Hey guys just in the process of breaking in my rebuilt 1968 327. Breaking in the cam today based on instructions from engine rebuilder, keep it at 2000-3000rpm’s for 15 minutes.

About 10 minutes in I noticed the engine was getting warm so shut it down.

I was running it with a stock fixed 19” fan, no shroud. I have a stock 64-66 V8 shroud but the 19” fan hits. Did these trucks come from the factory with an 18” fan?

Thanks.
