Steve, the first problem you encounter is that the '80 spirit is not in the classification guide. ... That problem is easily rectified by converting the car to a '79 model. ... Now you have a car that is in the guide. Your choices are the 258 six or the 304 V8. ... The 258 is the better choice. This combo is very similar to the one I built for Ed Fernandez's current T/SA record holding 77 Gremlin. .... The 304 combo is only 15 hp more , but the 304 is 2 lbs higher in classification. If you want to persue the 258 ,start by checking the casting #'s in the guide against the ones on your nephew's Spirit . ..They may be the same as the '79..... If you want more info on this combo contact me on the PM link. ... Tom
