Hi ScottyKilmer, im from south africa and i have 1976 ford cortina pick up like the size of a Chevy Alcameno. the engine in is a 1.6Litre kent crossflow engine, i recently came across an opportunity for 3L ford either a straight 6 or v6 to be put in but im not sure because of fuel consumption if it would be better to put it in or leave the 1600 Kent motor. Hope you can help?

leave it alone, modifying things is a pain in the ass

and if it would just fit in .... and i just wanted to know if the bigger engine was put in would it be more economic because the engine has to strain less to pull the body or with the 1600 kent?
