who has used it or still useing it? and how do they run on the street. I am thinking of putting one in my 327 for my a sedan.
I'm pretty sure that's what's in my car. Motor's been in it since 1965. It's runs good and sounds even better! It's sounds like a drill, whizz whizz. I'm running a 4 speed, and no vacum advance, it might be tough to run with an automatic. A word of warning though, it's hard not to get on it at every chance I get!!
I ran one 35 years ago in my 55 w/283 punched to 292 w/stick turned 8-9 rpm all the time. Nice responce fair idle. Dont think it would have worked w/auto w/stock converter.
valves are real loose on the 30 30 that means 30 thousands , thats loose needs lot of attention , i used to run one in 56 chevy , it would run like u terpintined a cat
I've ran several of them over the years. They do have an impressive idle, but I found them pretty soft below 3500 rpm. It will wind out big time, but you have to have your rpms up to get the real performance. I thought the earlier F.I. cam for the 283 was a better street cam, the 8 and 18 Duntov.
i did monthy tuneups on a corvette for one of the younger engineers at the a/c sheet metal shop next door to where i was a mechanix ...you must make sure you have it on the flat of the lobe to set it then you will get a true 30/30 setting not too noisy then &setting lasts longer
30/30 with solid lifters, good breathing and exhaust via a stick trans/ good rear gears and you will have fun on street/ some strip. Check cam builder sites for specific info. More than one supplier now. I had a all stock '54 Ford 1/2 ton PU with a true Vette small block with the 30/30 solid lifter set up. I would pull up to a stop sign and would see people looking around for the Corvette that the sounds were coming from. It was a lot of fun.
Have run several "30-30" cams, and have had great luck running them at .028/.028 - the lumpy idle can't be beat and while they don't have the pull at low rpms, when they come on...it's just exciting. My enamoration with adjusting valves interminably has subsided over the years, and pretty much I either use the LT-1 (370hp) cam or a good quality aftermarket with similar specs for a hydraulic dual-purpose cam that still elicits a nice rumble at idle. dj
Great cam for street and strip. I ran one years ago in a 327 with fuelly heads and a tricked powerglide.It would run hard all thr way to 7500 rpm with a stock points dizzy.And you will never get sick of that idle.If you want to sell it I want first dibs.
Back in the late fifties and sixties it was about the best cam you could buy for a small block chevy , we always ran them in 283s and 327s , ,,,,,,,
Crane cams makes one, I belive it's in Something like "Factory Muscle" cams or something you can get 'em through summit, they call them a stock 64 vette solid grind or something like that, it's the one with .485/.485 lift Was gunna run one on my 301 in my 64 'camino but i think i'm gunna try the "Factory offroad 1" also known as "041" z-28 grind instead
i found one in the competition products catalog made by elgin for 169.95 with howards edm lifters. for the rest of the motor i am thinking fo going with some aftermarket headsbecause it will be more cost effective than having my 461s rebuild. and i have a offy 2x4 intake with 2 afbs. i am hoping for around 425 hp.
Aftermarkets just dont look as cool as camel humps, i wish i could run em' on my 301 but i'd be over 11 to 1 with em
I don't believe you can run a 10.5 motor and probably not a 10.0 motor on pump gas without severely knocking back the timing...which would negate the gains of the high compression. Coldwar is correct. A cam made for 11-12/1 CR is pretty much dead at the CR's we can run on today's pump gas. You really only have "bragging rights" with that 30/30. Have one of the name cam grinders grind you a cam with loose valve clearances and a lumpy idle so that you make the right noises, but so that it will make some HP in a 9/1 motor.
We used that cam forever ! on the old dirttrack motors.. Cam tech sure has come a long way since then. That said, here is the trick to wake up the bottom end for street use.. #1, advance that thing 4 deg. #2, close up the intake lash 6 thou. and close up the exhaust lash 2 thou. It will be slightly less noisy at idle and way more responsive.. BTW , if you are running a 350 or bigger this cam set up in this manner will even work for power brakes ! ( the longer stroke is less sensitve to a big cam ) This grind in a 283/301 sounds way wicked, and calmer in a 327... and almost mild in a 350,,,In a 400 you can barley hear it.. This is a perfect grind if you want that vintage sound. Dave
i know they don't look as cool as the camel humps but it is going to take about 800-1000 dollars to rebuild them and do the port work. i can get s pair of iron eagles ready to run that will out flow the ported 461s outof the box for under 1000. or for 1200 i can get a set of canfield aluminums with 200cc intake runners and 65cc cnc'd chambers.
I run one in my 61 corvette with roller tip rockers. Rockers take away a lot of the clatter but you still have to work in traffic to keep the revs up. Constantly going up and down the gears in my close ratio 4 speed to keep revs above 3,000. Lots of slipping the clutch to get rolling at what the local police would consider a normal take off. But it sure got a nice idle and is very fun on a summer day with the top down.
Like almost everyone has said it's hard to beat the idle of a .030/.030 but put two equally (and I mean equally) prepared cars side by side, one with a '030/.030 and one with a 350 hp 327 hydraulic and the one with the 350 hp hydraulic will be watching the other one in his rearview mirror before your half way through second gear. It just has more usable torque through the usable RPM range than the .030/.030. Lest we all forget its torque not HP that moves a car. All about whether you want to talk the talk or walk the walk. With that said there are so many grinds available today that outperform both of these cams it's almost a joke to consider using either unless your more anchored in nostalgia than running the best you can. A call to your favorite cam grinder (I prefer Comp Cams) will net you one that will fit your application better than any of the old "one size fits all" grinds of yesteryear. Frank
Modern cam grinds are certainly more efficient, but, I still love my old 30-30 cammed engines. Just make sure you run some gear in your rear, limit your centrifugal advance and then add some back in initial and you'll be lovin' it too Al in CT
I bought a 30/30 cam for my bored out 265 with dual quads, and 10 1/2 pistons ported heads, and the sound and the performance was awesome for the times.We used to tighten up the valves at the drags, and had to check them a lot. Things are different today and I will go for the performance.
now i know nothing about the cam yer speakin of, but my 355 in my 58 has 10.5 to 1 comp and its fine on 93 octane, w booster. its basically a roundy round motor, about 415 hp.
The 327 in my '55 was built by a speed shop in SoCal in the '70s and it has a 30-30. Very nice chop, especially with the required compression. The car has the long "Hemi" style Thrush turbos with short turn-downs, also from the '70s, and it sounds great. Drives as good as any '55 with a nasty old 327/4-speed combo. One of my favorite aspects is sitting at a stop light and seeing people stare at the snarling beast as it rumpity-rumps and spews 108 fumes. Green light--see ya.
My avatar coupe has a NOS 30-30 Duntov which sounds wicked at idle and performs awesome at 11.5 CR with stick tranny. Mechanical lifters like to be noisy.
