The pin height of a 383 piston is not the same as a 413 or 440 piston, so
the idea of putting a 383 piston into a raised block ( 413 - 440 ) engine
doesnt work. Yes you can bore the thing to gain the proper diameter ( a 383
and a 426 both are a stock 4.25 bore for example ) but the rest of the
equation wont work, the location of the piston pin in the piston is not the
same, and neither are the rod lengths or the strokes between a 383 and its
bigger brothers. Unless you want to cough up the dough for custom pistons or
rods, the choice is yours.
Dont blame me, Im just the messenger. Any good B/RB reference book, the
older Direct Connection - Mopar Performance stuff goes into this in depth.
413 pistons, for example, are rare yes, but not impossible to find.
Silvolite or Badger still offer them last time I looked, but dont get
suckered into using the later model truck pistons out of motorhomes unless a
compression ratio of about 7 1/2 to one turns you on.
Regarding brake bleeding....there are also some very very kewl brake
bleeders that you replace your stock bleeder screws with. They have a built
in check valve, so when you want to bleed the brakes you loosen one of these
bleeders at a time, and then you step on the pedal as usual without worrying
about having someone there to close the bleeder when you let up, as the
check valve takes care of it for you. When done, you just tighten the screw
as usual and move to the next wheel.
Im sorry that I dont recall the brand name, they are in Summit, Jegs, and
many other of the performance oriented stuff. Next to a pressure pot or a
mity vac, one of the best bleeding ideas around.
