How To Dial In The Timing On A Overhead Twin Cam Fiat Lampredi Engine

Here is the technique I used to dial in the camshaft timing on my 1977 Fiat 124 1800. This procedure may also work well for other overhead valve engines.

I did an on car variant of this and wish I marked the cam the way you did. There is this cool TDC tool I found that screws into the spark plug gasket and allows you to put your dial gauge in a better spot for engine TDC. I marked that so I can get the timing light on the exact TDC later. For the cams, you can look up the 110 number (some were 114, but 110 was common). I would recommend that you blue loctite all the adjustable cam bolts. Those should never back out. Looks good and congrats.

Great tutorial vid no bull . Love the twin cam engine sound. Thanks

Really important that the auxiliary shaft pulley is set properly. It can have internal interference if not causing damage to the engine.

Hey Chris, Thanks for your videos. I'm just embarking on a fiat Twin cam rebuild myself. Your videos have been really helpful. Can I ask where you get your parts for the engine?

Nice JOB! FIAT on,Cheers;)

Cool. Planning on rebuilding the carb? If not, you really should. Valve timing on is crucial, but so is proper fuel metering. Shame to do all this work and not the carb too.

I somehow forgot to include the carb footage in the video. Good catch.

very informative video! where did you purchase the degree cam gears? And what size cams are you using? Thanks!

[@ChrisClarkeFly]

I bought the gears from Autoricambi and I'm just running the factory cams.

great engine, i have a "Fiasa engine" (single over head cam) in a Fiat Premio, also an lampredi project, not too gold as the legendary twin cam, but good enought for a reliable cheap dayli.. Lampredi was terrible at his time.
