doing much the same,got a 11" flywheel had it drilled etc,got a bell housing from salvage yard and.....can't get any dust shields to fit.The bell housing is not the full housing but the Chevy 1/2 or 3/4.Got a dust sheild today from Gm to go with the "292"and it fits the block but not the starter hole on the housing,don't know where to go from here.My serial # says the motor is from a G20 or G30 van.I also thought all housings were the same.Darn
