| Post subject: | Timing and Break In? |
This thing seems to be running well. I started it and ran it till it warmed up this AM and then set the valves again. 18 in 20 out I also checked the timing with everything hooked up (didn't plug the vacuum) and it is running about 30 after. I run it until it warms up and I try to set it up at a high idle - I then let it run for 15 minutes or so and then shut it off for awhile. Is this gonna be okay for an "initial" break in - or??? Thanks, Dan |

What cam are you running? For a stock cam and many near-stock cams, 0.010" is where the intakes should be set.I started it and ran it till it warmed up this AM and then set the valves again. 18 in 20 out Quote: I also checked the timing with everything hooked up (didn't plug the vacuum) and it is running about 30 after.
Don't think so...the engine won't run at 30° after TDC. I think you mean 30° before TDC.Quote: I run it until it warms up and I try to set it up at a high idle - I then let it run for 15 minutes or so and then shut it off for awhile. Is this gonna be okay for an "initial" break in - or???
You want to avoid constant engine speeds and let it reach full operating temperature, so steady-high-idle and runs limited to 15 minutes (why?) aren't where it's at.

ISKY Cam - Grind #VA-160 - Part # 152116 Cam lift - .298 Valve Lift - .448 Dur - 264 050 Dur - 228 Lobe Center - 109 Valve Lash Hot - .018 I let it warm up to completely warm and then start figuring the time. I've also been reving it a little high - not excessively - and I high idle it and low idle it too. Guess I should have described that part a little better. Any ideas on what I should set the timing at? Thanks, D |

I have seen motors runat 30 after, not very well, but they ran. I suggest 10 BTDC as a beginning setting and work from there. |
