Trouble finding SBC cams.

I've been searching around on Summit and Jegs for small base circle cams, and I could only find 4 total, 3 on Summit and 1 at Jegs, solid rollers that is.

I want to find some SBC cams because I'm now considering building a 383 stroker and if I remember correctly, I would need to use a small base circle cam. Am I doing something wrong or are there very limited choices when it comes to SBC cams?

Also, is there any way to avoid using a SBC cam and using just a regular one when building a 383 stroker?

Thanks, Jeff.

Re: Trouble finding SBC cams.

Also, depending on the exact combo, you may not need it.
Mine, an internal balanced crank using profiled 6" capscrew rods, did not.

Re: Trouble finding SBC cams.

Ditto to what JimM said. I got into this issue and becaused I used profiled rods (compstar) cap screw type, I did not need a SBC cam but because I need a new cam anyway, I went that small route. I went with Ud Harolds grind recommendation in billet material. Lucky for me , I could still use my large base circle roller lifters. This issue also impact pushrod length.

Re: Trouble finding SBC cams.

I just called SCAT and they told me that they could work something out for a stoker kit where I would not need a SBC cam, but they said that (as you guys said) most cam companies will have no problem doing a .900 circle base.

Thanks again for the help guys. The maturity level on this site is amazing as well as the help that you guys give with any and all questions that I've had so far. Thanks again.

Re: Trouble finding SBC cams.

It mainly depends on your rods, if you use a "profiled" rod or a rod with capscrews you shouldn't need a small base circle. I have built quite a few 383's and I have never had to run a small base circle. The rods are what makes the difference. Stock style rods (nut and bolt caps) can cause more clearance issues from my experience. I used stock rods in my first stroker and still was able to use a standard base circle though the rods had to be massaged quite a bit.

Re: Trouble finding SBC cams.

Looking up parts on Jegs and Summit is easy and sometimes makes comparisons easy. But what you have to remember is they don't list EVERYTHING. A good trick at both houses is to find something you want at the manufacturers website, then go on summit/jegs and find their vendor prefix for whoevers stuff it is, then do a search for it using the vendor prefix and the vendor PN. And poof there it is usually.

Summit is easier cuz they use letters for the vendor prefix, Jegs uses #'s.

That probably won't work with a SBC cam though, you'd have to call Summit and they'd have to call Comp etc. But they can still do it.

Re: Trouble finding SBC cams.

Thanks for the great input guys. I think I'll go with the profiled Scat rods. Bob at Scat said it would be no problem using a regular cam with the profiled rods and they aren't very expensive at all.

Re: Trouble finding SBC cams.

Please contact Delta and tell them the spec's of the cam you want and to ask them for a quote for a SBC jobber using your furnished cam core.

I bet they can fix you right up worth the money IF the core will grind to this dia. and still be hard.

And I have a sneaking feeling that this CHEAP solid lifter cam from Summit is a SBC cam. Their PN 10341.

They call it a 264/246 108/108, 498" gross lift and it need's .030" lash on both sides, BUT I figure it is really this Elgin solid lifter cam.

E-1133-P; 280/246, 108/106, .498”, Lash, .030” and .030”.

Sucker was only like $45 plus S&H a while back!

A heck of a cheap solid lifter cam by me!
