I'm now making plans to take my project to the next step...fuel injection and supercharging.  I was looking at ProCharger first, but the guys I'm working with think that a roots style blower would be more beneficial, as it would make boost more quickly, and they also think that with ProCharger, fender modification would be necessary.  Ew.

Anyway, now I'm looking at a "Gen 1 Classic" from MangaCharger...designed for small black carbureted and fuel-injected classic Chevy.

There's a link showing blueprints with height measurements from the top of the block.

I was looking to go with either Edelbrock's Performer RPM Pro-Flo EFI system, or Holley's Commander 950.  Now the deal is, I've currently got the standard small block hood.  I was considering going to the L88, but Ecklers apparently has the big block hood too, and that doesn't look bad at all. So now I'm wondering...how much additional clearance over the small block hood will the L88 hood give me, and then the big block hood as well?  Will I be able to fit the kind of system I'm going for underneath one or the other?  I want to avoid those ugly cowl hoods.  Gimme some suggestions, guys.
