What Cam do I need and where do I get one?

I am running a 258 with Offenhauser intake and a Holley 390 carb with an upgraded ignition, I also have headers. I need a cam so I am not blowing fuel out the exhaust. What cam do I need and where do I get it? I am not to literate in figuring out the lift and all that. I appreciate any help ?

I would call a cam company like Crane, Comp Cams. and tell them your setup. they can suggest a cam that will be perfect for you. Wade

Re: What Cam do I need and where do I get one?

I am running a Crane torque cam I ordered from 4-Wheel Drive Hardware. It's the one with curve 1500-4500. Don't have the duration and lift numbers handy, but you'll see which one I am talking about. My engine is bored .060 over, and I am running the factory intake with a Holley 350 2-barrel, header, full exhaust, decked head, 3-way valve job and a few other goodies. The cam made a huge difference in performance, and the price was reasonable. I'd go with that!

I put a COMP cam and lifter kit in my 258 w/ mpi and the 4.0 head. It has 260 advertised duration w/0.447 lift. RPM range is form 1200 - 4400. It idels a little rough at 800 rpm, but once you get it up to its power range it is smoth.

Thanks Tippy

Do you think that iyou setup for cam needs would be equaled by the 4bbl carb and offey intake?

Re: What Cam do I need and where do I get one?

I called Competition Cams today and it rang and rang, tried the number again and the same thing. So I called Crane Cams the guy was great!!!!! He spent time with me and really helped me out. He reccomended Cam part # 753941 the specs were 484 Intake 512 Exhaust 112 Lobe seperation angle Duration 50 degrees 216 Intake and 228 Exhaust. I am also going to run a late model timing chain 89-99 to reduce the slop in the cam.

He also informed me that there is only 1 company that makes lifters now (never figured that). I was going to use roller rockers but can't find them.

By the way they were 129.00 versus 4wd.com's 139.00.

Re: What Cam do I need and where do I get one?

Does someone know the stock cam specs for a 258?

My 258 has an aftermarket cam (Wolverine brand), and I have the specs on that, I am just trying to compare that to stock to see if my idle problems are cam-caused.
Thanx.

You might want to talk to Clifford Performance in CA. They specalize in straight six's, and offer a few differant cam options depending on what you're running.
