Fortunately the frame rails -front and back- and inner and outer rockers are completely solid . When I built the rotisserie I added extra support up front by attaching to the sway bar points . Cutting the roof has advantages as far as storage . Makes for a thin profile on its side . It was hard to find a roof that someone was willing to part with or wasn’t already rusted . Being in the Midwest didn’t help . Finally made a connection with a guy in CA and his 70 had gotten totaled in a front end wreck . It was a PITA but we managed the logistics and he was willing to help ship it out . And it was the right color - lol .

It seems I’m having trouble finding more pictures of the car before I dismantled it . All the exterior panels were in decent shape . Someone went crazy with the red primer and painted everything including inside the engine compartment. The roof had some rust holes that turned out to be worst case scenario . In fact the worst rust found on the car was the roof including its substructure. I thought I could do a skin job , but there wasn’t much to weld too. My only option was to put on a whole different roof . The job was daunting and I tried to get a friend who ran a body shop to help me . Meanwhile the car pushed to side while I looked for another roof and I took on other projects. I did brace the car and cut the roof off . I separated it from the factory location at the rear quarter but decided my approach for the from would be to go for the middle of the A pillars . I realized after searching for a long time that I was on my own to come up with a method . Couldn’t find any documentation for anyone else doing something this evasive . Lots of stuff regarding chopping roofs - which is basically what I’m doing .

Well I wanted to get back to posting here so this will keep me busy posting . Years ago I had a friend that had this car sitting at an apartment and it was about ready to get towed off . I offered him all my money in my PayPal account ( 800$) even though I didn’t have a place for it . It was sell it or lose it and he was just glad it didn’t get hauled off . My garage(workshop) wasn’t even done yet but there was a z waiting . This was 2017 . A year later I had surgery on my back so it sat around for a while . It was a complete car with a blown engine . It sat outside for years To be continued

I don’t know . Bruce and I left the banquet to work on his car before they announced it .

I went to a local glass place and they had clear windshields for 105$ each . I bought 3 !

Glad to be alive . I’m a lucky guy for sure . It’s fancy but it’s all business too:)

Today I didn’t do anything but drive it !!

Finally figured out what was up with my log ins . Anywho- went to ZCON . Me and a buddy drove down the 4.5 hours from Indiana . The Z drove great with the freshly tuned ITBS. Had most fun in the parking lots talking nuts and bolts . Finally got to meet Captain Obvious . Wish I knew he was there earlier and could have spent more time hanging out .

Take good care of that head if it’s really a MN head . Like said - a compression test would show pretty stout numbers with any combo involving a Maxima head . CC’s are about 39 which should show 180-200 psi compression check . I’ll also say the Maxima head would be about better than anything you could pit on that engine . But it also would be a challenge for stock EFI to keep up with the compression - not even talking ignition timing issues also .

I thought it was rubber soul version which might be larger . I’d like to run 75mm horns but might be limited to 50mm . I’ll be running 45 ITBS . I still have my custom air box I might run . thanks

Trying to find info on this cold air box . How tall of velocity’s fit under there ! I’m doing ITBS and contemplating stack heights thanks

Triple sure look cool but I don’t miss them - especially what you are going thru plus all the tuning .

Well this is the point where you need to decide whether to continue with the OEM EFI or go programmable . Yes the 123 ignition basically drops in with some wiring to adapt to factory wiring . It’s 600$ approx. You should watch a you tube video on it . Same amount of money would get you a basic programmable ECU like a Megasquirt . Then you would have full control of the engine with many options - ESPECIALLY if you want to modify your engine one day .

As said above - using MAP density tuning - KPA would be your measurement for load. Tuning for cruise would be difficult not knowing how the engine is loading . Loading can change a lot just climbing a slight grade though you aren’t putting much throttle to the engine . The OEM injection biases everything to the rich side to be safe . Those plugs took a while to look like that and most of the time we spend in cruise . That’s why the 123 ignition is a nice supplement to help keep the engine safe while tuning since it does have MAP sensor

What KPA is cruise running ?

Plugs can verify what you think is a proper tune . I’ve been running programmable EFI for years - those plugs look bad . Something is not right . 17’s would be terrible for an engine that doesn’t have full spark control. I run my engines lean - even my stroker and 15.5-16 is a lean burn for these old engineered engines . I appreciate your effort to make these old Bosch systems tunable - but without any load readings( I assume you use standard dizzy) you are guessing . i would recommend a 123 dizzy if you don’t already run one .

Those plugs show lean and or hot - I would be concerned if my plugs looked like that . I haven’t read your complete thread , but those do not look good

I had issues with an AEM wideband myself . The O2 sensor was bad and the gauge would go full lean after running the engine for juts a minute . They send me another one and mad me cut the old one in half and send them a pic of it cut in half . Got another sensor - same freaking thing . This time they said they wouldn’t warranty it - only get one sensor . Googled all this and read of the many complaints of customers . Bought a different brand sensor and no issues

While you’re at it 🙂 - take your dremel tool with the biggest drum sander you have and clearance those areas I highlighted . Installing the larger exhaust valves will have a harder time breathing with the shrouding of the chamber . Etch a line from the HG and sand a nice radius to allow them valves to breathe . The engine will appreciate it .
