302 Break-in
The 302 that I have for the Comet was recently rebuilt. The guy I got the motor from had all the work done but never ran it and I have never gone through the break-in stage of an engine.
I have heard that I need to use 30W oil for 30min. at 3000 rpms.
Is that right???
Thanks for the help
