      Cool build, I like how you're taking on most of it yourself! I really like how the stock look to your motor and I may have to steal the OBD port in the ashtray idea from you. Keep up the great work!

      Feel free to steal that idea! I put a lot of time into thinking of places to hide basically everything inside the car to keep the interior looking stock. Basically my hope is that someone who looks at the car may actually believe it's a big block in there, so having everything hidden on the inside will help with that.

      I'm lucky enough to have access to a lot of resources that allow me to take a lot of this on by myself an it's certainly not all me, my dad is one of those resources and he always gives me a hand if I run into a snag or I want to bounce an idea off him.

      In regards to the 4l80e gear ratio, I ran 4:10s. No complaints, with a torque converter its going to be perfect. LS engines are pretty pathetic under 3000rpm so the converter helps kill that dead spot.

      Some more work on the cowl induction aspect. I had to modify the pedal bracket that the inner door switch mounts to because of my aftermarket pedals. Here is what I started with

      and the finished product. It doesn't look like a huge difference but things like this take a lot of trial and error to make sure they work correctly.

      Here is how it would function originally,

      and how mine functions now. After having the bracket in and out 10 or 15 times I got it right, the pedal arm actuates the switch completely open just as the pedal travel bottoms out. So essentially the switch is activated at full throttle.

      For the next part of the cowl induction, I had to figure out was how the air cleaner was going to fit with the hood. I was worried I would have issues with the air cleaner not being centered in the cowl area of the hood. With a few slow closes of the hood checking for clearance, things were looking pretty good. I did end up trimming the original spacer to clear height wise, but the air cleaner lined up perfectly.

      I trimmed about half of the spacer

      After some finishing work this is how it sits. I used a cutting wheel and took my time to keep the cut as flat as possible, then I finished it with a sanding disc and a file.

      With the air cleaner fitting nicely now I went back to finish up the fresh air side of the PCV. Since my catch can is on the passenger side, I ran the passenger side valve cover as the dirty side to minimize the amount of hose in the engine bay. The clean air side hose is basically invisible because of the way it's run. The clean air side starts at the driver side valve cover in the rear (that is where the ports are on these adapters), it then runs across the back of the engine and into the coil area of the passenger side valve cover.

      The hose then runs into an elbow that goes through the valve cover and then to the original port on the air cleaner. This gives the look that the PCV system is run the same way as a factory big block but in reality it isn't.

      Also visible in this picture is the transmission dipstick. I used a Lokar firewall mount, it hides pretty well behind the air cleaner.

      Here is a better look at how the rad cover came out, I'll probably pull it back off and epoxy primer it and repaint just to cover some of the finishing scratches that aren't really visible in the picture. I also need to paint some of the bolts (and clamps on other things). The rad cover is basically two original style covers meshed together to accommodate the additional width of the electric fans.

      I sent my headers to get Vbands welded on (TIG is something I need to learn) and I'm waiting on my driveshaft to show up, other than those couple things I'm ready to try and start the car for the first time. I have a tune loaded into the ECM that should get the car to start at least. The headers are also preventing me from putting the inner fenders back in and fabbing up a new exhaust system (I had a flowmaster kit for the car but it won't fit in the current configuration, so I'll use pieces of it to make the new system).

      Here's an idea of how the engine will look, there's still a couple things I need to add from when this picture was taken but this is close.

      That's almost close enough to call it original lol, I think that really adds to the car and I love the story behind it. My grandfather is into cars too but he always liked fordslol, if only he had bought a chevelle when new I'd be all over it!

      I'm happy with the choice of torque converter, the cam is supposed to start working at 3000rpm so I should be just into the power band with the 3500 stall

      Nice job on the cowl induction and giving it an overall original look and feel under the hood.

      Given your intake setup, I am surprised that you didn't go with a Holley Terminator X, or other Holley EFI system.

      Looking back it probably would've been easier for me to use a Terminator system, but when I originally started I was planning on keeping things stock so I bought hptuners. the decision to buy hptuners was something I thought about quite a bit an I decided that since I was planning to LS swap the chevelle, my 56 bel air and possibly my c10 along with my dad's c10 and possibly others that I would be better off learning how to make my own wiring harnesses and tune myself. I really like the holley system and if this was going to be a one off for me I would've certainly gone that way. With trying to stay budget conscious I decided this was the best way to go. I may still decide to try the holley system on my bel air project because I'd like to run a dual quad throttle body set up (similar to your cougar) and that would certainly be easier with holley.

      It was definitely a blessing!

      Side note, do you happen to have the part numbers or application for the upper rad hoses you used?

      The hose is a mashup of 2 or 3 others, it's part 2014 camaro and part tri five chevy. The camaro was an LS3 car and the tri five was a 6 cylinder. Then I used some pipe to connect them. I may be missing something, for some reason I think I used some of the original chevelle hose. It was all stuff I had so I made it work.

      No worries on the hose or the trans. If the overdrive is where you want it with the 4.10s, it should be fine as-is. On the truck I did I was running 3.42s, and with a 4L80E's 2.5 1st gear it was a real slug on takeoff but I wanted the rear/OD ratios where they were. X2 on the original look, it would take a real nitpicker to tell the difference, especially when you look at the exhaust and see that it's got the same pattern that a big block does (no siamesed exhaust.) You've done some really good work there.

      Thank you! I can definitely see it being a slug with 3.42's.. I know my chevelle is two completely different cars with each of the rearends I've had in it (3.08's and 4.10's)

      Not a lot of progress yesterday, things are starting to slow down as I get closer to firing the car, mostly waiting for parts at this point.
      Started the day out trying to fix a pesky problem with the ash tray. Since this is an aftermarket dash it doesn't fit perfectly everywhere.

      This is how the ash tray fit before any modification, the back was sucked up into the dash and the front wasn't up tight enough for my liking

      I spent some time blacking out all the clamps (including the ones on the coolant crossover) I also added the air cleaner and valve cover stickers to further the look.

      I'm debating what to run in the passenger side valve cover. This picture has a PCV valve with some hose (run to nothing because it won't be functional) similar to what would've been on the car in a factory big block application (although not exact). My other option is to just run a chrome breather in that side. Any thoughts?

      Well not much progress today. If anything the car went backwards. I managed to snap a bolt off in the rear end housing and it caused a world of headaches.

      I'll have to pick up a new cover gasket on Monday and slap the cover back on.

      After that disaster we rolled the car off the hoist and into the next bay. I snapped a couple pictures of it out in the sun. Wow is it ever dirty!

      I've been doing a lot of looking and thinking about wheels for the car. They'll be 18's but I haven't decided on a style yet. I'll post more about this in the future but if you guys have any suggestions let me know.

      I ended the day helping dad out with his 57. We just recently swapped the rear end and decided to put some caltracs on, which just got buttoned up today.

      Plans for tomorrow include putting in the passenger side inner fender (the drivers side will go in after the headers are back) and finishing up the A/C wiring. I'll also likely measure the car for wheel fitment. I'll be running 285/40/18 on the rear and I'd like to run 275/35/18 on the front but I already have the 285 so i might try it on the front just for fun. I'm guessing it'll be too tall.

      On another topic I ran into some issues when test fitting my wheels. The wheel fitment tool contacts the tie rod. I was testing with an 18x10 which I believe should fit. Iím going to test fit an 18x9.5 wheel that I have to see if the wheel tapers enough to clear. I was hoping someone here might be running a similar wheel on the front of an A body and might have some insight

      18x10 will fit with the correct backspacing. What is your fitment tool set on, 6" should be about right on that width. Also I would be jacking the control arm up into the fender when to see how the suspension sits with weight on it if you're not doing it.

      Thanks guys. Iíll double check the tool but I believe it was set on 6Ē, I think it was just the design of the tool that was throwing me off. Iíll definitely be jacking up the control arm but the tire I was using is too tall and wouldnít fit.

      andrew what are you running on the rear? I was planning a 275/35-18 for my front

      In the rear I run a 295/35-18. Having said all that, I will probably go with 275/40 and 295/40, front and rear, respectively, next tire change.

      If you donít mind me asking, why the change in tire height? Are you running inner fenders?
