1973 Rebuild
Drivability will not be an issue with a performance cam. Go with as much performance as you want. Go 490 lift !! My point is don't limit the cam size based on what you think will be street friendly . My 490 /290 idles at 750rpm and pulls around town in 5th gear at 1500rpm just fine. If looking to keep stock springs and valve guide seals , then that's a different story . Sounds like you caught Ron on a good day, but I have seen 2 times that he sent the wrong cam card with the cam. Not much support after the purchase also. Stock cam regrinds are common and best . I would make sure I go with an internally oiled cam . Sent from my iPhone using Classic Zcar Club

Painting Engine Compartment
I think it's doable to try it with the engine in -especially since all the accessories are out of the way. Get a jam gun or even an airbrush and go for it. You can crawl all the way in the compartment if you need to and get a better angle. Engine out means you can paint it easily as well as any service or paint to the crossmember . Without engine you could pull the brake lines further away from the firewall to have an easier time painting.

The easy remedy is to buy the inserts for the hydraulic head so the mechanical lifters just screw in. But maybe pics will verify that we are all talking the same thing Sent from my iPhone using Classic Zcar Club

New project-72

Rear suspension is done and I drive her down the highway yesterday !! Despite no door seals , hatch seals and a leaking muffler - it was a bit of a victory drive. Fumed out a bit from the lack of seals and a rich mixture didn't wipe the smile of my face at 65 mph More tuning to do and some temporary seals will make the ride even better. The engine ran very strong though it's lack of maintenance should say other wise . The last original engine component - water pump- gave out shortly after the highway run. Too much rust to injest and it threw it all up in my garage over night, Hopefully the rust treatment for the block got most of the nasty stuff out . Time to drain and put antifreeze in. Transmission shifts hard from 1st to 2nd gear, but I guess that's better than slipping into gear. Other than that the auto box works pretty damn well. Might need to take it for a fluid change and band adjustment - even that can be done on the Jatco.- Water in oil!!!

Another run with better results. I set the needles flush with piston , not groove. I'm 2.75 turns out now to avoid lean pop, but there's more power there to be had. Going to drive it around like this for a while. Also not running air filter so that leans things out. I've seem to have lost the captive nuts for the backing plate - if anyone wants to sell some.

And when I say over flow I mean shooting out the air vent Sent from my iPhone using Classic Zcar Club- Quick and dirty SU Tuning
I guess it was too big of a tweak- . Backfiring happens during tip in under load at lower rpm. Might need to play with timing a little. Not running a vacuum advance at present since this dizzy is a d6-12 with 24!degrees mechanical advance . At present running 12 static . I'll be back at it today Sent from my iPhone using Classic Zcar Club- Quick and dirty SU Tuning
Mark, The carb overflowed after trying to richen FLOAT LEVEL. . Just did the 10 turns down and seeing fuel method to check float level. Went out for another spin after putting piston needle shoulder flush with the groove. Engine pulled harder but have run out of sunlight until tomorrow. I know I have run the needles like this on my car before with good results (SM) Sent from my iPhone using Classic Zcar Club- Quick and dirty SU Tuning
Need some tuning advice so I'm tagging on to this thread . SU's idle good and drive decent , but getting some lean spitting out the carbs. Pulling on the choke eliminates and adds gobs of power . Already 2.5 + turns on the little L24(stock), but it wants more. SM needles installed , timing checked, idles too good for vacuum leaks. Plugs showing rich idle but lean white burn on tip. Big question for me is where the shoulder of the needle should be relative to the piston. Flush with the groove or flush with the bottom of the piston. Float levels have been checked numerous times. Just tried richening them up and overflowed one. Help me- 83 280zx turbo half shaft CV's

Very fixable if you have amazing talent and a frame straightener and lots of time. That's hit hard Sent from my iPhone using Classic Zcar Club- Anyone running MegaSquirt in their Z?
I'd have to re- read my own thread to know for sure . No resistor in the wiring for sure. Okay, looks like I put a 1k at 57. You need some pull up resistor somewhere . You could try in the wiring first, but somewhere you need one- Anyone running MegaSquirt in their Z?
There's discussion on both VR sensors and hall sensors . MS made it hard for me to differentiate between the two, so I thought any reading on the subject was good. There- Anyone running MegaSquirt in their Z?

Okay- so I have tried to add a link and it doesn't show up . Chris, I had started a thread on MS forums on this issue and I am trying to post link, but I don't see it Sent from my iPhone using Classic Zcar Club - New project-72
