[1968Chevelle300Deluxe]

hey i have a 1968 327 L-79 325h.p engine in my 68 300 Deluxe and i was wondering what a good cam might be my dad said he had an L-79 once in a corvette and put a 300/300 cam in it by General Kinetics and it ran like a son of a b:angry:h and i was wondering what a good cam company these days makes a good 300/300 cam thanks

Crane makes a blueprint replacement

 

[1968Chevelle300Deluxe]

really ill have to check into that thanks

cam part # is 967601 in the ole Crane catalog

I used the K 1104 cam 'n' lifter kit from Summit. Generic grind; nothing fancy. I slapped it in my 400 intending that it would be a temporary cam until I learned enough about cams to choose a "good" cam later. I chose it because it looked similar to the 350-horse 327 cam. And--it worked so well that it's been in there for many years. Yes, I'm probably giving up some power over a UDHarold grind--but replacing this cam is just going to have to wait a while longer. http://store.summitracing.com/partdetail.asp?part=SUM-K1104&autoview=sku

Same 114 degree lobe center; a hint more lift and duration.

Hard to go wrong at ~$90.

I am quite sure the GM Dealership still sells that cam in the GM Performance Parts catalogue.

What I have always used to replace the L-79 cam is now called the Lunati 301A7LUN, [email protected] .0045", 221/[email protected]", .454"/.454" valve lift, and 114 LSA. These have gone 100,000 miles on the street, and I used it in oval track racing for those classes that required a vacuum rule. It works from idle to over 6000 RPM, with peak power about 5400. It also works all power equipment.

UDHarold...if I may ask a question sir...what are your thoughts about the Crane cam 222/467??? Does that little bit of extra lift help make any noticeable torque gain as compared to the Lunati you mentioned??? Do you lose some vacuum as a trade off???

THANK YOU!

I have never seen a dyno comparison between the Crane and my 276, but normally I have more aggressive opening ramps than the Crane cams do, which helps produce more torque and a nicer idle. Crane and I both close our hydraulic profiles very close to stock GM seating velocities, which keeps valve train noise down, and extends cam and valve train life.
Quite often the trade-off in increased port velocity---better cylinder filling---and a more-rounded nose---same thing---makes up for the .010" extra valve lift. The part of the cam that does the most work is from TDC down to about 75* ATDC, long before max valve lift occurs. At least it's seemed that way for the last 28 years.........

might want to look into the isky 274 mega, it's 226/226 @.050" , .490/.490" lift on a 108lsa. Sounds way better than the old L-79.

Wow! I see where the 301A cams are $198 at Summit now. Doesn't look like the P/Ns include lifters. Am I missing something? Voodoo cams are around $130.

I would put Harolds 268 Voodoo cam in that 327 with the right springs and 1.6 rockers, set and forget it, and then hold on.

Reading right along..

Hi Harold..

One thing that's being missed here if it is a 327 engine and that is they like rpm's!!

Go w/ a solid lifter cam, imho!

Probably like 10 to 1, 280 and 11 to 1, 290 for starters. Harold, please spec one here for a generic 327 engine for the guys to at least consider b/c my 1st thoughts are "old-school" like the old GM -097 and 30-30, and Z-series Isky's, and I know you have SOTA out now so PLEASE advise/sell to us.

And imho, you can't go much better than a UDHarold spec'd cam.............

And I don't get any kick-back, He, He!!

Paul/pdq67,

What I have been using for about 25 years in the 327 Corvette is an UD 264/264F110, 264 at .020, 232 at .050, .470"/.470" gross valve lift, and 110 LSA. The first customer I put one in called me to say it would fill the interior of his 'Vette with tire smoke whenever he wanted it to.
For those who think that is too small, I have the UD 272/272F10, 272 at .020, 238 at .050, .485"/.485" gross valve lift, and again, 110 LSA.
Both of these cams will go 100,000 miles on the street, and require setting the valve lash at least once every year.
I use the 272F also in some oval track cars, and as a replacement for the BBC LS6 cam.

Geez guy's,

And ta think there are those out there that are still going after, "Bigger is better" Which is fine IF you are NOT a high RPM motor guy when a hopped up 327 will dust a bunch a bigger engines easy!

And a 327 will still get some decent gas mileage to boot.........

I can take a 292 and dust a 383 so go from there BUT it won't be street engine like my old junk301 was.

if you have a rochester quadrajet it will be nice for gas:yes: but if you have a demon watch out well there goes a tank of gas in 5 mins:noway:

:who is this: put a 264/[email protected] on a 104 lobe center. Wth a 5800 stall you can drive it anywhere, I do. :who is this:






sorry, couldnt help it.

You wouldn't be too far off with Comp's 270 Magnum.
