i'll give u the numbers in about a day so i'll have info looking for the original engine for my 66 skylark 2 dr hrdtp. it dosen't have the same engine in.. they did not make a 350 in 66 for the skylark... looking for what came in these stock
The 350 was first put in the 68 and carried through to 80, so there is no 350 motor that would seem stock.
Stock V8 was 300 cubic inch with a 2bbl carb. Optional was a 340 with 4bbl. If you have the original warrenty booklet, the protecto-plate would have the engine code stamped on it.
