11 second smallblock...how would you build it?
I think a stock 318 with a custom Blow-through single turbo system is the best...no bottle to refill....easily tuneable via Boost Controller "Knob".
Cheap to replace.....probably run 11's all day, with or without slicks...and put wayyyyyyyyy more of a smile on your face when you nail it!
But like 1968FormulaS340 said....its quite complicated to do it under your limitations.
