Surely someone with a '68-'71 has run into this....... When I first pulled the original engine out and had another built, there was no problem reusing the temp. sending unit on the early GM 487 heads that were on it. Second rebuild was with new aluminum heads. The hole in the heads was for a 3/8" sending unit and the original was a 1/2". I couldn't find a 3/8 sending unit that would register accurately so we put original in the thermostat housing neck. The engine ran hotter, 210 degrees no matter if it was 25* or 100* outside, unless I turned the a/c on then it would climb to 220*...... The question is...... can the Dart Iron Eagle head be safely bored out from 3/8" to 1/2" so the sending unit can be put back in the head where it belongs? It would look better, too.
