It could be, probably does. I reused the carb base gasket, forgot to check for a leak or retighten the bolts. I want to concentrate on the EFI swap.

Well as always, nothing is truly universal. My intake has EV6 injectors and the Terminator X Max universal comes with Bosch style injector harness, so adapters will be needed.
Finally the weather improved, I wasn't working in my shop in -25C highs last weekend plus my Wife was off. This weekend she is working nights, so plenty of time. First I had to address the TH350 leak. I know an old GM trans leaking, shocking. I thought it might be the pan or pump seal. Nope the speedo seal. So I grabbed an O ring out of the TH4L60E seal kit in first and found the little push in seal in a drawer, looks exactly like seals they sell online for the TH350 bullets. Slowed it down from a slow drip to barely wet after sitting overnight. I brought the motor to 0 and the rotor to #1. I soldered the wires together on the Accel dual sync, not sure why they don't combine them together. They plug into each other and a not included and no longer available adapter harness. Cutlassefi said just combine them together. Basically 12 volt red, white signal and black ground. Two additional black with rings to ground. I mounted the Mallory Hyfire box and MSD noise capacitor and Accel Super Stock coil. The injector adapters fit nicely. The IAC fits and clicks, TPS fits but doesn't click. I hooked up the power brake booster to a manifold nipple, modulator and PCV also to manifold nipples. I hooked up the rear EFI rail crossover and the the 30 micron cleanable 8AN filter. I also changed just the oil filter, still some glitter but less than the last time. No doubt some didn't come out. I plan on just running this oil to make sure the EFI works properly then will change the oil and filter again with VR1 10W30 and a Wix 51258. I ordered a different oil filter cutter, my All Star Performance one deserves no stars, works like crap. The Motomaster OE Plus are well made oil filters, really hard to cut through. A small amount glitter from my Daughter's 2017 Hyundai Eltranta. She way overfilled the oil. Uses oil and the dipstick is really hard to read. I bought a Protec by Wix, $2 cheaper. I see 5000 mile claims, said 10,000 mile on the box. I want see if it is built as well as the Wix/Napa Gold 51258, a variation of that part number. I put it on and filled it with the last of the old SL rated 1100 Zinc and 1200 Phos 10W30 Quaker State Defy 10W30 I have probably had for 5 years. I soaked down the tank straps. I just need to change the hose at the sender where the new Holley pump drops, one spot near the front, where it connects to mechanical fuel pump. Pretty sure the mechanical pump was dying no fuel in the line or the carb when I took them off.

I basically spent the weekend getting the fuel system ready for SEFI. I added the 30 micron fuel filter with EFI rated braided hose with twist together 8 AN fittings and EFI clamps at the motor. I also replaced the one small piece just behind the motor with braided hose and EFI clamps. I dropped the fuel tank. I painted underneath it and I picked up a pail of Fluid Film on 1/2 price. I didn't realize it was not fluid, concentrated like nasty butter scotch pudding. I put it on the tank straps, anti seize on the tank bolts. I covered the top with some paint the 3M sound deadner. I got it cheap on sale, can see why, it gets brittle quickly. Suprised 3M stuff is usually top of the line. To get the O ring on the Holley drop in fuel pump assembly, it needed split in half. Also needed to split it, to put it in. I lengthened the wire for the gauge so the fuel pump power reaches as far as possible. I cut more braided hose, added another 8AN twist together fitting100 mimcronfuel filter just after the pump outlet connected with Dorman EFI clamps. I doubled the clamps at every connection. I just need another 8AN fitting and filter bracket and it is plumbed. I also had to add an 3/8" NPT to 1/4" adapter, drill it out and cut off just enough of the threads to expose the Delphi manifold air temperature sensor. I didn't want to have to pull the intake, only 1/4" fittings in the RPM intake. I moved the PCV and added a brass tee to combine it with the transmission modulator. I added the MAT just in front of the throttle body.
I got the new temp sensor for the Terminator, actually swapped spots with the heater hose, further down in the intake. I added the oil pressure sensor for the oil that the Terminator reads. I also ordered the 8 AN to 1/8 NPT to install the same sensor for fuel pressure just before the rail. The Amazon sensors are about 1/10 the price of the Holley sensors which aren't included! The other fittings and brackets and brackets showed up. I routed and secured the 100 micron fuel filter just above the rear axle. I installed the Mr.Gasket fuel pump relay and added a wire from the negative battery post to the fuel pump as Holley required. I had a spare 12 volts key on wire. It was just long enough for wire length between the Holley harness and the fuel pump relay wiring. Soldered, heat shrunk, all wire loomed and insulated hod downs throughout. I routed it down the passenger side. Turned on the key, could hear the fuel pump kick on and build pressure, lines squeaked and no leaks! I also broke down and got a MSD dual sync distributor on sale, which is plug and play with the Terminator harness.
I ordered a 10 micron element for my filter to replace the 30 micron element and different throttle and kickdown bracket with more adjustment, more solid and looks better from Amazon. I clocked my O2 sensor for the wideband and the Holley EFI at the angle Holley recommends and installed the Terminator X Max O2 sensor in the passenger side cat, now dual O2 sensors. I installed more of the sensors and I connected the thick red and black Mallory Hyfire box wires to the MSD noise capacitor. Will wire the rest of the ignition box today, distributor should be here by next weekend, along with the other parts.
The Hyfire box and main power are wired and routed. Most stuff connected, just need to figure out final routing and where to put the ECM.
So a couple of little things. The different throttle/kickdown cable bracket arrived, should work better. Also the 10 micron fuel filter element arrived. I ordered an LS knock sensor harness for dual sensors off the block and a second sbc truck knock sensor, thinking that would plug into the Holley harness, nope. They used a 3 pin plug, which doesn't really exist for knock sensors! Holley only sells a replacement for the one I already have! I think I found a couple of plugs I can make work. Basically the third wire is a ground. I have diagram and colours. I really don't want to cut the Holley main harness anywhere. I can cut the LS plug off the knock sensor harness and found the frequency for these truck sensors to program into the Terminator X Max. Getting closer to fire up!
Ok, so I installed the MSD Dual Sync distributor. It plugged right in, lined up #1 at 50 degrees as in the instructions, just need to check the LED for the sensor alignment. I also modified a 3 wire crank sensor plug to plug into the knock sensor plug into the Terminator X Max. The crank sensor plug needed the plastic ground down on the sides of the male plug to fit in plug. I cut off the plug for the two wire plug to the knock sensor and matched the wiring to tge two knock sensors and grounded it to the valve cover. I wanted the X Max ECM under the hood. I looked at $200 US boxes, nope! I found a $10 small parts container. It had middle dividers, I cut down but it is off the bottom of the box a little bit. I hole sawed and drilled for the three electrical plugs and MAP sensor hose. I put wire covering around the holes. I like that I can open it and access the ECM but is well sealed from moisture. Also the 10 micron fuel filter element is wrong so I ordered a whole filter, I will run the 30 micron to to fire it up and do a basic tune check. I installed the new throttle and kick down cable bracket, should work better.

I got to the Tuning Wizard, realized two things. I want the Terminator to control the fuel pump. It can run pumps up to 15 amps or just trigger them. Key on through the Mr.Gasket fuel pump relay isn't going to cut it. I actually unplugged the relay pissing around with this. Second, I didn't know my injector size. I asked Mark, he was pretty sure they are 50 pound Holley injectors. I was thinking 20 degrees as the static timing setting. I did find one small fuel leak last night at the drivers side crossover while messing with the distributor, hopefully the only one. I will do a good check over before switching the fuel pump wiring. Hopefully a fire up later today!
