Engine/Transmission (1994 - 1998) 181's or 191's on 160 with 370's?

[WadePatton]

Is there any big difference? I need to smooth out the low-demand power band.



Engine has 160 pump at 16. 5 timing, #4 plate, 370's, 3K, turbo mods coming.



TIA

181's didn't do much compared to 131's... .



Cut DV's were a huge gain compared to 181's... .



022's were like one step down from the cut DV's... .



All of this was on my 160 pumped truck with 370's, 16. 5_° of timing, etc.

On edit: I typed "161's" above when I meant "131's"... my bad.

 

[WadePatton]

I'm not looking for more power, just want to smooth things out.



Don M says bump the timing to 19°



I think my DV's are 131's.

 

[HoleshotHolset]

You'll fill in the bottom end a little bit with just about any DV upgrade.



It sure ran good with cut DV's...



19° will give you a nice jump in power, but you're into headgaset warning area with that timing. The older trucks aren't known for particularly good headgaskets... .

On a 1995 160 pump I installed 181's in place of the 131's. It smoothed it out in the low RPMs. The SOP horsepower jump wasn't too noticable, but it did pick up a little boost.

does anybody have the part number for 022 dv. thanks

Wade,



looks like the 181 might be the best bang for the buck... I'll get back w/ ya later this week if I score that set of 181's!

Bang for the Buck!



Smoke for the Dollar!



HP for the economically Challenged!

 

[WadePatton]

I got some 181's for $125. Should be here anytime.

 

[Forrest Nearing]

good deal... I still haven't been able to get out to the core supply!

i have some 181's with ~60k miles on them from my old stock pump just sitting there. however, i don't have the dv socket.

Now he tells me.



Maybe someone else can benefit.

 

[98rammer]

sorry bud, missed ya on that. however, i can take a 1/16" drill bit a drill them out... . sell them as Lazer Drilled? Delivery Valves? instant power, especially with the use of a throttle body spacer before the turbo

HELP!

I put the 181's in yesterday. Seems to start/idle better, but the stammer at low boost/low R's is still there.



Will 191's fix it? Or do I need to pull the whole damn pump off and take it in?

 

[bmoeller]

Would it have anything to do with the 3k kit not being adjusted quite right?

 

[WadePatton]

Good question. I put them in per TST instructions and haven't messed with them yet. I was also thinking about the plate contour. I'm moving it back some more next-to about 1/2 way.



Any more input?



In or out with the gubnor springs?

Might want to read this thread.

It's not an idle thing. It's off idle at it's worst after lockup low R's. Smooths out like a baby's behind after 1700, but putting around at 1300-1500 is a rough muther. I demonstrated for Mark today.



With a 5-speed, I'd hardly ever be that low on rev's, but the auto--GRRRR.

timing

I have ran a lot of timing in the 95 that I have before, and it was responsive. However I moved it back to 17. 5 . Never had any problem with a head gasket. Just luck probably. I have heard that this is not good for mileage but that was not the case in my truck. When setting the timing on a 95 be sure to check the cpl number because there is two different settings. lol Jim
