Looking for a solid f/t cam to install in my 327.
Years ago, I ran a 292h in an 11 to 1 350... and absolutly loved it.

now i'm rebuilding the 327 for my vette and want a solid cam that would at the very least perform as well as the old 292h did in that 350... i know i'm loosin 25 cubes, but i'm sure switching from hyd to solid will help pick up a few ft/lb and a few HP.

i want something that will not be too gnarly becasue I routinly drive this car and do not want to be pesterd by having to check valves every single weekend.

I'm thinknig something on a 110-112 lsa, with 240-250 duration at .050
I'm using the old GM fuelly heads which have a mild port job and seem to flow quite well up to about .500 lift... so a nasty solid roller is out.

i've looked at the comp 294s but I'm afraid to run anything off the shelf these days.

any help would be great.

Thanks

Have you looked at Comp. cams XS282S?
.520/.540,duration at .050 244/252,110 L/S.

 

[Dave427]

The 294S is a little large for a 327, I would go one lower like the 282S.

[aaronz28]

was looking at that too....

the trouble with the XE stuff (that i'm told)

i have 11.25 to 1 compression.....

with smaller cubes i'd like to keep it so i don't have to run it on 100% racing gasoline.

i don't mind mix, but with the prices of Gas these days... sheesh..

Please consider an Isky Z-27 solid lifter cam.

And even this cheap PAW PN 10341 solid lifter cam!

In my New York phonebook sized PAW cat, they call it a 264/246, but I think it may be their rebox of this Elgin solid lifter cam;

E-1133-P; 280/246, 108/106, .498”, Lash, .030” and .030”

$45 + S&H so the price is right!!

PS., oh, and btw, the PAW solid lifter cam is in my bedroom closet now.

I'd suggest the old Comp Magnum 282S 12-223-4.... with the small motor, you don't really need the bigger exhaust lobe of the XE series.

Not sure what's wrong with "off the shelf"?

 

[Guest]

He's talking about that it seem's that CC's cams seem to be going flat more that others and I just figure it's b/c they sell MORE cams than anybody else so it come's up more often, THAT and our cat-pee oil that we have now due to EPA cat-life!

If you don't have to run a cat(s), I'd use whatever oil I wanted to and just ADD a bottle of whatever EOS has turned into and go!!

pdq67

PS., and I'm old-school and tend to like the older, easier on the valve train and lobes, 268HE type cams vs the XE's!! I know I'm leaving power on the table, but if I was to ever DD mine, I want it to last at least as long as my old -151 cam did and it was still going after several years FINE!

I bet an XE won't do it?? BUT I figure UDHarold's cams may just like he says.

I would use the 268 Voodoo hyd ft, set it and forget it. That cam would be great in a 327 IMHO

 

[trmnatr]

Crane has two cams that would work great:

-244/252 @.050 .518/.536 106° lobe seperation This is a Saturday Night Special
-244/252 @.050 .518/.536 112° lobe seperation This is a Powermax cam

If memory serves you have a 4 speed so i would use the 106° lobe seperation cam

IF you have a good flowing exhaust system, and a good exhaust port in your heads, consider a single pattern cam to add a little more torque to your 327. For small engines, I tend to be much more conservative that most people, if it's for a daily driver. In some respects, the Chevy engineers had their act together when they chose [email protected]" for the 350 HP hydralic cam. A hydralic in the low 220's on a LDA of 108 will make a nice sounding and peppy 327.

However, street roller cams are not necessarily nasty. The CC 280 street roller would really wake up your 327, and be a good daily driver. A roller will give you much better performance with any head, even stockers. It's duration @.050" is 230.

A roller cam gives the best performance obtainable, no matter what the duration. You will even get better performance with a roller with stock cast iron manifolds. A roller with give less exhaust dilution and idle smoother than a flat tappet of equal duration.

It is my opinion, we need to kiss flat lifters Good Bye. They impose much greater compromises than rollers. The factories switched to rollers and gained performance and mileage.

There are probably better street rollers than the CC 280, but that is one I have experience with and I know will perform well. It will sign off about 6G's. That is good enough for a street machine, and it provides good torque. I had one in my 302, with 3.31 gears, and a 2.5 Muncie with 1 5/8 headers, also 11:1, with the stock Z-28 manifold with 1" spacer. I should mention that I went from the 140 Chevy cam to the CC, so the change was dramatic. I swapped the 4.56 rear for 3.31's to drive to Chicago many years ago, and never switched back. Since then, I have developed a different philosophy: make the car run with 3.31's. (I ordered a new Monte in '73 with a towing package, and it came with 3.42's. I thought those were too low. I regularly ran 5.12's or 5.38's in my '55 Chevy, PG street car. I won more street races with that car than you would ever believe.)

PDQ67 would probably recommend the CC 244 street roller. That would add some RPM, sound good, and turn your car into a low 12 second machine. That plain, old, run of the mill, roller cam will make any engine run good. But, I would use it with at least 3.73 gears and a 2.5 first gear.

I know you said you wanted a solid flat tappet, BUT, IF you go with a mild hydralic roller, you can have your cake and eat it, too. Take a hint from John Lingenfelter.

I built a customers 355cid vette engine with a hyd roller and it is impressive with the performance it has, he wanted race fuel so we did a semi low compression of 10:1, It will run on pump gas but he likes race fuel so we tuned it into race fuel, if he is out and runs low on gas he can fill up with pump fuel and he has done so.

With the compression being 10:1 we installed a hyd roller cam, 222/230 @.050 .509/.528 108° lobe center installed at 103°. You would think this cam would be done at 5,500rpm being a small hyd but in fact it will pull through 6,000rpm, maybe more as the car is very wild and he has to lift alot and traction, well there is just no traction with a '77 vette with this combo

We run Dart iron eagle 180cc heads with H-11 valve springs set up at 160 pounds seat ressure @ 1.725" on the intake and 147 seat pressure on the exhaust @ 1.750" {we set it up like this due to valve weight with Manley valves}

The open pressure is set up at 373 open pressure on the exhaust and 383 open pressure on the intake, These open pressure's are at cam lift. It does run a Torker II with a 1" spacer and a 750BG Speed Demon we tuned into the combo

The car is a 4 speed Super T-10 with a 3.73 rear. It has had an electric Holley fuel pump installed. The ignition is a stock HEI with the pertronix hi performance street kit which i must say is very nice and it seems to perform on his car very well, i was a little scared of using it but it seems to work great. It has Crane 8.5mm Firewire plug wires on it with Autolite AR134 plugs

We put Clevite "V" series engine bearings in it, Scat Crank and KB domed 11.2:1 pistons {with 64cc heads}, with our deck cc and gasket its 10.1:1

 

[wildman926]

Go with what I have -
Lunati
401A6Lun

adv - 276/284
@ .050 - 243/251
Lift - .518"/.530"
LSA/ICL -110/104
Lash - .026"/.026"

You won't be disappointed....

 

[jeff swisher]

that lunati looks close ..I ran a 292 h in a 350.. buddies car now. I know what you are looking for , and this might help

The 292 in my 350 will pull to 7400 all day long ..with anti pumpups.. well it will pull past that but that is where the safe place in my mind stops with a hydraulic.. and it runs 11.9's with 305 heads .. the sweet spot is 7400rpm..
Them little cams in the 230 duration will not pull like that 292..you need 245+ that is my opinion ..
I ran a 235 -245 .500 -.500 on a 108 and it pulled like the 280H .
Running factory heads i have better luck with single pattern cams..Ported heads of course...(maybe my intakes are just week )

Run the EDM type lifters..And no restrictors, and i think your cam should live a long happy life

Heck, DD, GM's old Duntov will do nicely!!

I loved it in my old junk301!!

So Paul....you`re advocating an ancient cam design AGAIN

So, the leading edge UDHarold design sits in your closet right next to some old dinosaur cam . Right ??

Why, did you even bother to badger UDHarold to grind you a cam, (if an old dinosaur cam would have fit the bill ) in your "humble estimation" and then stick it in some dusty mothball infested closet ???

HOW`s THE 496" RUNNING these days ???

 

[Eric68]

LOL at Steve . . . We love you Paul and your stories, but we've been badgering you to get that 496 running for 7 or 8 YEARS now

But in an attempt to not stray too far off topic . . . I put the Comp 282s in a 327 with some ProTopline 200cc heads and the motor ran fantastic to 6,600 RPM. His compression ratio was 10.3:1 with some small dome pistons so the dynamic CR was about perfect. The ramps on that 282s are not overly aggressive with a forgiving lash ramp so there's no need to get anal about checking / setting lash every weekend.

I would not go bigger than that unless you have some big dome pistons in it -- if you have the small domes and 64cc chambers your compression is down around 10-10.5:1 and you would be better with a cam that is 280 'ish on the seat and 235-240 @ .050.

For the street:

I have delivered to Lunat 5 SBC solid lift VooDoo profiles, and 5 BBC solid lift VooDoo profiles. They were designed to the .050 and valve lift numbers of their previous designer. They are making them on 109 LSA for the short durations, and 111 LSA for the bigger. Some of them on different LSAs will make fine oval track and bracket cams.
Here are the .020, .050, .200, and lobe lifts/valve lifts of the available designs:
SBC
262 233 145 .3367"/.505"
270 241 153 .3467"/.520"
278 249 161 .3600"/.540"
286 257 169 .3734"/.560"
294 265 177 .3867"/.580"

BBC
262 233 145 .3353"/.570"
270 241 153 .3471"/.590"
278 249 161 .3588"/.610"
286 257 169 .3676"/.625"
294 265 177 .3676"/.625"

The BBC 286/294 on a 107 LSA will be very similar, and I hope slightly better, than the old UltraDyne 288/296F7, a good 10-sec cam in most BBCs, and the SBC 270/278F7 will be a fine 2-bbl cast iron exhaust cam on short tracks.
Other combos are possible, give me a call.
Lunati has been making the SBCs for about a month, and are just starting on the BBCs this week.
