I was thinking of running Comp Cams Solid "Nostalgia Plus" Seems like a good grind 247/254 @.050" 504/498 Tight Lash .012/.012 RPM Range 2300-6900 RPM
True; the old 097 grind and the Duntov .030/.030 are different cams. I ran the Duntov in my '57 years ago and the original 283 Power Pack engine loved it. I have a new Mellings replacement cam still in the box for the LT-1 350 I'm building to go in the '57 for this incarnation. I'll check the info card over the weekend to see what their specs are. But now that I think about it, I may have BOTH versions from Mellings. I think I may have ordered the 097 but changed my mind about putting it in a 350.
I use to run an Isky Revmaster in my 283's. Oh yeah, don't forget to FACE the tops of the rocker studs flat so the allen setscrew doesn't work loose on your locks. I liked the 2nd design Z-28 offroad stick.
hey BOOB...i ran a 30-30 cam in 64. c/gas 55 chevy. we had a 456 gear! believe me if U dont have a tall gear. the car will fall on its ass.the duration is around 275. comp. has some realy strong hydrolic cams. for street use. i would strongly advise comp. cams! call me POP...or the old FART!
we also left the 096 for 55 model year same as later made 097 but had a grove on the journal or race or whatever is the correct name closest to distributor. The cam bearing bearing was not groved in 55.. Lots of guys when installing this cam would cut part of the grill one or 2 small bars out so they could install the cam without removing the grill on a 55.. Plus it let everybody know you had a new cam...
Spec card on the box for my Melling 30/30 cam (their #22410) includes the following info: Cam Lift I .323 E .323 Valve Lift I .485 E .485 Duration (SAE) I 294 E 294 Duration (.050) I 254 E 254
[email protected] .485 lift 114LSA Made by Howards Cams "Rough idle, near duplicate of the famous Duntov 30-30 cam. GM #3849346." Upon looking at that cam I don't know why it would be sought after now a days
Took these specs from a Super Chevy article that was comparing the Duntov 30/30 (097) to the L-79 hydraulic camshaft. .485 lift and 254 duration @ .050. it was not a split pattern cam shaft. I don't think that the article gives the lobe separation or the valve event timing but here is a link to the article if you want to search out any more information: http://www.superchevy.com/how-to/en...-1003-classic-chevy-small-block-dyno-testing/
The factory 30-30 cam sold for 30.00 give or take small change at the Chev garage's parts counter here in town in the mid 60's. They usually had three n the shelf along with 3sets of gunned Corvette valve covers.
I've had a lot of fun with my 30/30 over the last 39 years...rev's out the wazoo ,adjust the valves about every 3000 mile...tach it UP! : IMG_3748 by bowie posted Aug 1, 2014 at 6:58 PM
MR48Chev is obviously an old timer. I was going to post the best thing about a 30-30 was the $30 price tag at your local Chevy dealer.
Duntov, 327, fueler, 30/30, popups, bored, stroked, stroker, camel humps, fuelie heads, fueler heads, vette, stinger, 3/4 race, full race, ported and polished, ported and relieved, oops that's flathead lingo, cammed up, balanced and blueprinted, built to the hilt. Somebody stop me!
Mutha thumpa, Bootlegger, Rattler ect...See, guys will STILL buy junk just cause the name sounds cool, some things never change...
Ran an 097 in my 57 Fuely-stock cam for this application--ran great--set valves at 12 and 18. Same cam used til 63 in Vettes-had one in a 62 340HP vette-a little less radical in a 327 but both ideled at 800-14" vacuum-both ran great.
They actually had them at the local auto parts in the town I went to high school in and they were still in the 30-35 dollar range in the later '60s. Or you could drive the 12 miles to the next town over and buy one from the chevy dealer. So while we are specing things out, I have access to an M/T 30/30. Anyone know the specs on that one?
I know I paid too much for my 3030, because it cost me 2000 dollars…….but the car came with it. It was, and still is, a 1965 factory injected Corvette coupe. In 1970, I took it to Teter Automotive in Elgin, Illinois, and we were able to pull 345HP at the rear wheels. With a 3:55 rear end and 2.20 1st gear, the car would do 70 in first at 7 grand. It would do 150 in 4th at redline, and did 12.42 at Great Lakes dragway with open headers and street tires. Still have the car.
In 1961 we built a 283" Chevy-powered Model T gas drag Roadster. My partner worked for an auto parts store and he got an appropriate Harmon & Collins(?) cam for our car. I didn't seem to cut the mustard so we switched to an "097" ($27?) and picked up a half a second. Maybe the old flathead cam profile wasn't what we needed.
Surprised nobody remembers when guys with the faster Chevs called the factory cams by color code ... "Orange code Duntov'', Pink code, etc. Maybe a green one, too. Must have happened in other parts of the county besides Idaho.
Hmmmmm I thought there was only one 30/30 cam. . . . And it was a solid lifter. Anything else is just a poser.
