Modifying a TB setup with larger injectors???
Is there a way that a stock throttle body on a 1994 GMC K1500 350 can be
modified with larger injectors? A bit more fuel with a ram air setup and headers should equate to a bit more snort, right? Any sources for getting parts of this nature? Looking for opinions and any advice that might be helpful. Thanks. Andy |

Gary is absolutely correct, tweak the rail pressure first (9-13psi),
then read these articles: http://chevyhiperformance.com/techarticles/148_0307_tbi http://www.goingfaster.com/spo/modthel03.html -- Mad-Dog '79 Chevy K-10 Slightly modified http://mad-dog16.tripod.com -- "TranSurgeon" > wrote in message news:YNbYc.108947$TI1.75664@attbi_s52... > > "AndyW" > wrote in message > ... > > Is there a way that a stock throttle body on a 1994 GMC K1500 350 can be > > modified with larger injectors?

Thanks to all for the replies and suggestions. I'm looking at the budget to
try out some of this stuff. Andy "AndyW" > wrote in message ... > Is there a way that a stock throttle body on a 1994 GMC K1500 350 can be > modified with larger injectors?

Seems a little pricy for what you get though. Also, I run a MSD adjustable timing module. Its a slick deal that gives you a knob on the dash, allowing you to adjust the timing on the fly. When you choose to, you can run premium fuel, bump the timing up a little, and feel it pull noticably better. Conversely, if you get a tank of bad gas, or are towing, you retard the timing so it doesn't ping on you. Later, B. |

Brian:
How does this MSD box work/mount? For my vehicle below, what special modifications would I need? I went to this link and there's two different types of units. Which would I need? http://store.wpsracing.com/msdadtimcon.html Appreciate the education.

Hey Andy,
Without running out to the truck to be sure, I believe it is this one. http://www.jegs.com/cgi-bin/ncommerc...90&prmenbr=361 #121-8683 I can double check if you like, of just give Jegs a call. It was easy to install, you tap into a couple wires at the coil, power and ground the box, and run the wire and knob to the dash. It is CA smog legal too, or at least was a few years ago. I'll double check the info if you like, lemme' know. Brian. "AndyW" > wrote in message ... > Brian: > > How does this MSD box work/mount?

Andy,
I checked under the hood, and yes, it is a MSD 8683. B.

Brian:
So, from what I read on this module, an MSD 6-Series, SCI, 7-, 8- or 10-Series Ignition Control.is used in conjuction with it, right? Is this worth the effort and money? The way your post reads, you're just using the timing module; what kind of results are you getting?
