I have a 71 Cutlass with Olds 455. I am trying to fix all the issues to get her back on the road. I don't know what was previously done to the engine so I am looking for some help on were to start. I replaced the hei distributor, spark plugs, wires, vacuum hoses, and added a 650 holley carb. The car has Ga heads and edelbrock performer intake. I checked the vacuum and I am getting 10"hg of vacuum. I have checked for vacuum leaks and I have not found anything.


Were should I start looking next? What do you all suggest?
