That’s a great point! Are there specific settings you recommend for the 30/30 cam?
For the Duntov 30/30, I usually set them at around .016-.018 for intake and .018-.020 for exhaust. This seems to work well for most setups.
I appreciate that info! What about the break-in procedure? Any advice?
Absolutely! After installation, make sure to break in the cam by running it at about 2000 RPM for the first 20 minutes, and then change your oil after that.
Thanks! Can I use regular oil for the break-in?
It’s better to use a break-in oil with additives. Regular oil might not provide the necessary protection during that critical period.

Good to know! I can’t wait to get started, but I’m a bit nervous about getting it right.
Don’t worry, tbrady! We’ve all been there. Just take it step by step and make sure to have a friend assist if you can. It makes it a lot more fun!
Or maybe just hire a professional? After all, sometimes it’s worth paying for peace of mind!
The Duntov 30/30 cam shaft is often lauded for its high RPM potential. It delivers significant performance gains, especially for street and strip setups. It’s important to pair it with the right carburetion and heads for max efficiency.

While the Duntov is great, I think it’s crucial to consider other options. For example, the Comp Cams Xtreme Energy line offers similar benefits with potentially smoother idle and better drivability.

Absolutely! Its 224/234 duration and .470 lift make it a solid choice if you’re looking for that performance swag. Just be aware of the necessary supporting mods.
Great point! The Xtreme series gives you a more modern profile. Has anyone tried it alongside the Duntov for comparison?

I’ve been using a Duntov 30/30 in my '69 Camaro for about two years. The lope is fantastic, but it definitely consumes fuel like a thirsty monster. Performance-wise though, it’s superb in the upper RPMs!

So true, @harrisjose! The experience with fuel consumption is a trade-off for that power. What about tuning? How tough has it been to get it dialed in?
I’m curious if anyone has had negative experiences with the Duntov. Every time I hear about it, it sounds perfect. What are the downsides?
Well, aside from fuel consumption, the Duntov can lead to a rough idle, which might not be ideal for daily drivers. It’s definitely a performance-oriented option.
The Duntov 30/30 is a classic, but I prefer an Isky cam for my builds. It offers a smoother power band while still giving impressive performance numbers. Has anyone compared them side-by-side?
Interesting perspective! I have yet to try an Isky cam. Any specific model you find particularly effective?

Using a Duntov cam definitely makes your engine sound like a beast! But let’s not forget the added wear on the valvetrain. Something to keep in mind for long-term use.
