I have a 67 327 rs with a 4bbl 600 carb. The car is putting out 260 hoarses. I have the powerglide tran. I still have the stock cam and intake. Any ideas on the right combo for a performance intake and cam?

 

[onemorecamaro]

Sounds like you have plenty of carb for this engine. Crane makes 3 good Energizer series cams that should work well for you. Part # 100032 is the mildest grind and should work good with stock exhaust manifolds. Edelbrocks 2101 Performer intake is also a good choise. These pieces should pick up your low end torque and improve the "fun to drive" feel of your car. By the way the other 2 grinds are 100042 and 100052. You can check them out on Crane's web site @ Crane.com

Good luck,

John

I second the Edelbrock Performer RPM intake, I bought the entire package for my last small block, cam, lifters and intake, and it ran great!!!! KZ

I agree.I have the edelbrock cam,lifters,and intake.My car runs very strong-I strongly suggest this combo.

 

[80 350/425]

sorry-i meant to add the "performer RPM"kit i forgot to mention.

 

[CORNHOLIO]

Yea that kit does allright, I like the idle the best with uncorked headers and a slightly cold day. Gives me chills, you'll like it.

 

[my69gofast]

Agree, can't go wrong with the Performer RPM manifold.
I think cam choice depends on what you're looking for. The Performer RPM is a pretty big street cam for a 327...don't think it's a good idea without a looser converter and deeper gears. A good all around street cam is the Comp Cams DEH 275 (219/229@.050"). Big enough to make power and easy to live with in a daily driver.

My69gofast,

Right on, I'm pushing smaller cams because I feel that they work best in the street rpm ranges. pdq67

PS. A better cam for a 327 might be around 210 degrees at .050".

 

[RickB1B]

Guy's do a search on this. There has been a lot of discusion on which cam for a 327. The basic answer is, use something between a 260 and 268. The 260 gives more torque and the 268 a little more hp. Anything bigger than a 268 will not be a good street engine. A 327 need the torque. BTW I used a Crane 266 kinda in between. Works great. Desk top Dyno tells me I'm in the 345 hp range.

 

[bravewink]

I'm with PDQ67 on smaller cams. I'd agree with somewhere between 208 and 214 @.050". You get better off-idle response with smaller cams and better throttle response with dual plane intakes. I don't think you'd need to go bigger than a Performer intake on a 327. It'll flow enough to support your 327 up to 6000 RPM. If you have the time and money, some port work to the heads combined with a smaller cam will give you very impressive results.

 

[sweems]

On the dyno program I've got, keeping the same set up and just changeing cams only made a 20hp difference (peak). I used the 262 xtreme energy comp cams specs aganst the edelbrock rpm. I don't have a tourqe measurement. Its seems like the real power comes in the heads and the amount of porting you have done.

Thanks,
Shane

I have three cams for you.
CompCams Extreme Energy PT# 12-234-2
211-218 duration at .050
256-268 advertised duration
447-454 lift
110 lobe seperation angle

CompCams Dual Energy PT# 12-208-2
211-221 DUR. at .050
265-269 ADV DUR
110 LSA

Ultradyne-NO Part number given
211-221 DUR at .050
266-276 ADV DUR
441-454 lift
110 LSA
You will notice that all of these cams have one thing in common,110 LSA.This LSA will give you increased torque over the same cam using 112.The downfall of this 110 over a 112 or higher is decreased vacuum at idle.But it shouldn't be a problem because this cam is pretty small.If you had a TH-350 trans you could use a larger cam with more intake lift(454)and duration((218)at.050.Anything larger should be reserved for use with a 4 SPD.
Get the "NEW Performer"(Not the RPM).The new Performer is a better design than yesterdays.Check out what David Vizard had to say about it at http://www.davidvizard.com/prod1a.htm

Get yourself a set of 1&5/8 inch headers and 3.31-3.42 gears wile you are at it.

All this talk about changing cams how hard is it? How do I do it? I dont have to take the engine out right?

ekg,

Don't know about how much hassle it is to install a cam in your car. Maybe the engine will tilt up high enough or maybe you might have to remove the grill. Heck the grill center member might be offset just enough that you won't have any trouble at all.?? But the cam will be worth the trouble.

Hardest part about the whole deal is getting to the front pan bolts and pulling the harmonic balancer off (as usual). Good luck if you bite for the install. pdq67

I didn't catch if you've added headers or not , but at the cam swap would be a good time to add them too. pdq67

 

[pdq67]

Back again,

Check out this little cam by Camcraft, 266/266, 109/105, .414" lift. 28-58/66-20 seat timing. The little sucker might be just the ticket for a slightly warmed over 327. Should make in the neighborhood of 345hp/375t easy with open headers.

It will probably "cackle" because of the short lobe centers, but should make good torque down low. I think it was mentioned in a prior post. pdq67

 

[my69gofast]

Bottom line is that there isn't one perfect cam for your 327. A "streetable" cam can mean two totally different things to two different people. You have to decide what your intended application will be. That really affects cam selection more than the fact that it's a 327, which isn't that much smaller than a 350. A cam in the 211/221 range would make good power with almost no effect on everyday driving. A larger cam might be right if you plan on a lot of strip action and don't mind some tradeoffs at low rpm. A cam with under 210 duration really isn't worth the effort(at least to me) unless you are more concerned with a near stock idle than power.

 

[ksmith]

Be carefull of too large of cams. I have a 268 extreme energy cam and had to put a stall converter in the 350 transmission. I love the cam though and the performance is nice too. Has that big lopy sound.

 

[Stingray]

I would go with a CompCams XE262 and a Edelbrock performer RPM intake.

I understand the reason for mild cams in daily drivers but most of these cars are now over 30 years old and are really Sunny Sunday stomp it once and take it home. There is nothing like a 327 with solid lifters screaming up to 6500 or even 7000RPM with a 3:73 rear to make you feel great. While it won't be much until it gets to 3500rpm, hold on after that. Also, why does everyone want an automatic. I swear by my Muncie, my Hurst shifter and the Centerforce clutch.

Therefore, if you want a daily driver buy a Toyota or a Honda and wear a disguise. If you want fun, stuff a decent cam in that 327 and go for a ride.

HEY! Stop bashing Toyotas! I have one, but it is NOT a daily driver, the slciks hate rain!
