First time Aluminum block questions - 07/16/23 03:36 PM
Hello all. I am building my first aluminum block big block engine. I have built iron block engines with aluminum heads in the past. I have always ran the iron blocks on the run stand up to operating temp. Then I allow the engine to cool over night and retorque the heads. What I don't know is this. Are there any considerations like this for the aluminum block? Like do I need to retorque the mains? Any first fire up tips pre and post would be greatly appreciated. Thank you, Digger73 (Mike)
