ComicArtist Posted April 19, 2011 Share Posted April 19, 2011 Swapping an '81 L28ET into my '78. I have all the parts that came with the motor, including harness, all the sensors, vacuum stuff, ect. However, the CAS bracket was disconnected from the block where it bolts up. Just wondering if I can bolt it back onto there or if I need to turn the crank to TDC or anything before I put it back on. Does it require any timing at all? Thank you! Also, the spark plug wires are all disconnected. If anyone has a diagram or picture of which wires go to which plug from the distributor, I'd appreciate it greatly. Thanks! Ben Quote Link to comment Share on other sites More sharing options...
rayaapp2 Posted April 20, 2011 Share Posted April 20, 2011 Highly recommend not messing with the stock 81 CAS. The 82 and 83 CAS can easily be supplemented in its place. To answer your question though you can simply bolt the bracket and CAS back in place. Leave the lock nut loose, attach your timing device, and adjust the adjuster nut until you get the desired timing. You do not have to rotate the engine to TDC for this install.

ComicArtist Posted April 20, 2011 Author Share Posted April 20, 2011 Okay cool. I'll probably just continue to use the '81 CAS for the time being. I've never timed a CAS before; is there any particular way to do it or is it just like the distributor? And what does it need to be timed to?

HowlerMonkey Posted April 21, 2011 Share Posted April 21, 2011 Make sure the sensor isn't touching the "wheel" that triggers it. Removing the fan makes it easier and I used a feeler gauge but don't remember thickness. Quote Link to comment Share on other sites More sharing options...
