30/30 cam specs

Can anyone tell me the spec's on a (30--30) sbc camshaft? I have one that came in a motor I bought. It does not have a part# on either end but I did find some other marks----EP1,---D6----14 and a blue stripe. The previous owner said it is a 30---30 solid lifter cam,,it did have the solid lifters as well and it was made by COMP.CAMS. thanks BP

30=30 specs

The guy wasn't sure if he bought it from Comp. or Crane, would the lack of part #'s make you think Crane or GM maybe.? BP

A GM cam will have a pink paint marking on it.

repro of the Duntov 30/30

Those cams are reproduction of the cam Zora Duntov designed for the Mech FI 327 back in the 60s. They are a noisy cam in the low rpms.

. Although the 370HP LT1 350" was listed in early 1970 Corvette advertising literature, it supposedly never actually went into production and a 244/254 cam was used instead and all engines were the 360HP... to give the new LT1 a fatter street torque curve than the 302"...

. I don't know if the 30/30 cam had to actually have .030" lash... or it was just to keep the HP down and the drivability up... need re-adjusting less often... tighten the lash up for racing... giving more lift/more duration...

Perhaps use the cam that is used in this article

L84 Fuelie Motor On Engine Dyno - Vette Magazine - View All Page

My Father bought a crate L76 327 (same longblock as fuelie 375hp L84, just rated at 365hp with a 4bbl).

His best running was with dual 4bbls, 5.13 gears, 4 speed trapping at 7200rpm. Low 14's was the result. This was Dad's daily driver.

In this car (when Dad was selling idiamondback in the early 70's)


Same car-1995(Diamondback at car show Dad and Mom hosted, trailered by then owner)


Same car in 2008(on trailer in Dad's driveway-Dad's Sothern Belle on the ground) diamondback was bought by to be restored, but another car was used to build clone #1



Clone #1 2008


Left to right
Diamondback, Southern Belle and Clone #1


Fins


Diamondback in 2013, back in Dad's driveway, back in the family after 40 years.

Of course minus the L76.
The 30-30 was great for its day, but so much technology has advanced, a newer grind is in order for most applications.

peace

. Seems about 10/10ths or more slow for the power and gear... must have been the skinny tires...

I had a Crane blueprinted 30-30 cam in my car for 19 years. I pulled it when I built a new engine. It was in like new condition so I marked a boxed the lifters and set it aside. A buddy wanted to use it in build, he measured the lift at .434" lift. I really don't think the cam was worn nearly that much, the lifters still had a crown and the lobes were in great shape. I have to wonder if it was ground with that lift, wish I had checked it when I installed it in 1984.......................

They used to RENT slicks at the track, they were skinny back then though.
He only ran the dual 4bbls, 5.13's once, for a grudge match against Jim Oddy, which Dad won.
During normal racing, Dad was known for not launching hard, his friends would tease him about it, but they didnt have to drive to work with the car the next day. I do remember him having rear end issues on one weekend.

Who knows, perhaps I am confusing ets from regular weekends and that one "special event".

I also remember a story about Tech. saying his collectors were too short, so he attached soup cans to pass Tech.

I'll do some digging and see if I can get some more info.

Stock 300 hp 1964 Vettes would ran low 15's,
L76 327 V8 340 bhp @ 6000 rpm, 344 lb-ft @ 4000 rpm. Ran 14.9
396 L78 ran 14.1
Gearing was unknown for these stockers.
