Popular Post chris r Posted June 13, 2020 Author Popular Post Share Posted June 13, 2020 So the car parts gods smiled on me today. Spotted a falcon and thought it looked it had a carb. I wandered over to try and figure out vacuum lines. That's not a carb... Yoink 10 2 Quote Link to comment Share on other sites More sharing options...
Popular Post chris r Posted June 13, 2020 Author Popular Post Share Posted June 13, 2020 Pulled the points dizzy and gave the replacement a clean Drilled and tapped some holes for the hei module. I had some too long screws so trimmed them to suit Tapped out a existing hole to m4 for the earth Consulted my handy parts manual for the timing order and figured it ht leads. Chucked a new set of plugs at it while I was in there. I've put a relay in so ill actually get all the volts to the coil/module. It'll be triggered by the original blasted feed. This can all be removed and put back to stock of needed. As I was tidying everything up I realised I'd forgotten to connect the bypass wire to the module so it doesn't do its own advance. Will fix that tomorrow 13 Quote Link to comment Share on other sites More sharing options...
Popular Post chris r Posted June 14, 2020 Author Popular Post Share Posted June 14, 2020 56k warning Popped over to my uncles today and we had a play with his plasma cutter, Did some test runs on scrap steel and they all matched up Played Tetris one the scrap metal we dig out of a bin Drew up a air cleaner base.got it slightly wrong but it turned out perfect for the tbi Grabbed another bit of all and did the rest of the plates Everything cut out and pilot holes drilled I'll finish filing and tidy the rest later 12 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 14, 2020 Author Share Posted June 14, 2020 So I could have brought a 90 dollar adapter but why not send 5 hrs in the shed to make it yourself 7 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 14, 2020 Author Share Posted June 14, 2020 We did tweak the base plate or Holley pattern template to suit the manifold better. Here's the other vid I took of it being cut 9 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 15, 2020 Author Share Posted June 15, 2020 Here's a closeup and brief overview of how I connected the gm module @dr.wylde So the stock two wires from the pickup Coil on the dizzy go to the two terminals on the back of the hei module. I recrimped these to suit the different terminals. The module I have has letters stamped above the plugs to help identify the pins The two wire plug has the 12v feed (+) on the left and coil negative (c) on the right side if your looking into the plug. The 4 pin plug is ground on the left(g) . Second in is your timing bypass(b) . I've (forgotten to) connect this to the 12v feed. In theory this will stop the module from using its internal advance. Third from left on the 4 pin is tach (r) and the pin on the right(3) is the timing control terminal or signal from the ecu. I have had it working on the bench and sparking but don't know how the timing delay etc will work. The plugs are easy enough to get. 20 ish new or you can go raid a commodore for them. 4 pin is the idle motor plug and two was the air temp from memory (not 100% though) I got my modules from aliexpress ages ago for about $10 each. I got two because cheap and aliexpress. Time will tell how reliable they are. https://m.aliexpress.com/item/4000704459881.html?pid=808_0000_0101&spm=a2g0n.search-amp.list.4000704459881&aff_trace_key=&aff_platform=msite&m_page_id=5549amp-Gr-zdaciz7oP1KsplQwYbA1592216178262&browser_id=1ffe9167cb2047239b7881fe1a1808ab&is_c=Y 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 19, 2020 Author Share Posted June 19, 2020 Replaced the heater hoses. Ones were well rotten Had a play with the 3.8 m8 coil pack I got off @tortron Gm quality.... That makes it super easy for me. I'll strip out the stock shit and for the bosch ignitor in under the coil. Should be a neat enough end result 6 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 21, 2020 Author Share Posted June 21, 2020 I don't believe in imperial so re tapped the manifold Chopping board carb spacer I tapped the adapter plate but didn't have any bolts long enough. Popped into bunnings for a bit of threaded rod and some loctite All bolted together 8 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 21, 2020 Author Share Posted June 21, 2020 Drilled some holes in the air cleaner base and made a bracket to screw the cover on Hopefully it'll actually clear the bonnet.. That's future Chris' problem 7 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 21, 2020 Author Share Posted June 21, 2020 Wrapped the exhaust as i didn't want it to cook the alternator or starter Blocked off a couple of vacuum hoses and rangid up a fuel supply I've got 11ty vacuum leaks but it's running pretty well considering. I need to replace the engine mounts too as they are super soft. 8 Quote Link to comment Share on other sites More sharing options...

Popular Post chris r Posted June 23, 2020 Author Popular Post Share Posted June 23, 2020 @piazzanoob popped over and gave me a hand refitting the manifolds so they actually seal. Bit of rtv and a extra set of hands did the trick l! It was still running like a bag of dicks until we figured out which one of the three vacuum ports needed to be connected.... 12 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 23, 2020 Author Share Posted June 23, 2020 Will grab some vacuum, fuel, and brake booster hose to replace what's Missing/old/fucked. Went to replace the hoses and the new ones are way to short which is a bit of a cunt. Supercheap took 6 weeks to send them so they better bloody take them back. The drivers flare nut was tight/stripped af so it'll be getting replaced soon 2 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 29, 2020 Author Share Posted June 29, 2020 Tamed some birds and welded the mufflers on It idles okay but is super rich and backfires Will have a yarn with weber specs at some point and get a idea on what jets I need Yeah she's rich I need to weld up some hangers and wack another flange in so it's easier to remove and refit and weld up a tail pipe 6 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 30, 2020 Author Share Posted June 30, 2020 So I'm a retard and didn't connect the fuel to the inlet so the bowl was dry, it was connected to a vac port and sucking fuel in through the vac hose on the inlet lol. it runs less badly now, rill rev out if gently open the throttle but if you give it a stab it backfires. will need to re figure out the vacuum lines and get a wideband (and get into the injection as thats easier for me to understand) and see if it is lean or rich on accel 3 1 Quote Link to comment Share on other sites More sharing options...
chris r Posted June 30, 2020 Author Share Posted June 30, 2020 From what I can gather from various forums that are still hosted and pics that still work the vac hoses should be connected like this? I tested the bi metallic strip for the choke and that's fucked/not working so I'll figure out how to barry it onto the old choke cable, or just remove the butterflies or cable tie it open @The Bronze I found your old posts with vacuum lines but all pics are dead. Could I pop over and have a squizz at yours one day Quote Link to comment Share on other sites More sharing options...
The Bronze Posted June 30, 2020 Share Posted June 30, 2020 Mine is down at Lyndale Motors getting sorted because i was having a mare. I got a guy off FB to send me some pics that kinda help. I can forward them to you. 1 Quote Link to comment Share on other sites More sharing options...

Mega friendly helpful dude. I ordered a set of mounts so the engine might actually stay contained. Ordered at lunch and they were delivered by the end of the day. Pic of mounts as text is boring Cdl auto parts also have jets to suit the 34adm and were nice and helpful on the phone unlike a certain specialist. Once I figure out what jets I need I'll be ordering off them 5 Quote Link to comment Share on other sites More sharing options...
