any body running the voodoo 60103 cam in a small block? the reason i was wondering were there initial timing and idle in park are set just curios i dont know what the problem is but somethings not right with mine im using manifold vacuum and 20 btdc to get 34 total idles at 1100 and in gear 750 with a 22-26 stall

That cam runs awesome!
Could it be possibly that you have a few valves too tight? Is the vac readings stable?

i dont believe they are tight im sure i adjusted them correctly i will do a vacuum test today and let you guys know

Your mechanicals are likely coming in too soon. install a stiffer spring on the distributor. I just went through this on a BB, same cam though. Also, what cfm is your carb, type?

but somethings not right with mine im using manifold vacuum and 20 btdc to get 34 total

I just reread this...
Need more detail on how you've come to get the 34 degrees total timing. This is with the vacuum advance disconnected, correct??

It's all a matter of getting your intial timing,mechanical advance(replace bushing with larger one),when mechanical comes in fully (advance weight springs),total timing, & vacuum advance along with your carb all dialed in correctly for the cam your running.

What you describe happens all the time when people install perf cams in their motors.

A good place to start is approx 18 deg intial and 20 deg mech (MAX)for 38 deg btdc total timing.

Then you should run a vac adv with approx 10-12 deg max additional adv and try that on a ported vac source,no vac at idle.

But if that doesnt work good try the vac adv on a full on vacuum source at idle. But make sure you have a vac adv that is fully activated at 2-3 or more iches of vacuum LESS then the your motors idle vac.EX,motor idles @ 10 inches vacuum get vac adv that is fully activated & fully advanced at 6-7 inches of vacuum or as cloase as you can get.

NOTE:Make sure to check your idle vacuum with motor warmed up and in gear if auto trans to get correct reading.

Ensure you have set the inital timing to approx 18 deg btdc with vac adv unhooked & plugged with idle low like 550-600 rpm when setting the initial before trying to get the idle and vacuum adv dialed in. Then re-attach vac adv hose to vac source.

Also if your running a stock dist make sure the total timing doesnt go over 38 deg when running all the additional initial timing of 18 deg thats required for even a mild perf cam that has more duration/overlap then stock cams that normally run 0-8 deg initial. If the total is too high with 18 deg initial you will will have to pull the dist to have the mechanical advance recurved/limited to approx 20 deg max to avoid detonation due to todays crappy low quality low octain fuel . But the new E85 higher octain fuel has potential and some here in T/C are already trying it. I guess we will have to see how the E85 fuel affects the motors and fuel systems over time. I say this because it supposedly has some issues with corrosion over time in the fuel systems due to the Ethenol in it when used in older cars like our snot designed to run on it according to what i have read from oil companies that mfg it.

first i disconnected the vac from the dist. i have a dial type timing lite , reved the engineto 3000 and moved the dist. to 34 with the lite at zero, i checked the vac, i have 15" at 1000 rs off the manifold side of the carb, im running a new edel 600, i also noticed my timings all in by 1800 thanks for all youre help guys i know the only way i can get 34 is to set the initial at 20 btdc/but it pings at half throttle ,could this be because the machanicle adv. comes all in by 1800

does any one know were this cam should idle without a load on the motor

does any one know were this cam should idle without a load on the motor
I have the BB version of that cam (60203)& it idles about 850 no load. Lower if I want but it doesn't like it.

It sounds to me like you have too much initial and that your mechanical advance is coming in a little too fast.

You need to pull the dist to have the mechanical advance recurved to give a full 18-20 deg all in at approx 2800-3k rpms,all in at 1,800 rpms is too early IMHO. Also have them install a vacuum advance that has 10-12 deg additional advance max . The stock vacuum cans can advance 18-24 deg at times which is too much timing when running more intital then stock due to perf cam along with 36-38 deg total but a vac adv is helpfull for street use with your mild perf motor when setup correctly so use.

This will allow you to backoff the intial timing a couple deg to 16-18 deg dtdc and end up with 36-38 deg total @ 3k rpms hopefully stopping the detonation. But the 34 deg total your running is kinda retarded for that cam.

Whats your compression and are you running 93 octain fuel? I am asking this because of the detonation with that cam.

Scott

compression 9.0:1 and sunoco pump gas if i put tighter springs and change the weights will this give me a later totall

I run that cam in a 350/330ho crate motor with a holley 650dp carb and an electric choke with a msd ignition and edelbrock performer rpm intake and 4spd. Mine idles relatively smooth at 750rpm and pulls 13" of vacum. It took a while to tune it but it runs really good now. I started with 10 degrees base timing 32 total nad now run 14base 32 total due to the vortec heads only liking 32 total. With more timing it idled smoother. NOw yo can barely hear the cam. Chekc for the obvious vacum leaks, bad spark plugs etc. I had a plug go bad this spring and couldn't figure it for the life of me. The plug only had 500 mile on it. Good luck.

thanks dave69z,sounds like im right in the ball park, 1000 rpms 15" 16 initial im going to try eliminate the vacuum from the dizzy and see if it still pings,i think my main problem is my converter i believe i was steered wrong from jegs hell its not their money is it? the converter is a 12" 23-26 stall i idle at 1100 no load and in gear at 750 thats 350 rpm drop in gear ,i love the cam smacked it in the ass last nite drove me into the seat and pulled better than the old cam, just wish i went with a converter from a converter co.

You want to START with 34o to 36o total timing. Detonation and/or hard starts will determine the best timing curve. I would guess that your initial should be between 16o and 20o. Having the timing come in as fast as possible is better as long as there is no ping. You need to be safely below detonation.

i can do that, 20 and 34 but if i use vacuum im getting pinging if not no pinging, were do you think i should idle in gear and park cause im getting 400 rpm difference i think i have the wrong converter too

You should get approx 150 rpm drop when in gear. Make sure you are within your carbs. Idle circuit and not running off of the primaries. check to see where your mechanical is curved at or list manufacturer of dist. and bushing colors and spring colors installed. Your converter won't amount to much at this point, so skip it until your engine is running correctly. JN

I've got the same cam in my 350 and it idles at about 850 in Park and 725 in gear. Right after cam break in I had it idling over 1000 but was pulling from above the idle circuit on my Holley 750 vac sec. If you want to test that hook your vacuum gauge to the vacuum port on your metering block on the carb and see if it shows any vacuum at your idle speed. It shouldn't show any. If it does you need to drop your idle.
Oops, just remembered you aren't running a Holley, I bet there is a way to test your carb as well.

Try dropping the idle to 850 and re adjust your timing to 18 degrees BTDC.
I'm running 13lbs of vacuum at 850rpm straight off of the manifold vacuum.

66buickspecial can you tell me what converter youre using i appreciate all the help

I'm running a stock converter. I'm thinking of stepping it up slightly in the near future to a 2200-2400, just because I'm going to be adding an adapter plate between my Chev 350 and BOP TH350 and will have the tranny out. The previous owner missed that step when he swapped in the Chevy motor.

When I had my idle to high I was experiencing a big drop in rpm from Park to Drive like you are. I had my initial timing set at 10 BTDC but the motor REALLY liked it when I followed the suggestion I received on here and went to 18 BTDC.

You want to START with 34o to 36o total timing.

Not with the Vortecs. They seem to like less total timing then other small block heads. He has it right by shooting for 32, but it is coming in too fast. I had the same problem with my ZZ4 which also likes less total timing.
