Guest Posted June 12, 2003 Share Posted June 12, 2003 Hey guys, do any of you know what the stock Horsepower rating is for a 1986 Olds Cutlas Supreme with a V8, 5.0, 307 is? It's all stock, just wondering what the stock HP rating is. Thanks Link to comment Share on other sites More sharing options...
rocketraider Posted June 12, 2003 Share Posted June 12, 2003 140.Interesting to note that the 80s 307s made about the same power as the original 303 Rocket. The 303 was the hottest thing on the road in its day. The 307 was considered anemic. Times turn around... Link to comment Share on other sites More sharing options...
