Does anybody now where I can buy a Duntov 30/30 cam and lifters from? I think there one of the best sounding cams and would like to put one in that 40 coupe we just picked up.
Lunati Camshaft makes a replica ... I have used them ... and they are good stuff ... http://www.holley.com/types/Chevrolet_SB_(1957-up)_Solid.asp #20109 part number ... sroll down the list and find it ...
SixCarb ! We have made that camshaft for 40+ years. It's sold under our Speed Pro brand, part number is CS-113R . The matching solid lifters are part number AT-992 which you need to order a quantity of 16. Any one that sells engine parts from Federal Mogul can order it for you.
Comp Cams makes a hydraulic version of it, part number 12-672-4. the N+30-30H cam. You can check their online catalog for it and the matching lifters. I haven't used that particular one but I've been happy with thir Exreme Energy series (XE-274=rumpity, rumpity).
For the Comp hydraulic 30-30 : advertised duration: 286 intake/293 exhaust, duration @ .050 : 239 /246 , lift : .483" /.477" , lobe center: 112 degrees. For the Comp cams solid lifter reproduction Duntov 30-30, P/N 12-673-4, specs are: advertised duration: 284 intake/291 exhaust, duration @ .050 : 247 /254 , lift : .504" / .498", lash: .012" lobe center: 112 degrees. Hope these stats are of help!
30 30 Millings part number for cam is c-10-p the lifters are part number JX 992 I hope this helps....bobby..
History question--gotta dig into the Chev library, but isn't this a conflation of two different early SB cams here?? The Duntov, GM # ending in "097", the cam's street name, was a circa 1957 mild hp cam designed by Duntov, using considerably less than 30-30 clearance...the "30-30" was a hotter cam associated with the hottest 283 vettes, about '60-61, the 30's being the unusually great clearance specified... Gotta go look this up.
Right. The actual "Duntov" cam was used from 1957-63, had slightly under .400 lift, and the lash settings were .012/.018. The "30-30" cam was used from 1964-69, and was borderline streetable unless you were running some stiff gearing.
the 12/18 cam was millings part no C 8 P..good for street less than 327 cid and sounded great with 3 inch stroke engines. I was told that all these cams were ground at millings and repackaged for GM sales. chev had high side specs and millings had the low side on spech for paper work.Years ago when installing in 55 model engines you needed to cut a oil grove as the 55 did not have groved cam bearings..Been over 35 years since doing this.
The 30-30 is the 365 and 375 horse 327 corvette cam. The 151 cam is the hydraulic 350 horse 327 cam. The 097 is the corvette cam from the late 50's. The 30-30 is a good cam but very dated by today's standards. You can buy similar spec cams that work far better for everyday street use.
On this note. Has anyone built a 350 plus horse 327 lately using new parts. I'd be interested in the specs on a recent proven 327 build. I have two I'm putting together.
has anybody ever used this preditor cam? good bad? Or know a better place to get a 30-30 with lifters. thanks in advance. http://cgi.ebay.com/NEW-SB-CHEVY-30...853?pt=LH_DefaultDomain_0&hash=item5195b6102d
Elgin also has a copy of the 30-30 as used from 64 to 67. I used their copy of the 57 to 63 097 "12/18" cam in my 57 FI BelAir-old design but sound good and work well with FI in my case BUT need compression for these cams to perform--also idle is around 850 for both cams listed above.
Now that there are some knowledgable cam people here, what was the Vette 350 350 cam, late 60's possibly early 70's, I put one in years ago and it doesn't seem to have it.
Thanks for the replies. I looked for Elgin and couldnt find any dealers. How about these? I did alot of searching and found the mellings part numbers for the 30-30 and searched it in autozone and found these, any input apretiated. I might start a new thread but when I do I know people are going to say use the search... http://www.autozone.com/autozone/pa...emIdentifier=179611_0_0_&oemPartNumber=AT-992 http://www.autozone.com/autozone/pa...0&fromString=search&isSearchByPartNumber=true
Joe: Got to agree on this one. It may have been the shiz back in the back, but cams have come a long way since. Unless you really need to have one, I'm certain there are better choices that will get you the sound you are looking for.
