A to Z

Has anyone been following the progress of these engines? The aftermarket is starting to really grow for this engine. "divlac57" is the guy who has been spearheading a lot of this Anyone else watching any of this come about??

I have had a lot of problems with the throttle cable and related parts. a late night job came up with an extremely basic solution for cable hookup at the carb....I made a bracket and got a brass cable stop at Auto Zone, and the gas pedal bottom edge hitting the floor keeping full range from happening were the culprits. FIXED.

Ok, so update....thanks to those who warned me about these Edelbrock foam air cleaners. I started reading, one back fire and they will catch fire and turn into goo and run down into your carb/TBI !!!!! oh no! So, i looked online, because this filter was also hitting my hood. I found this company: Pro Series Screens - Intensity Racing Products I bought the mesh screen to work on my carb mouth. So glad you guys said something. WHEW! see pic, I got the low profile with the single hole.. 98 bucks....115 shipped. Saved my life.

Day 4 of EFI install complete. ALL DONE. Time for remote tuning. pics and 2 videos at the end V1.MOV V2.MOV

I disconnected my throttle cable and lubed it up, now it moves freely with no drag, in doing so, I re-arranged some of the items attached to the carb thus cleaning it up. A short amount of time to work on stuff today and I'm happy I was able to get it done. Also was able to tighten the spring for the secondary butterflies which is basically required to keep them working right. My thermostat probe adapter that goes into the top radiator hose also arrived and snapped a few pics.

I was able to squeeze in a little time today and build a brace to hold my carb and intake up. Heim joints and all thread.

I got in a little bit of time on the EFI project today. re-ran my water meth lines....the way I had them was problematic.....kept trying to pinch the lines. Also figured out how to run a brace from the engine to the carb intake. I have some heim joints and 3/8" all thread....will come off of one of the 10mm smog pump holes in the block and then up to the bolts in the back of the intake. Small steps.

Day 3 EFI install, almost done!

08-21-2025 Day 2 progress pics. Fuel system fully installed and wired up in the rear. Same for engine compartment. One pic you can see I abandoned in place the old fuel lines up in the trans tunnel. You can see the T fitting I installed where the nitrous line can be installed at a future date when I'm ready to melt my engine down. The temp sensor that comes with the Sniper 2 is too large, ONE other company makes one, and it's a very small one, smaller than the size I need to screw in. If I screwed it into a bushing there wouldn't be enough of the probe sticking into the stream of antifreeze to work right, so what I had to do was cut a bushing down on both sides. I tried to thread it on, but it wouldn't budge, so I ground down the threads on the smaller probe and got the bushing (which was now basically a sleeve) to fit over it. I JB Welded it together, and by tomorrow it should be ready to install. Wiring awaits me and some other little do-dad's, and the finish line is within sight. I had to change my air cleaner, as the round one was too high and hitting the hood. No one makes a thin air filter for it.......So I went with the tried and true Edelbrock foam one, and it clears. Here are some pics:

Well, thanks! I appreciate it. it's a build in progress, from SU's on a stroker, to a Crown turbo kit in pieces..... that I customized the majority of for a DIY setup using a motorcycle Mikuni HSR 45 with a flat slide, to now EFI. I am just improving the system I have had, 1 step at a time. The Nitrous is just for looks. If I were to use Nitrous with the turbo, I am not sure the engine would survive......its fully forged, but throwing 2 power adders at it at the same time?.........Eh

Day 1 of installation. almost a 12 hour day and made some good headway. see below pics. click on pic.

Day 1 of installation. almost 12 hour day and got a lot knocked out. Pics below:

08-15-2025. Again, more parts arriving and I got a piece of 16 ga. steel painted up and then assembled my fuel pump and filters and laid it out and marked for drilling.

More parts came in today. Sniper 2 arrived, laid it all out, took some pics, and went ahead and used some thread sealant and put the pressure regulator together, and tried to take a pic of where it will be mounted. Psi gauge still in the mail. It will be "fun" making room for this HUGE sniper. There is a "hole" there, just have to get a couple cuts just right so everything fits. Took a few pics, first one is the "Master Kit" which is the fuel system, and it came with some NOS fittings.......then the entire deal and held it up on top of the intake and air cleaner....looks like I will be getting a thinner air filter to go in it, to clear the hood.

parts are pouring in.

ordered a 9" air cleaner and I decided I didn't want it chromed AND the sniper to be polished, so I took it to a local guy and had it blasted and powder coated gloss black to set off the sniper a bit. the bottom ring is only powdered where it can be seen, as it won't fit on the mouth of the sniper if the powder is on there...too thick. I think it will look ready good and contrast the polished stuff.

extra parts for the EFI conversion:

I took a BIG leap today:

08-09-2025. Polished out the top of the aluminum radiator and the trim in front of it today:

Thanks. the stock cam and the Diesel crank gave me that torque figure!

08-07-2025. DYNO morning. Found out a couple of things. 7 psi in 3rd gear WOT at 5500 RPM, 9 psi in 4th gear WOT 5500 RPM. She is RICH....rich to the point of fuel popping, 10.0 to 1, A/F rich, and didn't want to go past 5500 RPM (strange since on the road she will but nevermind). So, there is probably 40 horsepower left in her in the DYNO guys mind. We made 4 runs, and in 4th gear without using any Water/Methanol injection, it pulled 196.8 hp at the rear wheel, at 5500 RPM and at 18% drive train loss that is 232 hp at the crank@5500 RPM. Torque was 268.3 at the rear wheel, 316.59 at the crank@ 5500 RPM. Boost was 9 psi at 5500 when he had to let out because it was so rich. We did a run in 3rd gear WITH water/Methanol and it pulled 226.7 hp at 5500 RPM at the rear wheel, so 267 HP at the crank@5500 RPM and 260 torque, which is 306.8 TQ@5500 RPM, boost was 7 psi. So, as I thought when building it, the stroker and the stock cam made it into a torque monster. well over 300 ft lbs. torque, 232-267 horsepower.....but it is PIG RICH. So, power is limited by being rich. I have dyno charts, but the RPM range at the bottom is all wrong. we weren't able to get to 6000 RPM because of the rich condition. He said it was basically 10 to 1 A/F on the runs, which is WOT, so the main jet is just too big. I can step it down one. As expected, the carb is the limiting factor. At any rate, this is where this engine setup is at now. As predicted, it is a torque monster.

I will post the dyno sheets, but as I said the RPM range at the bottom is wrong. he let off at 5500, I wanted 6000 RPM but he said it just wouldn't do it., when he let off the throttle the unburned fuel was popping and banging.
