the reason i have done this is to have more reliability as my car is a 23 year old xr3 and cvh engines are dated and usualy high milage, the 18 bottom end came out of a 66k escort which a mate owned but didnt put any anti freeze in and cracked the head, in my line of work this conversion is quite easy as i have got all the tools. so why not! IS THIS STIIL STRANGE!
