Too much engine work at once

This is the lunati:
  • Advertised Duration (Int/Exh): 256/262
  • Duration @ .050 (Int/Exh): 213/220
  • Gross Valve Lift (Int/Exh): .454/.475
  • LSA/ICL: 112/108
  • Valve Lash (Int/Exh): Hyd/Hyd
  • RPM Range: 1000-5500
Pretty mellow cam. The engine is a 69 with advertised comp in the day of 9.2:1.

So no, I know I cannot get it to fire right over like it was tuned already. When I did the new 4 barrel carb and intake it took about 10 seconds to fire and timing was off by 20 degrees or so. If it has to be key on and start and up to 2500 rpm in a few seconds, no way can I do that.


You can do it IF:

You are using a known ignition and you fill the carb bowls before starting. The key is to set the timing at 40 degrees BTDC on #1 cylinder. You do that by setting the crank at 40 degrees BTDC, dropping in the distributor, and lining up the rotor with number 1 on the cap. If you don't run a locked out distributor, you need to turn the rotor so you are opening up the advance and then line up the rotor with number 1 on the cap. If your timing curve doesn't come in before 2500 you need to use a bit more than 40 so you have enough timing on it so it starts and runs cool. Slow timing builds heat. A lot of guys try and set the timing at TDC and wonder why it gets hot and won't start.

The cam you posted is easy to make run.

If the engine turns over a few times and doesn't start...STOP and go back and verify fuel, spark, timing and compression. If it has those, it MUST run.
