260 cam and igniting timing question.

So i put a 260 cam in my 22re and I am running 8 degrees right now. I am wondering what degrees of timing you guys are running and your valve lash specs? Thanks!!

It's been a few years since I built 22RE's. My son had a 260 cam and I had a 270 back when Engnbldr sold parts. I think the cams used stock valve lash of .008" intake and .012" exhaust. If not, use what the cam card says. I always like to set my valves at .007" and .011" to quiet them down a little. Ignition timing I always set to where it ran the best. Just a bit more advanced than stock. Just make sure there is no detonation.

This is just my way and I never had any trouble. Many more opinions out there.

Thanks for the input! On the spec sheet it said to set valve lash at 0.010” for both intake and exhaust. I think i set mine to 0.007 and 0.009, just going off what someone else used. You think I should change to 0.010”? And for timing im set at 8 but thinking of going to 10 or 12, seemed to like more advanced when I was messing with it when I was originally setting timing.

I would set lash as per the cam card. As far as timing, I always tried advancing it in increments and made sure it didn't detonate/ping. Especially here in AZ in the summer heat. What works for me, might not be good for others. You have to consider your use, climate and even elevation. Find out what works best for you. Without a dyno all you can do is see how it feels and runs for you the way you use it.

If it bucks when you start it, it's too advanced. Same if it pings/detonates under load. A few degrees over spec for me always started quick, idled smooth and at least felt like it had more pep. Even with a stock engine.

I also preferred NGK or Denso plugs, OEM cap and rotor and plug wires. NGK wires seemed to work well too. You'll notice the little stuff that makes a difference if you pay attention to it. I use a lot of Denso parts and avoid the cheap parts store stuff.

Good luck with your truck.

Ok sounds good maybe ill get the valve lash to 0.010 then and then mess with the timing, i feel like more advanced will help it out a bit more. Thanks!
