I've got a spare set of new TR6s at the house I'll throw in it when I get back. Do you think it'll help with the timing on that pill being as high as it is?
i showed half the guys on this thread you started that carbed ls motors like timing(everybody was saying 28 degree's total timing) but no one really asked about plug gap,so i figured i'd throw that out there....msd box's run better on a short gap...i got another trick that will pick you up almost a tenth and a mph thats as easy as 123....
So say a .035 or .030 gap for a non nitroused motor? I had always run my brothers lq9 around 34* without ever having an issue. Everyone always said it was too high.
So what is this other secret that will pick up a tenth?? Running alot of timing in the bottom end? For a while I did that with my 5.3 and it really woke it up.

Bringing this back up
I've been running the 6010 box for a few months now and have been tinkering with it. I've got 34* being brought in at 3200 rpm
Here is the timing and what the rpm it's at. The timing inbetween the RPMs is brought up gradually
0 RPM its got 15*, goes up to 22* at 500 rpm, then 30* at 900 rpm, 31* at 2000 rpm then its at 34* from 3200 til the limiter at 7200.
I'm going to pull the plugs and shorten the gap to .030 like billy said before. This car is only getting a 100 shot for now and I'm pulling 4* from 3000 til the limiter which makes it 30*
Any input guys?

You got a MAP sensor? I'm running 45° at idle (34° @ 600 RPM plus the MAP timing), but I have a big cam and a loose converter. Right now, I'm just trying for a stable idle, after that I'll back it down as much as I can and still keep it idling. I've had to open up my idle air bleeds a bunch, as the car was pig-rich at idle (10.8 AFR) with the idle fuel screws only open 1/4 turn from closed. Good luck on the tight plug gaps, I tried it and fouled my plugs so bad they had to be tossed. Went back to 0.045" and they are OK...

Yeah I've got a GM MAP on it and it's throwing 4* in it until 7 psi then it goes to 0* at 9 psi. I'm not to sure on how to mess with it though.
I put a 50cc pump in the front of the carb, 78 jets in the front and 82s in the back with no power valve and it's got the red cam on the linkage. My setup is a little wilder with the PRC 5.3 heads(shaved .020 with .040 Cometics) and the MS3. Texas Speed said with the pistons I have it should come in around 11.3:1 compression. The converter is a pretty tight 3300 nitrous converter. I need to find someone with a wideband so I can get the AFR set right because I have no idea what it's at.

I've mentioned this in other posts, but I'll repeat it again....the MAP advances and also retards back to normal according to the VACUUM level of the engine. In other words it mostly works (advances) at cruise or at idle (if you have it hooked to unported opening). If you have an MSD 6010, you can adjust the amount of advance and also at what level of VACUUM it advances.
Neat, huh? AT FULL THROTTLE, there is NO MAP advance!! The amount of advance you added on your MAP curve goes to 0. The easiest way to get a picture of this in your mind is to hook up your laptop to your MSD and go for a drive. If you have 32* on your regular curve @ say 2500RPM and 10* on your Map curve....when your CRUISING at 2500 or above you will see 42* on your laptop (click on the 3 dials to maximize them). If you start getting into the throttle pretty heavy or go to full throttle it will drop back and show 32*
Try it!! You might be surprised! Ron

Don't mean to hijack but I am going to start it up real soon. And I want to know what timing is safe to start it up and move it around (not for the track yet). My set up is a 383 ls1 ms4 cam twin turbos, 12.5 compression, 10psi. 2 bar map sensor, demon 850 carb. Any imput will help!
i have a heads and cam ls1. I jetted down my holley and took 2* initial timing out of it. runs great now.
i run 15* initial timing from 0-1000 rpm then it steadily increases to 29* total at 3000 rpm.

if you have problems starting ensure you have a very large battery connected and the engine spins over quite quickly. my new engine was very tight, and when cranking the msd box couldnt see a fast enought trigger signal from the crank signal. i ended up sticking two batteries in series at 24v direct to the starter only after 3 nights of trying and it fired within 3 seconds when turning fast enough!
after it had bedded in for a few minutes it then turned over on 12v no problem and fired first time every time. your battery and starter need to be spot on on a new build!
