Voodoo Cam. I finally got my timing tape on it yesterday and got to look at it quickly before it flew off! The problem I am having is that the car runs perfect set at 20 initial and about high 40's full. Everything I am reading says this is too much but if I back it down to 12-14 and about high 30's it doesn't run as good. Any ideas??? 1968 Roadrunner 383 auto .060 KB 400 domed pistons, Stealth heads, Torker intake, Holley 830, Lunati Voodoo cam 276/284, .513/.533, TCI 3500, 3.91 gears, all ARP fasteners,

I have to get my info out from the distributor and figure out how to change it. 1968 Roadrunner 383 auto .060 KB 400 domed pistons, Stealth heads, Torker intake, Holley 830, Lunati Voodoo cam 276/284, .513/.533, TCI 3500, 3.91 gears, all ARP fasteners,

When I went to the pure stock drags in 06 some very well versed guys from the detroit area told me to bump the full advance timing on my 69 383 to 42 degrees , I bumped it to 40 , car did pick up ...

I hesitated to say 40-42 for safety reasons but I have a friends 383 with KB400 pistons, ebrock heads, and Engle Hyd. cam set at 42. It's what it likes.

Pay special attention to the overlap of the tape. It will never come off and you will never wonder if your dial back light is working properly. I have seen so many flakey dialback lights that I only use my old(really old) Sears Penske non dialback light. Besides I don't have enough hands to rev the engine, hold the light and turn the dial all at the same time. In theory, there is no difference between theory and practice. In practice, there is.

What I did was make sure the balancer was clean then I wrapped it around the balancer, now here is what I did that most guys don't think of doing and this is why they fly off. Super glue both ends to the balance or to each end of the tape. And for good measure put the glue on the balancer at different places before wrapping the tape around balancer. After 2 1/2 years it is still on!!

Any ideas??? yes 36-38 total (vac unhooked/plugged) is a tried & true BB total but 383's esp low comp 383's are an exception and alot of reports of doing better w it in the 40's & KISS in your case it runs better & if no ping you are fine & no reason to retard to 36-38 but I would go about it in order; initial w vac ga method then slots to let it get in the 40's then springs then (re) hook vac adv & work w it (if using it) and I would check if timing marks are exactly TDC. not likely but cant assume anything live every 24 hour block of time like it's your last day on earth

For safety reasons (you can have knock but ont hear it) I run at 38 total but when I was at 8,7:1 before rebuild it liked 45 total (no vacuum). Last edited by willard; 07/26/11 03:30 AM.
