I just purchased a 87 Iroc for $600, for everything but the motor (which was 5.7). First what should i go for a FI motor or Carb. second, i plan on having at least 375 horse power with at least TQ to match and was wondering if the tranny should be rebuilt or if the stocker can handle that much. Also would the rear end need an overhaul as well. Finally what gear(373, 411, 390 etc...) would work best w/ the 700R4. Any and all help would be extremely appreciated
