OK, 'Rod or Rumble',

The thread is titled.......... 'Street Performance'

I think you're smart enough to know what that means.......

Not 'Pro Street' or 'Radical Street'

And a Camshaft that has a 'friendly' Price Range.

Rod? You must be trying to F-bomb with me. So be it.

The title "street performance" is subjective. Your opinion need not apply.

Pro street or radical street is also not your call. You assumed the example I have included the pro street look.

Most cam and lifter packages are cost friendly. But selecting the Comp Cams product that requires a spring change is not! Since machine wrk to the heads is needed in order to use them. Sorry again but I don't think a old LA would but acknowledge it could, have decent enough spring that are good for the new cam.

Is that 'Camshaft' user friendly.....

'Tic, Tic, Tic, Tic'

That doesn't seem 'Mild-to-Moderate'.

That seems to be a 'Mid-Radical Street Cam'.

Is that in a 4-Speed or Automatic.

Mopar Performance #P312-P4120653AE

* Mechanical Camshaft
* 528" Lift
* 284* Duration
* 241* Duration @ .050"
* 112* Center-Line

* RPM Range...... 2900 to 6900 RPM's

A} You have to change the Rocker Assembly
B} Push-Rods
B} You have to change the Valve-Springs and Retainers
C} Then, possible Valve-to-Piston Clearance

That doesn't sound like a 'mild-to-moderate' Street Performance Camshaft,
to boost performance at a 'relatively mild cost' does it.

You know, this is an information thread, not a 'Down the Drain Thread' Mr. Plumber.

Your opinion need not apply here again. It also seems preey clearly. Have not run one in the street.
Where did you get the rpm band from?
Must change rocker gear? LOL, any decent build would step up in the valve train Arab which in muses rocker arms.

LOLLOLLOLOLO AND OMG!

Seems to be your thread your way. Go back to MoParts!
 
Rumble-Fish,

Again you fail to 'grasp' the Thread Title.

Street Performance Camshaft.

A 'general' cost Bumpstick that works well across the board for
a mild-to-moderately built 340 or 360.

You still can't come up with one.

An Hydraulic Camshaft that will work with Stock Valve Train and Stock 340
Valve Springs {Load-Rate #240 lbs. w/Valve-Open}.
 
I like the XE268 and XE262 Comp, the older High Energy 268 Comp, the Crane 693942 and it's smaller cousin 693902, the Summit K6901, The MP 280 DCC-4452992AE or .528. You really can't go wrong with something in the 220-230° @ .050 and .480-.500 lift unless you don;t degree it - especially the MP. IMO cost is not a consideration as long as it's a flat tappet.

Edit - I stay away from Lunati VooDoo as they recommend dual springs which mean more head machining cost. I also don't consider using a stock 340 spring on anything but the Summit.
 
Moper,

Good Picks.

The Compu-Cam 268-H 'High Energy'

Was kind of popular for awhile.

Lift.......................... .454"
Duration.................. 268*
Duration @ .050"..... 218*
Lobe Separation....... 110*
Center-Line.............. 106*

RPM Range.............. 1500 - 5500

A small 'step' over the Stock 340 Camshaft.

The guys with the 'moderate' 318's liked it a lot.
 
Had this in my 73 Duster....sound was great...performance was outstanding...

HE3038AL 230/237 @ .050 .515"/.535 110 4 degrees advanced.

Had alot of initial timing cranked into it....
 
GM was smart enough to put solid cams in some of the musclecar engines, chrysler with the exception of the Hemi was not.

Now there is mention of some ridiculous spring rate limitation... why wasn't that nonsense mentioned at the beginning to limit the choices to pussy sized hyd street cams :)

If you take any of that as a personal attack, it's not...

Drain-O :) :) :)
 
I've run a Lunati 60403 in a few engines in the past and loved it. I believe Lunati changed the part number since the last time I bought one though


Lift : 494 / 513
Duration : 268 / 276
Duration @ 050 : 226 / 234
Lobe Separation : 110
RPM Range : 1,800 - 6,200

Yep.

Don't forget the weak stock spring limitation
 
Well,

I guess many of you never worked in a 'Professional Machine Shop', where
you have to make a choice for a customer who asked 'you' to pick out a
Camshaft for his 'Street Performance/Daily Driver' that had a 340 or 360
in it.

I could have easily said , 'Yea', lets throw in a Crane Compu-Cam with a
.570" Lift 'solid-cam', and then send him on his way.

Now, contributors {'Moper', '74 Dusted' and '70 AAR Cuda} added something
positive, a Camshaft that worked well in a 'street performance car'.

Old Man Rick, I understand on why you passed......
 
I have ran both the comp 268/.454 and the luinati 290/.480 camshafts they are great cams for the stock modified engine.

One of my favorite camshafts was a trw can't remember the specs for sure but I think it was 290 I 300 E duration .447 Inatake .450 Exhaust lift. Dont remember the centerline. This camshaft was bought out of the local Big A Auto parts store. I put it in a 8.8-1 360 stock j heads with a torker 340 ran great in a 3500 lb sattlelite.

I personaly like this thread so lets keep it away from the drain guys lol. I think most of us know what your intent with this thread was. It seems to me the longer people are around here the more they have to nit pic to have something to talk about.

LA 1970,

I remember that TRW made a boat load of Camshafts for the Chevrolet,
but there was a 'limited' choice for the Small Block Mopar.

They had one called 'Street or Marine' for the 340 and 360 which was an Hydraulic,
that had something close to the Chevy Specifications.

It may have been the 'biggest' Hydraulic Camshaft offered for the
340-360 by TRW at the time.

.450"/.460" Lift ~ 272*/280* Duration

I had a comp 262h in a stock 340 ran nice .
I also had a mopar 284/484 in a 70 340 stock 040 rebuilt
I liked the 284/484 sounded good and pulled hard !
I also liked the 262h it had a slight lope and good bottom end.
I have a 292/509 in my cuda now sounds nasty pulls well after about 2600
Not really street friendly . Car is a 4speed .
 
The old 214/224 444/465 works pretty good in most anything, including 273 and 318's

Be upfront about your limitations and don't deride other suggestions when they don't fit "your" idea of a street performance camshaft.

Have fun.
 
To be really useful, I think you'd have to start with a stock car and make a list of suitable cams categorized from conservative to aggressive, with sub categories for important characteristics. Like maybe where the power band is on the rpm scale. Just deciding how to categorize them would be difficult, likely impossible with a bunch of cats like we have here.

Then you could specify what kind of engine upgrades would warrant an upgrade to the cam and make a list of cams that would complement each upgrade.

Then you could take all that fantastic info and make it into a book that would simplify camshafts for everyone.

Call it "Camshafts for Dummies". :blob:

If it happens, the next book could be titled "How to herd cats" :)
 
Idaho,

I like the way you think........

Being from a Professional Machine Shop 'family' in southern New York,
{1967 thru 1999} we used the term 'Street Performance' as,

More of a general up-grade, usually '2-Steps' over Stock.

Usually cars with 3.55 or 3.91 Gears
* Headers
* Competition '3-Angle' Valve Job, but no port work.
* Aluminum Intake Manifold

Most had 'stock' Automatic Transmissions and Converters.

Carburetors and Ignition was pretty much 'stock.

That is very hard to put down as a 'Thread Title'.
 
Remember the TQ20 and TQ30 cams from back in the day.....they worked okay.
 
Hmmm.kind of posturing, by the O.P. You're credibility, sinking quickly....

Yeah. I was the manager at a NAPA machine shop back about 90-92. I remember very well in their engine catalog, that camshaft was the *only* one listed as an "HP" grind......and for ALL makes. lol They worked better than people gave them credit for, I think. We had a TRW book for anyone wanting to go larger and then of course Summit.
