
NICE! I am planning on "trying" the Summit $400 BB headers that I posted.. cheaper than either TTi or Sch. and come with 1 7/8" primaries - this isn't a balls out build - the motor runs (is/now was a derby back up motor) and the rotating assembly will be inspected and left if looks ok, just redo the top end to up the CR and add a nice Comp full cam kit

Already got the starter (stock style mini), my Demon has no power steering, no options at all so fitment "shouldn't" be to much trouble ("shouldn't" used loosely haha)
