340 camshaft break-in. Well.....almost

  • I start with the idle adjustment turned up, so it would idle around 1800-2000 rpm's. Keep in mind, this doesn't have to go "flawless". I've had things force me to shut them down early, restart and continue. I've had cars not start right away due to no spark. None of which caused any issues. Valve spring pressure plays a part.
  • you wouldn't watch the "lifter rotate". Take a paint marker and put a line up top the push rod by the rocker. But don't bother unless you have suspicion of a flat lobe.
Thanks that's a good idea with the idle I was kinda thinking that but I didnt want to say something and sound stupid lol I wasnt sure if it would hurt something turning one up that much.
I think I solved my carb situation. I have been really worried about rebuilding my own and running it on the breakin. So I have been talking to Dana on here and he/she is gonna build me a thermoquad. He rebuilds the cores for 155 (fabo discount) and charges 50 for the core. And he guarantees it to run he tests them out and sets it up on his engine. I may have to make adjustments and tune it to my engine but he said it will start and run for the break in. Plus it will give me the factory original look I'm seeking. And I wont have to run a stupid spacer on my spread bore 340 intake. It's a win win win for 205 bucks!! I will keep my carb and rebuild it just to learn on and practice with and after break in even see if it runs lol .
