turbo: blow thru vs. draw thru

I may throw some ported heads on the motor with a new intake first.... With your experience, is it hard to run a double pumper/mechanical secondary carb with this setup? I plan on running a loose converter...

Usually not an issue, as long as you can handle the jetting for a richer top end. The progressive carbs make that easy to do. Obviously you could run 12:1 A/F all the time, but that sucks fuel... I ran a Predator carb on draw through just fine.
