      ^^ THAT.

      I knew the stock 7.5 axle wouldn't survive behind the big block, so I swapped it out for a Fox-body 8.8 axle. For the time being, I am running Fox wheels to match. Eventually, I plan to do a c-clip eliminator and an axle shaft upgrade on that 8.8, at which time I can have the new axle shafts drilled for my stock 5x4.75 pattern. I may also re-gear it at the same time if I think it is necessary (it currently has 3.08 gears)... but for now, what you see is what you get.

      Last night, a co-worker and I dug into my front suspension to install my new springs and shocks. He had recently done a spring swap on his '84 Camaro, so we both figured the process would be the same. It was similar, but we did need to adopt a couple different procedures to make it work.

      We put the car on a lift, disconnected the sway bar, and unbolted the bottom of both shocks. We placed a transmission jack under each inner ends of the driver side lower control arm, then removed those two bolts. Now we slowly lifted the entire car, allowing the control arm to slowly drop down from the inside until the spring was loose. The new spring was put into position, then we gently lowered the car and fiddled with the jacks until the arm ends went back into place. We reinserted both bolts and got the nuts started. Not bad, we both thought.

      I paused to take a photo of one old spring next to one new one. I expected the new ones to be shorter (unloaded) than the old ones, so I was quite surprised to see this:



      The passenger side would not be so easy. The biggest problem was that one header tube runs right below the arm mounts, ie directly in the path we wanted the control arm's rear end to take. Instead of just letting the arm ends drop straight down, this time we'd have to get them to move outward at the same time... and, if we were lucky, the spring wouldn't fly out and kill us in the process.

      We got the old spring out, put the new one in place, and started to move the arm ends back into place. This is where things got difficult, as this arm fought us every inch of the way. We would stop, analyze the situation, lower it back down, adjust the jacks, and try again. We must have done this six or eight times, always with it stubbornly refusing to go where we wanted. Dallin came up with an idea of just trying to get the front arm partially into position--just enough to get its bolt through the forward-most hole. We managed to pull that off, which at least made us feel less unsafe since there was now another anchor point holding the compressed spring in place. Now we could focus on just getting the rear arm mount high enough to be in the correct plane, though it was way too far outside its frame mount. That's when my co-worker Dave passed through to see what we we up to. "If you guys had a ratchet strap, you could pull that outer arm end rearward and it would go right into place." I went rummaging through the shop, found a ratchet strap, and followed his suggestion. Like magic, it went perfectly into place. Wow! At last, we were able to properly insert both bolts on this side.

      By now it was past the time when Dallin had promised his wife he would be home. Oops. We quickly reattached the sway bar and torqued all the control arm nuts. He thought we could quickly swap the shocks and be done with the entire operation, but of course the 37-year-old upper nuts were pretty much rusted in place and didn't want to budge. Dave came back out and suggested we grind off the top. We started to do that on the driver side... it was taking forever... and we ultimately had to break it off after the grinder had cut it halfway through. I told Dallin not to worry about it any more tonight; I would just park the car outside and have Dave take me home. So that was it.

      This morning, I was able to get a photo in the light:



      I only moved the car about 100 feet, so I'm sure the springs will settle a little. Even still, I am thrilled to have the nose up at stock height. There is still a slight bit of rake, which is also fine by me. This turned out about as good as I could have hoped.

      Now, to get the shocks installed....

      I'd say lookin' good, but that doesn't seem quite right.

      Ride height lookin' good.

      The new shocks are installed and everything is buttoned up on the front end, so I decided to drive the Grand Prix to work yesterday for a shakedown run. I'm quite pleased with how the car rides. I'm sure it's no slot car, but at least both ends are balanced as far as firmness and suspension response are concerned.

      On my way home, I was on a three-lane concrete road that crosses over some railroad tracks. I was in the center lane, doing between 40-45 MPH as I approached the overpass. As I began climbing the hill, the car in front of me began to slow because the car in front of him was doing the same... even though nobody was in front of him and the stop light on top of the overpass was green. I could see our light was going to change soon, and if the first bozo kept slowing down we'd all have to stop. The right lane was empty and nobody was coming up from behind, so I hit my signal and started to change lanes. Just as I crossed into the right lane, I gave the throttle a light prod--at least I thought it was light--in order to coax the TCU to drop down out of fourth gear and into third. The computer was perhaps a bit too eager, because it went right past third and instead dropped me into second gear. By now I was steering a bit to the left so as to follow the curve of the road, and the sudden onset of torque caused the tires to break loose and the tail end began sliding out to the right. It completely surprised me, but I quickly lifted off the throttle to kill the wheelspin, then got back on it much more gently in order to remain in my lane and safely crest the hill.

      I am quickly realizing this car commands complete respect from its driver.

      I've put close to 300 miles on the new engine by now. Things seem to be working reasonably well. There are still carburetor quirks, of course, and those just make me want to install my EFI sooner rather than later. But I need to shift my focus to Jeep prep for EJS, so I doubt I'll do anything else of significance to the Pontiac until after Easter.

      I did record another clip at idle, just so you all know I really did fix my header leak. (I wish my phone would record at louder volume.)


      Driving this thing makes me happy. As I've mentioned, the EZ-TCU provides firm, solid shifts even without telling the computer to go overboard. If I gently roll into a bit of throttle from a standstill, it will reliably bark the tires on the 1-2 upshift. This controller is much more aggressive than the OEM programming in my Suburban.



      Anyway, I'm having fun.

      Brain fart! This morning it dawned on me: in last night's post I completely forgot to mention curb weight.

      Yesterday while on a casual drive in the GP, I realized I was in the general area of the recycling yard where I weigh my vehicles. The car was relatively empty as far as needless cargo goes, and the gas tank was essentially full, so I decided it would be a good time to find out my "after" weight so I can compare it to when the car was stock. Without further ado:

      Stock (all iron 231/3.8L V6, 3spd auto, 7.5" axle, single soda straw exhaust): 3,300 lbs
      Modified (454 w/iron heads, 4L80E, Ford 8.8 axle, dual 3" exhaust system): 3,740 lbs

      Amazingly, it seems I've picked up enough extra power to overcome the additional 440 pounds of mass.


      And speaking of full tanks of fuel, for the first time with the V8 I calculated my mileage when I filled up yesterday morning. That fuel was used nearly 50-50 between city and highway driving; I managed 11.75 mpg.

      I should have weighed mine, but I'm just going from a 350/350 combo to a 6.0/4L65E.

      But wow, I can't believe the weight difference is that huge. That Big block is a heavy beast! I imagine your trans is super heavy too.



      Also, I have a video up of mine running, so we're getting closer to your roadtrip.

      An extra 440 pounds of road-hugging weight. Still lighter than my aluminum-block 6.2l car!

      Yep, lots of cast iron there. Half the reason I want to swap to aluminum heads is just to drop a hundred pounds off the nose--the extra power and torque will just be a nice bonus. And everybody says the 4L80 weighs a ton, which I believe after trying to lift it.

      I'll go looking for your video (which I presume is in your Camaro thread).

      Make sure you check out Finnegan's Garage YouTube channel. He does a direct weight comparison on a big block between the stock vs. Aluminum heads The weight savings is pretty substantial.

      And yeah, its in my Camaro thread. Search for "Mullet"
