I would think a entry level kit with little to no cutting would appeal to most. If they can design a kit to make a little 273 ci motor put out 275HP vs the stock 175 hp for around $2000 it would be a winner. Might even buy one myself.
What your looking for can be done very easily probably at 4500 4800 rpm and almost no lag 2000 rpm and up with a dual pane intake manifold and 600cfm carb
I agree No cutting is a plus and for a basic street kit I think that is possible, The down pipe routing is where im at with cutting the car a 2.5" - 3" downpipe can sneak out between the rear of the motor and the passenger side frame rail but anything bigger should dump through the fender well behind the passenger side tire and then back.
