Re: Overheating issues
I just went and looked at the specs of the 350 gm ho crate motor . A couple things that I noticed . One was they recommend pump prem gas . What gas are you running . Looks like gm recommends a 93 prem octane . The other thing is they also recommend a total timing at 32 degrees total at 4000rpm , 5100 rpm max .
One thing that can contribute to overheating is a engine running to lean . If you are running a 87 octane gas this can cause it to run leaner . Also the 38 degree timing is to high in my opinion as well . This high timing can also cause high cylinder temps especially with 87 octane gas .
Just something to think about .
