H, I am thinking about getting a new camshaft for my 66 289, but I dont know that much about them other than that they will improve my torque and hp. I am looking at a used Lunati Camshaft with a lift of 235, and a duration of 285. I dont really know what those numbers MEAN, but if someone can tell me if this would be a a wise investment, and also how much it would cost to install something like this. thanks

More info would be needed to give a you a camshaft recomendation. Those numbers look a little off?
What is your engine combo and what do you want to do with it?

i would recommend installing a cam yourself, if u dont know how then get a book and learn. luckily my father taught me. as for the used lunati cam, thats a big NO. thats my opinion. for one id get a new one and for two, if its only a .235 lift then it wont be doing much more than ur stock cam. but if u change ur cam and nothing else ur asking for problems. u might as well change the intake as well to feed that big cam if u though one in there. i have a melling with a .448 and .472 lift i think. somewhere around there. not sure bout the duration. id recommend the edelbrock package though. its easier and works together. if ur gonna replace the cam u might as well just wait till u got everything and swap it out at once. the lift of the cam is how much it opens the valves (intake and exhaust) the bigger the lift the more ur taking in. i guess thats an easy way to explain it. hope this helps but im no expert, most every body else here knows way more than me but i just thought id try and help.

Those numbers can't be right. The only cam Lunati makes that has a duration of 285 is pn# 30602. It also has a grind number and exhaust lobe duration of 235. Maby this is what it is?

I would agree not to use a used cam. Unless it has very low miles, and I'm the one that pulled it, AND kept the lifters straight, I never re-use a cam. They are just too cheap to take a chance at doing serious damage to the engine by scrubbing a lobe.

First of all I would dump the idea of using any Lunati cam. I have had two of their cams that were improperly manufactured within the last year. The first one had the dist. gear cut too far to the rear of the shaft causing it to wear out the the gear on the distributor prematurely. Changed over to a Crane cam and no more problems. The second cam didn't have the dist. gear finished so the dist. wouldn't even go in. I'm still wrangling with Lunati over both of them. As for the specs it sounds like you have the duration spec at .050" lift(235*) and the advertised duration(285*). Even if the lift was .235" at the lifter it would only yeild .376" at the valve. I hope this helps you out,Scott

I agree....weren't they bought by Holley several years ago?. I have an older Lunati cam in my 69' and like it. Not sure about quality now that they are a subsidiary of HPP (Holley Performance Products).
