[DML] Questions Re: B280 / Chrysler 3.0 Intake Manifolds

["stainlessilusion" <5n-@xxxxxxx>]

I was told that all PRVs before the B280 have smaller intake ports
meaning the 3.0 has larger. By how much? I'm not sure. Seems that PRV
manifolds are very hard to come by! I'm in contact with numerous parts
dealers in the UK in hopes to find a B28A manifold, seems many of the
"European" version Volvos had carbs '80-'83 260s 262s 264s 265s etc.
instead of FI but so far no luck. Anyway-if the intake ports are
larger then the "O" ring,  I'm sure you could make hi-temp gasket
material work, you might need to grind a little away from the mating
surface of the intake but it will work. If these are as hard to come
by as the B28A intakes- I'm about ready to MAKE my own damn manifold!
