I would bump it back to stock, but you would have more timing on the top end.

yes the shim and spacer keep the stock spring tension to retain stock dynamic timing function. you do not need a longer spring, you could only gain .4mm more travel with a different spring and the time envested in it might not be worth the gain, it could.

and on a turned up truck with stock injectors, 366 spring and an M3 fuel pin, gained 20hp with the spacer installed.
spings are different tenstions i think, non i/c might be weaker.

:tu:Sounds good to me,I will hopefully buy one in a few months.

nborga87 03-09-2010 10:47 PM

hey check out his fuel pins too they're the shit, well worth the money if you don't allready have one

Chevy4bt 03-13-2010 10:11 AM

My pump does not have a KSB. Will the Spacer still work on this pump ok?

it may not have the "ksb" but it should still have something for the dynamic timing advance i imagine. it may be just a cover in place of the ksb. send a PM to Alwaysworking he might be able to iron it out for you :tu:

seandonato73 03-14-2010 01:00 AM

i didn't know any of these trucks came without a ksb....

Chevy4bt 03-15-2010 05:54 AM

My engine is a 4bt not a 6b

seandonato73 03-15-2010 07:55 PM

oh, ok now it makes sence

The_Head 03-22-2010 07:23 AM

I need one of these. My pump got installed and the numbskulls used silicone instead of a gasket. I can't rotate it to advance base timing.


Anymore testimonials? Any pics of it installed?

get a bigger hammer and wack the thing:w2: had to hit mine harder then i wanted to get it to move

The_Head 03-22-2010 10:51 PM

I tried hitting it with a mallet, but didn't wack it too hard. Would rather try this product after I hear more experiences with it.

The_Head 03-29-2010 04:40 PM

I thought this doohickey was the next big thing for us.

orangeamcs 03-30-2010 10:16 AM

put tension on the pump w a strap then whack it wa deadblow hammer. Worked great for me. Now thinking of getting the spacer too. So is a 1/8" timing bump w the spacer to much?

seandonato73 03-31-2010 04:38 PM

yeah if i wasn't so broke right now .....(dam head gasket) i would get one, to the head... yes i would get one if you don't really want to hit the pump with a hammer, same end result, maby a little better

The_Head 03-31-2010 04:41 PM

well, I love the low end with the timing set at stock right now. It's great around town. If this device allows you to keep the low end while advancing the timing at the top.. that would be great.

seandonato73 03-31-2010 08:48 PM

yes i think that is the general concept, it lets the KSB do its job, just with more timing advance

The_Head 04-01-2010 08:11 PM

They are sold out for now. Another production run in 1-2 weeks.:dang:

seandonato73 04-01-2010 09:26 PM

don't worry allwaysworking will get one to ya, he's a great guy

JBradley500 04-03-2010 04:58 PM

can you get too much dynamic timing? im running 1/4" past the mark right now and if i added this part what possible "bad things" could happen?

JBradley500 04-18-2010 06:27 PM

im still interested in this.

The_Head 04-18-2010 06:42 PM

All the regulars here are n00bs and cannot answer you're question, including myself.

I believe Alwaysworking said to set timing at stock when running this spacer, so that is my plan.

JBradley500 04-18-2010 06:48 PM

ok thanks... i asked on another site just now because ive got (very little) money burning a hole in my pocket and i want one of those but i like the added base timing that keeps my boost and smoke down.

Alwaysworking 04-19-2010 12:00 AM

I have 10 instock right now....

The_Head 04-19-2010 02:34 PM

dibs on 1!

The_Head 04-28-2010 10:19 AM

Can you still use the truck for towing with one of these installed? Guess I should of asked before I bought one.

pewder 04-28-2010 01:38 PM

I just got mine on order. Kind of sucks that I'm putting it together with all the tweeks so I really can't compare a before and after:sadnow:.

It should run good though.:itsok:

I did with my truck, no issues, from what i noticed the enigne just stays in the optimum range.

with my truck i was wondering, "will this hurt it" since mine is the test truck and just ran it and listened to the enigne but i did not go easy on it. towing 10k with my foot in it.

The_Head 04-29-2010 11:46 AM

Cool I guess I will be alright then. I only tow about 6K

pewder 05-02-2010 12:55 PM

Well I got my spacer yesterday so I'm gonna get it put in next time I get some work done on the motor. Be nice to see how this thing is gonna run when I get this all done.

The_Head 05-04-2010 09:51 PM

I got mine in. The truck lost 2 psi, and 100* of EGT. The weather was kind of crappy today, so I will have to check again when it's not so windy.

It looks like it will allow me to turn the full power screw up another turn or so, so that's good.

pewder 05-05-2010 12:41 AM

I'm gonna have to figure somethin out then on mine. I for the life of me could not get that damn collar off the fuel screw. If I would have contiued to pull it off then the spot-weld would have just tore a section of the collar and I would have been stuck with a big hunk of weld and collar left. So I'm stumped on that for now.:s:

JBradley500 05-05-2010 05:14 AM

i held the jam nut that was on the fuel screw with a 13mm wrench... just used the 8mm or whatever on the end of the fuel pin, and turned until the jam nut popped the collar off. is that the way you tired too?

pewder 05-05-2010 11:33 AM

No i had the thing out of the pump when I was replacing a few seals and puttin in the goodies and I was just trying to pry it off. Guess I'll have to give your method a try:tu:

how did it feel on power? how much smoke did you lose?

pewder 05-06-2010 12:01 AM

Well guys I think we are still kinda test rats one this little gadget by the sound of those questions. ha ha ha:c:

The_Head 05-06-2010 06:06 PM

I can't really tell you on the power, all I know is EGT's are down a good amount, so I'm going to adjust the full power screw some more.

The_Head 05-08-2010 12:24 AM

I told the shop who reinstalled the pump to turn the power screw back 2 turns when I had the 6 x 14's installed. They didn't do it. So my pump is maxed out. Time to look into having that PDR "hotrod" pump I have installed instead of selling it.

It does seem like it smokes a lot less when warming up in the morning. I don't see how the timing spacer would have an effect at idle, so I dunno.

pewder 05-08-2010 01:16 AM

Well didn't you bump the timing back to stock and then install the spacer? The stock timing would make a difference with the smoke, and still gives you the same advantage as the bump but without the sacrifices that the bump has.
