How much should i expect to pay for one? Thinking of fitting one to the kitcar im building because of its simplicity compared to a zetec eg hardly any wiring ect as i want to keep the car as simply as possible.

also what kin of power will i get from one with twin carbs and head work just a basic figure please. been told you can get 150+ bhp with a bit of work.

Any advice would be great links ect.

Thanks.
