Re: PO has me PO'd
Nice improvements to the engine, Dale. Ill look into the egr mod. Found the ac delco map senser at tpi parts.net
Picked up the harness from my coil to the distri. there too I see a boss on the plenum at the location you indicated, heres the mystery bracket. Where did you find your map bracket, still searching the net http://farm9.staticflickr.com/8480/8...be72edcb_c.jpg 20121116_111430 by jarosaj, on Flickr |
Re: PO has me PO'd
Ive never seen a bracket like that before.
You "could" drill n tap that, but your taking a risk of a vac leak. I would look at mounting it else where, like maybe on the same bracket as the coil? You depend on how long your wires are for it. |

Re: PO has me PO'd
I was saying to mount both away from the motor on a custom bracket. But the coil is self grounding, so it needs to be on metal.

Re: PO has me PO'd
Oh, Ive "tuned" it. But I have no clue wtf I am doing. I use Efilive to tune.
Fixing to send you pm about parts. |

Re: PO has me PO'd
Sorry but I won't be any help as far as tuning. I haven't got to that point yet. I'm rather aprehensive about it as I don't know what I'm doing either. I want to learn but I have a feeling the curve is going to be big.
Have you tried the Efilive forum? How about the GM Performance forum? Sorry for the hijack jaros44sr. Quote:

gm forum, uhh.... I was at one other, not sure thats it. One problem is I am on an automatic tune, and I'm manual. The other, I may have figured out about 5 years later. But "fixing" it I cant figure out how to. Its not a tune issue, its a physical issue. |
Re: PO has me PO'd
This is the other forum I was talking about....
http://www.pacificp.com/forum/index.php Those guys mainly work with GMT400 and GMT800 trucks, but there are some smart guys there when it comes to EFI tuning. I believe some of the guys there are the ones that came up with the 411 swap. I know Lextech is a member there, and he seems to be the go to guy for the details on the 411 swap. I don't know if I can help with the physical issue, but I would be willing to try. You can send me a PM if you like so we don't derail this thread too much. Quote:

Re: PO has me PO'd
Had a ahhh ha moment, found an nos hose for the fuel regulator, but it didnt fit right. So, after letting it snap back into its natural position, isaw that i had to clock the fuel regulator
Also, got the pcv barb installed on the intake (permatex), that system seems to be right, just have to bore a hole in the vc for the inlet air Thanks dale Getting ready to drill hole in firewall for new fast xfi wiring harness Map sensor seems to be mounted on plenum above fuel regulator, gotta wait to buy map sensor to figure out final mount. Depending on size of outlet on map, i have one more port along side of the port for regulator. Large port on the right rear of plenum will be used for brake booster Richard 2717....iwas wondering if you could duplicate the font on this decal, just wider and taller http://farm9.staticflickr.com/8058/8...b36e99af_c.jpg 20121124_092120 by jarosaj, on Flickr http://farm9.staticflickr.com/8479/8...230c16f7_c.jpg 20121124_091437 by jarosaj, on Flickr |
Re: PO has me PO'd
Finally got the FAST dual sync distri., now i can use sequential injector timing. Motor will be happier...
Goota check on the drive gear compatiblity http://farm9.staticflickr.com/8337/8...7fe87f3f_c.jpg 20121126_133954 by jarosaj, on Flickr |
Re: PO has me PO'd
Jim,

Lenght of letters on decal is 6 1/2" |
Re: PO has me PO'd

Re: PO has me PO'd
That setup looks awesome! Hit it with some bead media to give a nice finish and your set!

Are you still doing powder coat...glad ya got back to working on your truck, still one of my favs. Dusty, enjoying the hell outta it. Finally figured out the lay of the engine harness. Map, air and h2o will go down the drivers side. TPS, IAC, wiil run down the other valve cover covers, should keep it symetrical in size and away from noise from power cables. Crank, tbd, as im not sure where that goes Maybe ill get to drill the hole this weekend, and start pulling cable Still have to buy ignition box, and fuel pump, filter, injectors, crank trigger, so i am getting close to the end of the spendy things Had plans to work on it over the holiday, but jeremy was sick for 7 days. What a condition that was for the wifey and i. Spent the whole time between the bathroom, bedroom, an laundry room. Oh well, joys of parenthood with a special son! Hes a tough man.... |
Re: PO has me PO'd
Yes still doing a little of everything, including coating. I am hoping to be able to really get some work done this winter. Jr has hockey till the end of january then put the hammer down.

Re: PO has me PO'd
Well got a couple hours to play with the truck. Bored the hole in the firewall, differant kinda holesaw, had grit glued to it, instead of teeth. Worked well, without a lot of grab, saved my wrist....
Finally became the po that cut a hole in the oem firewall. Oh well, some time ya just got to break some eggs to make an omelette Layed out harness, seems like it will fit well, but will probably have to shorten some of the legs. Talked to Darin at M&H, said he would sell me the fabric loom matrl., will kinda fit the 70's look of the engine bay, as opposed to the 90's look of thesplit plastic loom Also, will move the factory engine harness over to the drivers side, keeping the power wires AWAY from the sensor leads One of these days, i will clean up the last of the farmers mud on the firewall. Dunno, kinda became attached to it. Does come off nicely with waterless hand soap ttp://www.flickr.com/photos/87678561@N08/8229406985/]http://farm9.staticflickr.com/8198/8...78e968c6_c.jpg[/url] 20121129_121119 by jarosaj, on Flickr url=http://www.flickr.com/photos/87678561@N08/8229407099/]http://farm9.staticflickr.com/8204/8...ab37bb25_c.jpg[/url] 20121129_121204 by jarosaj, on Flickr |

Re: PO has me PO'd
Thanks Cap., the family is all excited...my sons comment to me was, Dad, can you teach the girls how to rebuild cars like you taught me....
Just found out that i have to use a crank trigger, thats what the crank lead was for, oh well add that to the list Plans changed, all the leads will run down the left side of the motor. Its not too bulky Hey dale 99, do you know what the sensor does in post 1935, its the one to the left of the temp. unit, brass piece goes into the water passage. I dont have any wires going to it.... |
Re: PO has me PO'd
Located and ran my IAC, TPS, COOLANT, wires

Re: PO has me PO'd
I didn't inquire about them, but I knew there had to be some reason those FAST cam-sync distributors were so much less than a MSD. I was kind of thinking they may need a crank trigger.

Had some time to go back and work on the pcv, still have to install oem diffuser in the valve cover

Re: PO has me PO'd

Carbs are easy, but i couldnt make them work with remote start, or steep angles off road. Maybe by adjusting my fuel pressure down, but that didnt solve the romote start problem Plus, the cool factor....someday englese eight stack Thanks to guys like dale, ive gotten past the humps Wouldve been easier without the vortec heads, and stock valve covers could save some work....although problems with the oem distri. would still have to be addressed |
Re: PO has me PO'd
Finally got the ECU installed where i want it, just some fine tuning. Final plans are to drill and tap(1/4-28) the heater control panel mounting tabs
Still have to change angle of the mount a bit, plus add some sorta support to the heater box. Probably a bolt, spacer, and a nutsert Power cable is run to the battery http://farm9.staticflickr.com/8478/8...cdb03785_c.jpg 20121209_113209 by jarosaj, on Flickr |
