That's not what you need....I hope and pray my cover is sealed well enough. I couldn't get the pins out, so I drilled the cover and RTV'd the entire thing.
A billet cover would be nice but I don't know of one that exists.

Hey guys, just chiming in. Monday I started into my disassembly. I've started wiring harness also, one sensor and one connection at a time. Its not hard just tidious (should have bought one from mike). Need to ask few questions. Keep in mind that I'm working with pre-86 block inside truck.

first: Will the Vortec distributor work with older pre-86 blocks or do I need to change the distributor gear?

second: Did I hear right? Dale did you start car without flashing memory???

third: Will the Coyles vortec timing chain work without modification, and what gasket did you guys use for oil pan gasket seal??

Pic coming soon thank in advance.

Dale

Dizzy should go right in. Its all basic SBC stuff.

No, you will have to flash the ecm. Even if you get one from a van, it has anti theft that needs taken off. As well, with my setup I'm running very rich. Then whatever options you dont use (egr, rear o2's, gas tank pressure, etc). IIRC Scuzz offered to flash mine, but I had sent it to someone else. After a month its still not back so I bought a new ecm and program myself. Maybe Scuzz will help you, and provide better service then I got from someone else.

I made my own harness as well. Very time consuming. I had time though(then, not now), not alot of cash.

timing chain needs to be single row. Roller will work, just not a double roller.

I don't mind editing out vats, egr, whatever for free if you don't have the software.
I do not do tunes though.
Send it to me with return label and I'll get it back out in a day or two.
The tax business will be upon me soon, and offer will expire after thanksgiving.

I've done both. Mine, I removed the pins in the block. I get a small leak. Justins I drilled out the cover like a stock one and no leak.

This is addressed to all pre-86 small block builders. I ran into a situation with heavy duty vortec timing chain. If you have pre-86 block the cam sprocket will not fit, I guess we'll have to update to new roller cam or vortec cam. I ended up getting the regular timing chain and had no issues with it. Also could not remove timing cover locating pins from block. I drilled vortec timing cover and presto. The oil pan really needs to be dropped if you intend to do this swap with motor inside car. Its not to hard for a truck but car owners be prepared.

That is ingenuity, except I machined mine out of a solid piece of aluminum on a drill press. Took both gaskets, drilled holes, tapped the Linear EGR valve side for bolts. It was a completely square adapter with a bunch of holes drilled in it. I drew it on Autocad to position the valves correctly for the EGR passages to connect. Once I had a working drawing on Autocad, I printed out my templates and started drilling.

Dale

I drew one like that in autocad as well(thats my job), but I could not afford to have it machined, so I made it out of brass pipe n angle iron. Angle iron was free, had over half the pipe ftgs around. Cost me about 15 bux. Its also something "anyone" can do. However, if I was to redo it, Id go with 3/8 pipe instead of 1/2. Will beable to align the holes better.

Dale

Id like to let people know some options that can work with some small effort as I have all this hooked up and not sure if others do.

1. As just discussed, EGR can be made to fit.
2. Anti theft WILL work if you pin it to the LS1 port (blue30??) and change it in the pcm to "PWM" rather then "class2"
3. MAF will fit onto the dual snorkle, 85-89 intake tube, and some rubber couplers from lumber yard. Tight fit, but it fits.
4. Factory 3rd gen coil will work, you just have to relocate it and make your own coil to dizzy wire.(93 lt1 wires wont fit)



?? I have my speedo running thru the ecm. Didnt pay attention to make sure it worked.(was looking for smoke, flames, etc)

Dale

Car is up and running finally. It is still running extremely rich, doesnt like to start or idle. So I will have to learn tuning fast. Also keep getting code 0449(I think thats it) which is the evap emissions system. Any idea what I might have done wrong there? Does ours work the same as trucks/4th gens?

Dale

Found on another forum, the vortec dizzy will NOT fit with the stealth ram intake.

What pins do I hook my clutch switch up to? c1-32 n 34?

wgeous

I have another problem guys. The oil pressure sending unit is broken in block with ez-out inside. I tried to drill out but ez-out is made of harden steel. Mind you, this was done by "professional mechanic", is there any way I can relocate sending unit on block, perhaps a remote filter location? Can 411 operate without sending unit. Again this is a pre-86 block, I've looked by the oil filter but there is nothing there i can tap into.

Also, is there a special o2 sensor to use, I found cheap 4 wire heated sensor online for $27 but no pigtail? What kind of cameras is everyone using to take pics.

Dale

The OPSU may leak if its not plugged off right. I left mine wired inline with fuel pump for safty sakes. It can be bypassed. Then you will also not have a dash gauge. I think some of the older blocks had a way to mount them up by the dizzy?

I belive you have to use vortec/van o2 sensors. Mine were 70 a pop with a "hook up". Gotta love redhead females that work at parts stores

I do photography on the side, so I have low-end-pro grade photo equipment.

Hi guys. Im here to try and help answer questions to the 411 swap for third gens. I have tuned many cars from this forum at our dyno and it has been very nice getting to know everyone. The 411 swap has been a huge success since MKOS, Mike@EFIConnection.com and myself had gotten together to make this happen. There are no down sides to the swap. Tuning the 411 on a third gen has proven to be a very good way to go. If you got any questions, ask away and ill try and answer all that I can.

Dale

I have sent you a PM at efilive forum, can you go read n respond please

Here in California with the smog Nazi's I need a few answers.

One, does the SES light still work the same way?
Two, how do you control the EGR valve?

These are the only things that are keeping me from doing it.

Thanks, Allen

Dale

Not sure if they will require it to meet 02 codes, or actual year car codes since its just a wire swap, not motor swap.

SES light still works. But rather then pulling codes with a paper clip and count light flashes, you need a scanner.

EGr is controlled by the ecm electronically. You will have to fab up your own bracket/mounting

Justin89Formy

Hey Jamy! How the heck do I get ahold of you? I need some tweaks in my tune!

LSRacing

lsracing@live.com That is my personal email address. Send me a message there. Dale, im working on your tune today. I hope to have it done and emailed also today.

Dale

Sweet. I did find some vac leaks like you suggested. So I've been fixing them this holiday weekend. Hopefully between fixing them and your tune this thing should run more like its suppose to.

black_highway

Anyone have any ideas on how to make the cruise control work? I am also particularly interested in using this PCM in a Turbo V6 application. My Typhoon needs a new wiring harness, and I'd love sequential fire with boost control and on the fly tunability in the PCM

d10pins

i have my hp tuner now how do i do a crank relearn anyone know. thanks

Dale

I dont think hp-tuner has a crank relearn? I think thats only efilive, or a dealership thing.
