Way TOO Lean??
Hi,
Newbie here.
Never been on a forum before.
Not sure if I am doing the right way.
I apologize if incorrect procedure.
I have installed 32002 on 1696 Firebird. Built 400, eldelbrock ported heads, Hydraulic roller cam 230 intake 236 exhaust Lobe separation 112. Lift with 1.65 rockers Intake 561 exhaust 573. 9.5:1 compression. Edelebrock Performer RPM intake.
Initially started with RTR MSD distributor. Had fuel dumping issues due to MSD redline display. Solved that.
Decided to use timing control and changed distributor to MSD pro-billet.
Locked out advance and finally gave up after many, many hours of trying to stop RPM noise. Entire engine looked like a pan of JIFFY-POP. Shielded wires with grounds, etc.
Ok so now I have intsalled MSD RTR 8528 after again having problems I have had RPM on hand held show 58,880 RPM and 360 rpm at random.
This has caused a fuel dump.
This may or not be a problem, however it has shown above numbers exactly a few times.
After all this I finally have engine running and decided to raise rpm to clean plugs after all the fuel dumps.
When held at constant 4000 rpm for about 1-2 minutes, I noticed my headers were glowing.
Am I running TOO lean, is this something that will correct itself.
Not sure what is going on and don't want to destroy my engine.
This is the second build as previous build was done incorrectly(problem with thrust bearing) after 6 hours of run time.
I am NOT able to drive car as it is waiting for paint and is NOT currently street legal due to no headlights, tail lights bumpers,etc.
trying to sort all I can before I have it painted.
Paint has been scheduled (today!!) for Tuesday 5/21
Any help would be appreciated.
Thank you
Glowing headers is a timing issue. Double check your base timing.
As for your electrical issues. Can you post some pics of your wiring?
Base timing is currently @ 18*. Seemed to be where it appears to be happy.
This is same timing before EFI. I have driven car before taking apart for paint about 3k miles, highway and streets.
Haven't looked at headers, but after glowing, headers have different color.
As far as wiring, I removed all tinfoil and other shielding after changing back to RTR distributor.
Currently can't take pictures as car is at body shop.
I did notice that there was a leak on TB where side plate bolts on. Discovered that there is a machining defect in side plate,
also injectors leaking AFTER engine turned off.
Waiting on new injectors & side plate to be delivered.
Will follow up after new parts arrive and see if anything changes.
