well done on getting the car stripped

those heads certainly do look like 1.7's, the same set up as was on my old sprint

check the engine code stamped into the block, its on a smallish flat part of the block next to the dipstick hole. give it a good clean to see what you have. my sud (1.5) is an ar30146 and it has the different heads with the removable cam-covers. pretty sure yours is a 1.7, i guess that at some point in the last 21 years someone has put a 1.7 in for a bit of extra performance, think the 8v fits fairly easily without modification so would have been an easy enough upgrade

they obviously kept it quiet from the insurance though
