i just dont get it
as alot of you know by reading my posts, i just installed a voodoo cam in my 350 chevy part number 60103.i was talking to a guy who has the same cam,but in a big block,and can idle at 850 with no load. i tried it and it really lopes but when i put it in gear it only idles at550 and barely runs. im thinking its my converter i bought from jegs, its one of theirs,12" 23-26 stall does it sound like i need a different converter?GLENN
you can do it if you know how it works

well 350 and 454 cubes first off.The cam ,if I can remember right will tighten things up with more cubes.The same cam from the 350 will "smooth out" slightly in a big block.It could also be your conv.,but you can't judge by the same cam in a big block.Last edited by BigTruckDriver; 09-28-2006 at 07:29 PM.

i think mines converter related the carbs brand new and i didnt have this problem until i changed the cam , I THINK I SHOULD HAVE WENT WITH A CONVERTER FROM A CONVERTER MANUFACTURERGLENN

Getting the correct conv. for your cam is a big plus!

True converter can be playing into it (perhaps in large part), but don't discount the carb just because it used to work fine. A radical cam will lean out the mix... try to readjust your idle circuit for max vacuum and it might just idle better.

In my opinion, I see two problems here:
1. faulty converter
2. too much cam for the static compression ratio
I cautioned you not to use too much cam back in this thread:

Your 60103 has a 0.050" duration of 227/233, way too much for a 9:1 motor. Lunati recommends a 2,400 stall converter.PLANET EARTH, INSANE ASYLUM FOR THE UNIVERSE.

let me refrase that. Im not trying to be smart, i appreciate youre advise techinspector,and youre knowladge. i should have known better when i ordered a 12 inch converter
i spoke with a genlemen from lunati who is very knolageable it might have been this harold that every one talks about he spoke with me for about a half hour on how to get this cam to work for me for my intended use, being that i was a little low on compression we had to figure a way to increase cylinder pressure ,by overlap. the cam runs real strong from 25 to 6000 with 15 inches vacuum at 750 , the problem im having is trying to get it to idle in gear at a low rpm and to much advance at half throttle, i will figure it out , and i realize that a small cube motor is going to make the cam sound bigger and act that way, if i turn the idle to 1100 and in gear at 750 i have no problem but you cant hear the cam no more, and as far as the pinging ... ill disconect the vacuum from the dist. all together and see what happens,ill also have to replace the springs and weights for my advance, the carb is adjusted for max idle capability by using a vac gauge, i was just wondering if any one used this cam and were they idled , i still beleive i was misled by jegs saying the converter would workGLENN

Keep us updated.Also I had a hard time getting a good answer from jegs,summit,and the cam company for the correct converter.Theres a lot of variables in getting the correct one for your application.

If you guys want the straight scoop on converters, put this address and phone number in your favorites to refer to later. Talk with Bob Hughes or Paul and they will cut through the crap to help you. Bob is a great guy and knows how to treat his customers. He always used to have a big feed on for the guys at the races. http://www.hughesperformance.com/contact.htmlPLANET EARTH, INSANE ASYLUM FOR THE UNIVERSE.

i have to tell all of you, i wrote a e mail to jegs told them i was dissapointed in their coice of coverter for me.. what happened was i asked about jegs 10" converter 27-3000 stall and the tech said i would be better off with their 12" 22-2500 stall .i purchased the 12" and i feel its not the right one ,the car drops in idle to far and if you turn the idle up it pushes through red lites.
i recieved a reply from someone at jegs thaat told me thats the choice he would have made also, but pull the converter out of the car and thell replace it with what ever i want...pretty cool, i wasnt expecting that so in the mean time i called jegs and spoke with a tech that told me i need the 10" 27-3000 converter[the one i
wanted from the begining ]
ps any thing i want?.....give me a full 871 blown alcohol injected big block crate motorGLENN
