Eiji built my head with a Schneider .495 lift cam....he used .220 lash pads....centered perfect. .160’s should be about right for a .460 Cam. Trial and error, since the valve stem height can be different on machined heads depending on how much the seats are ground. Try the .190’s......might work. German240....I like the permanent green dye idea......

.......and not a foot pound more. Also, since they are threaded into aluminum, try not to take in and out more than is absolutely necessary or you’ll pull the aluminum threads (requiring installation of threaded inserts).

Couldn't agree with you more Capt. .........This looks like a $15,000.00 car to me.....dream on Motorcarclassics.

Fill the master cylinder with brake fluid. Remove dust cap from bleed screw.....slide tube onto bleed screw and up into reservoir. Open bleed screw and get helper to slower push in clutch pedal until no bubbles. Lock bleed screw.

Yes, but the Datsun gods didn't make em that way, so it just bugged me. Wasn't functional either. Mike....I never slept in mine, but many, many times, there was a third passenger riding in the cargo area......but then again, when you are 21, you are immortal! Site....You are right....added to my first garage, but the County wouldn't let me build the third addition......probably better....can't drive what I've got, and wouldn't want an empty garage!

Old picture Cliff......there’s 2 Z’s under those blocks now.

Got Chuck to remove the passenger side mirror from my white 70........it’s always bugged me!

Nice!

A modified shifter will solve the problem.....

Great choice.....right Jim Arnett?

Not true.....5 years later....still perfect....oil and gas have had no effect......just wipe off.

If you look inside your valve cover, you can answer your contamination issue.....yes it will contaminate your valve cover. VHT is a high temp paint, although the valve cover doesn’t get that hot, I still prefer a higher temp tolerant paint. I use aluminum color.

Here’s three that I did that way.....

Bead blasting will make it look great....especially if you you spray it with a VHT aluminum paint. Just make very sure he screws it down tightly to a piece of wood (with a gasket) and tape up the vent on top to keep all contamination out of the valve cover.

Just saying.....if it runs cool when moving, but overheats when at stop lights or just idling, it indicates that your air flow is adequate will moving, but not while idling (fan clutch). If it overheats while moving, you’ll need to look further.

Does the engine run normal when driving (moving) down the highway?

Feels like a fan clutch to me. Had the same problem with my Stroker....new clutch was defective....put another clutch in.....works perfect.

Where did you buy them Moelk and how much?

That’s my boy! This is going to be a really fun father/son project. Finally got the kid back in a Nissan/Datsun. I’ve only built the L Series engines.....looking forward to playing with a twin cam beast. You’re going to like this car........ I promise! BTW JSM....I joined the site March 2007....I see you joined in April 2007 Guess that makes me your Senior eh?

I would look at your fan clutch like Site suggested. I put a brand new one in my new Stroker motor. The engine ran cool when moving, but at a stop light or idling, she would over heat. I replaced it with an old one and it solved the problem. She now idles dead center.

Thanks Cliff. Since you are so far away, I'll have to share them with some of my other friends......

Funny you should mention boiling some jumbos Cliff. We are getting ready to boil some jumbos too. Millie will be watching.....not eating the procedure!

I would guess you've got at least one, maybe two stuck float valves. When a float valve is stuck open, it feeds gas into the air cleaner housing.....just like your picture It's normal for the float chambers to move.

I agree Capt. ......all of my Z's idle at 1000 rpm when warmed up.....not so when first cold started. Modern engines seem to have a sensor to adjust for this.
