The Cal-look Lounge

Well guys as the title says - OLD SKOOL CAMS - Lets here your thoughts  :)

I am in the planning stages of my engine for PROJECT 66 which Mr Keene is putting together for me :)

Its based around an 82mm SPG Roller Crank with a set of 92's (2180cc) with an original Rimco case that was especially clearenced for an SPG crank, I have also lined up a COOL pair of real old skool 70's heads with 42x35.5 valves  ;D

So my question is: WHAT OLD SKOOL CAM WOULD YOU USE AND WHY  ???

I look forward to hearing what you think  :)

P.S I DONT WANT A LOAD OF POST TELLING ME NOT TO USE THE SPG - I AM USING IT AND THAT IS THAT  ;) :)

No Lee don't use the SPG  ;D

Engle 130 or 140

Engle 130 with 1.25's - correct  ??? :)

A 140seems alittle hairy for a "street car"  :o :)

E100

What happened to the "WHY" part of Lee`s question? ;)

K-8 and i don't know why, but bergs engine was same CC and that cam. 12,?? on the strip.

Hi Nicolas

With that crank i would not use a bigger cam , if you make Rpm's it will not work . Sorry to say that but it is so . Old school is fine but don't use parts that do not work good .

Udo

because off the SPG crank breaking?

W120 with 1.25 rockers or w110 with standard rockers 8)

Please explain  ??? :-\ :)

I was wondering that too  ;)

what about lil woper?
i think it turns some rpm :)

Isn't that the whole point of a roller crank? So it revs like there is no tomorrow??

These cranks are not strong enough for big motors . they bend , break ... ! The bearings are not good for this applications . I only did one engine with this and it did not last long  :(

Udo

Going with super light JE pistons will give the crank a easier life... and perhaps a extremely light flywheel can be a good idea to avoid flexing of the crank?

THANKYOU Zach ;) :)

As I said before NO ONE is going to talk me out of this engine (Richie has tried his hardest trust me ;)) - its just something I have ALWAYS wanted to do, I know ALL the risks thats why the roller crank is being FULLY stripped and rebuilt with NEW needle rollers, it is also being PINNED and WELDED, as well as having an original GERMAN flywheel WEDGEMATED to it - I am only gonna be running 185's on the back of the 66 and I don't plan on launching it at 7k on a set of 7inch pheniox slicks ;) :)

Right now we have all that out the way lets get back to CAMS - Which would you run and why ???

Before choose a cam, choose the use you will really have of the car.

If you plan to use it as a cruiser with some adrenalin shoot from time to time or a street warrior I think you will not have the same cam choice.

And  I think that the W serie from Engle is use since the 70's. A w125 seems to be a good all around cam if you read what the guru write on this forum.  8)

"a street warrior" you know me dude thats EXACTLY what she's gonna be  ;) :)

Matt did sugest the W120 with 1.25 rockers - you see to be real old skool i can only use 1.25's  :-\ :)

I'd run stock rockers. I don't think many street cars from the old days were running ratio rockers, though Sarge could answer for sure. I think Mahaffey had a W130 in his split.

Carlos has an Engle 140 in his car and it idles and pulls like silk.

Or to be real old "skool" modify up some Porsche 356 or GLAS rockers, like Gene Berg did.  ;D

are you going to run close gears?

Hmmm interesting...... I see what yourr saying about ratio'd rockers BUT don't you "need" them with certain cams :-\ ???

And yes it will have pretty close gears but I am toying with a 5 speed but I am building the engine first then build a box to suit the power curves etc  :)

FK series cams are made to run 1.4 or 1.5

W-series were for stock rockers, although later, 1.25's were added in some cases.

Is a 5 speed old 'skool' though Lee? Not trying to start anything, but if you are trying to build a car that would allow you to travel back in time...very cool....  you'd want to run short-geared 4 speed and Crown solid mounts and go deaf!  ;D

this would be cool, Lee

The 92's are also "old skool" but of unknown make - most of these parts come from an old drag/racing engine built back in the late 70's/early 80's but was never run/used

I have also lined up an original Thunderbird 1 1/2" header and original dual quiet packs  :o :)
I'll also be running a modified/custom "brazilian" Fanhousing with chrome backing plate........

I'm giving away way too much here - anyway here is a sneeky peek at the COOOOOOOOOOOL heads  ;) :)

So any more thoughts on a Cam  ??? :)

130. Lets hear that motor sing!! ;D

I agree.

How is car geared Lee?

Just been think about this i had a 2180cc with a W125 in my old 66bug. 1st time out i run a 14.6 and by the time i took out my tent and the rest of my camping gear i got a 13.9 1/4. ;D

I am gearing the car to the motor - I thought it was best  :-\ :)


Hmmmm interesting  ;) :)

What about rockers though guys  ???

yes gears and motor should ideally match

I still say use stock rocker arms, Lee.

Cool thanks dude  :)

Empi 1.4s and a fk87.

Lee I would use a W-140 Cam with stock Rockers on Berg Shafts this cam puls real hard and Idles Great and is smooth all the way threw the power range

I think you could use a 125 / 130 / 140 because your buggy is lighter then a sedan.  Do the Berg shafts like Shubee says and some stock rockers like Jim recommended.  I like OEM 911 Porsche valve screws (the underside of the rocker has to be clearanced a bit on a bench grinder for the swivel to move fully).  I had a look in Berg's old Technical Article book and here's what he had to say about 1.25:1 rockers on cams designed for 1.1:1 for what it's worth....

Thanks Buddy but this lil monster is going in PROJECT 66  ;) :)

Hmmmmm, in that case, use a VX93 with 1.8:2 rockers on rifle drilled shafts and forget all that other hogwash I posted ::) ;D

Talking about old stuff, take an old catalogue.  ;)

neat old info there... interesting jetting on DDS 48IDAs... 40mm venturi, 155m x 155a jets. I ran my car that way for a while last year (before I upped to 42mm)

this is what the book say about IDA use on the road.

There is lot's of interesting info how about they built engines back in the days. Check the last scan with the Don Burn drag setup.

Hey Thanks JF that is some seriously cool information - see those guys really knew how to get HP  ;D

1700cc making nearly 180hp  :o

I've found all this info in a small book call "all engine 1200cc to 2300cc". From 1977.  ;)

mr bill mitchell 

hey j-f which catalog is that? I really dig old specs like that. Thanks for posting.

sorry, you posted the title while i was typing single fingered.

I make another post with the scan I did. ;)

 

it's a catalog from motion minicar i just want to go on david mayes website and google don't found him ??? i'm sure there that catalog on dave's site
 the web site is delete ??

Since he passed away a few months ago I guess someone took the site down :'(

I wondered who edited this catalogue  :). Thanks Fab.  ;)

 :'( :'( :'( I wonder who will be making an offer on his collection  :o :-\

It's sick to think of such a thing, but I can't say that I'm not guilty of it. :-[ But it matters not to me as I bearly have a pot to piss in right now! He had a ton of cool parts, it would be good to see the sale and proceeds go to his family at least.

Hey don't get me wrong dude its just something someone mentioned to me the other day - it shocked me a little too  :-[ :)

Anyway back to CAMS ;)

One thing I did want to bring up was the whole ratio rocker issue (I know Jim ;)) Any thoughts people  ???

Another old shool setup.  ;)

The cam seems to be something as a w120. And it runs 14sec  :o That should be a nice engine.

Lee, if you're still interested, I may be able to get you a lead on Isky cams for Volkswagen.

Hell Yeah!
there aint nothing wrong with them SPG's ;)

188hp on the dyno and rev's to the mooon!

(http://i32.photobucket.com/albums/d18/autocraft/martin_taylor_02.jpg)

Spec's (from memory)

SPG crank
DDS barrels & Pistons
Engle Special Grind cam (no numbers on it)
1.5 rockers
ported heads
48 IDA's
12lb flywheel
010 Dizzy

Drives on the road like a baby ;)


Long live the SPG! . . . . . ..(in old retro cars ;) )

Very cool seeing those scanned articles. Interesting hp figures qouted though...  185 hp on a 40 mm Weber with 32mm vents? And over 200 hp on a 39mm inlet valve! Those were the days! :)
Got to get me a time machine and an empty suitcase :)

well it looks like Gary H has an original Engle 130 (with lifters + cam gear) for me, he thought it would probably be best for a "Street motor"   ;D

I'm thinking that K-8 was the first generation of the K-8, I believe had more dur., not sure on lift.
