I want to get started restoring my 73 GT. I'm just not excited about the original engine. I want to do a engine swap but I'm just can't decide what to put in it. I have a T5-trans. I thought of a Quad 4 or a Ecotec. Is there information on these swaps or others? No V-8s please. I think the V8 is way too heavy for the car. I'm a road racer and would like to be able to take the car out for some laps. I'll be updating the axles and brakes too. I love the styling of the car just no its mechanics.
