Thats the kink from me ripping it out from under the shroud to take the pic, it straightens out once under the shroud, see bottom pic on last page.

I have made some progress since my last installments. I received the correct SPI tank this week and figured out what to do with the trans fitting for the 4L80E. I went out and bought a $8 Spectre 3/8" fuel fitting and had it welded to the factory fitting after it was milled down a bit, It will work great in the confines of the trans tunnel.



I will be starting the car next weekend, I have everything and just need a few hours.

It's alive! We fired it off tonight for the first time, it started up with a stock LQ4 tune but was dumping fuel from the 42# injectors, I uploaded a tune from a Magnacharged/mild cammed 04 GTO and it works but needs to relearn. After 1 year and 8 months here you go guys!

VERY NICE. I might consider building something like this after I get out of the lawn mower racing scene.

Nice job. That 2 LS A-Bodies in one week. I just fired mine. I would prefer the Maggie one mine though

Well all in all it was a good weekend. It fired up but was throwing the p0343 cam sensor code of death. After a few hours on tech and losing sleep over the possibility of having to change cams, I trouble shot it down to an open in the harness. I piggy backed the connector and it fired up but still would not idle. I did some work in HP tuners and have since been able to get it to idle down to about 750 rpms. Throttle response is ridiculous. I have a few other issues, IAC temps where around 111* just idling after startup (65* in the shop) and the tach does not work. There is some clean up to do now and I need to re-route fuel lines and get the harness figured out.

This is an awesome build! It sounds like you' ve really done your homework on this project! I' d love to do something similar, like perhaps putting an LSX in my fox body, but I dunno. I think I' m too stupid to pull off all the work you' ve put into this project.

If you need any help with the calibration let me know, we would be more than happy to help you out. Nice work!

My main issue right now is the thought in my head that something is wrong electrically. I have no O2 sensors in the car and do not get a SES light or code, the motor rolls over for about 8 seconds then stumbles to life, no tach output from pin 10 (RPM does read off crank sensor to the scanner, just not off the cam sensor to the gauge)

- The O2 problem I believe is because the ECM has not "called upon" the sensors yet, because it has not ran in closed loop yet. I need verification that the fault will trip after the ECM tries to use them for closed loop, vs. enabling the fault right from startup. Any insight?

- I think the extended cranking may be a tune issue

- The tach I am fairly confident that it is wired correctly, I have briefly looked into it and found no faults. I do not know why this would not work unless going back to my O2 sensor issue there is a problem in the SES/fault enable portion of the computer not showing a cam pos. problem. But this would not explain the P0343 issue I already resolved, it activated the SES and displayed the fault. I verified in the tune that all these DTC's are enabled.

Great build. I admit I have myself thought about a ls1 in my 67. The money I spent getting 500 reliable hp out of my bbo would have built a 1000hp ls1. A year after I built my combo edelbrock came out with there heads now they even have a vic jr

B18CYA: Sounds like you got a pretty healthy BBO there. I was in process of collecting parts for a 388" SBO stroker when i said F'it and started this.

I had to replace the front seal due to a pretty serious oil leak, I should have listened to my buddy who told me to replace it when we did the cam. The Magnacharger crank pin kit was a PITA to get back lined up while putting the balancer on, it finally went on after cooking the balancer in the oven at 350* for 20 minutes, I just had enough time to line everything up before it tightened up. I have troubleshot my no tach output down to the computer. I am going to take the ECM in to work, apply power and a false cam signal waveform and check the tach output pin to be 100% confident. I'm glad its not the sensor, I do not want to pull the blower off to swap it. I have lower oil pressure than I would like, ~37psi at cold idle. I believe the pump might be cavitating at the pickup o-ring, so I'm forced with the decision to remove the engine or not to look into this. I think the pump should be making much more pressure than 37 psi, its a Katech ported LS6 with 5w-30 mineral oil, I was planning on 55+ psi. The needle moves slightly to around 43ish when it revs.

My driveshaft parts are on order and when they get there I am measuring and sending the dimensions to Weller Truck Parts in Grand Rapids MI. They are hooking me up with a custom shaft for the right price. I am using 1350 solid body u-joints and a Denny's driveshafts custom 4L80E slip yoke.

HOUSTON WE HAVE A TACH!

The addition of 4 volts to the tach line did the trick. I set the tach resolution in HP Tuners to 3 and 3, now shes dead on. Another issue tackled.

The good guys over at Magnacharger are writing me a tune and hopefully I will have it tomorrow.

Nice!! Is it idling better now and how's the oil presure?

ryanvv355

iTrader: (17)

It idles better than it did initialy but still needs some work. The tune the Magnacharger folks wrote me I have not loaded yet so I do not know if it will help or not. They are very cooperative and helpful so im sure they will iron it out for me if it doesnt.

The oil pressure I am not too worried about right now, it is still cold out and I am running thinner oil so I am going to change to 10w-40 full synthetic and see what happens, as long as it stays where its at I am going to run it.

I changed my mind from Hooker Aerochambers to 12" Dynomax bullets, I cant see spending $160 on mufflers right now.

My driveshaft was built today in Michigan and will be on its way down here to NM tomorrow, hopefully i will be driving it in 2 weeks
