What do You guys think is the best for a low-boost application,a blow-trough setup or a draw-trough.

Building a truly cheap setup for my 27 ,using a AMC/Jeep 4.0 liter whith "the bad head" cast pistons in a otherwise stock block except for a small Crane cam 216/228 @ .005 and .484/512 lift. will not go that much over 7-8 psi of boost just to give it a chance to survive more than 10 minutes.

Turbo will be either a KKK K29 or a Holset HX 40 so it will probably be able to pump all the air I need and then some,I do have a Holset HX50 if the other ones end up being to small...
