Everyone should wear a name tag with their "Classic Zcars handle" on it so we know who you are! :laugh: What about it Will?

Have you tried your local dealer....I bought one new last year from my Nissan dealer along with new right and left front fenders.

I agree with Arnie....1mm is .040 inch overbore...... .75 would be .030 over. The idiot that built this engine missed a couple teeth on the timing chain. .013 out of the block shouldn't be a problem unless you've got a very high lift cam. Use your new head....... make sure your bright links are where they should be and you should have no problem. All IMO. Guy

Very....very nice!!! Nissan has new horn buttons.

An F54 short block with flat-top pistons will work fine........If you install the pistons in your block install new rings, hone the cylinders, new bearings and you should be good to go. The P90 head shaved .080 with .080 shims on the towers and valve springs should give you slightly under 10 to 1 compression. Here's a similar build........ http://www.classiczcars.com/forums/showthread.php?t=34448

Thanks everyone.........I appreciate your input.

Rob......I wouldn't recommend that you try to change the side seals while the engine is in the car. You have to remove the rear bearing cap to remove the old side seals. This is not an easy job. I don't even know if it can be done while in the car without a special tool to remove it ( extremely tight fit). I don't think side seals even go bad ( never heard of it happening). If a seal is leaking, your chances are 99.9 that it is the rear seal (a relatively easy job once the tranny and flywheel are off). Be careful when you pry it out with a screw driver or seal puller that you don't gouge the polished area of the crank that the seal rides on. Good Luck......All IMO. Guy

Anyone found a modern touch up paint that matches 904 white for the early 240Z's? Something that you could readily obtain at NAPA or Pep Boys etc?

Same here....I have 2 F54 block L28'S with the p79 head shaved .080 inches with .040 over flat-tops running 10 to 1 CR with no sign of a ping. I've heard the more duration the less problem. Both run stage III Isky cams with .490 lift. Both are a blast to drive!

Timing gear, chain sprocket and damper. You can get them at your Nissan dealer, MSA, Black Dragon or you can always buy them from Redat on eBay.

Nice job cozye........keep up the pics!

No.......The links won't line up for a number of full rotations.

I just put a 5 speed in my 73 auto car. The starter that was in the car (original starter) works perfect with the 5 speed.

It's very expensive ($150.00).......I didn't notice any real advantage. Especially if you're running stock.

A job well done........the right way! I love viczcar.com...... the Aussie's really have some nice early Z's.

Me too......beautiful car!

......then divide by 5.

I'm with you on that......

Make sure you took out the two little bolts in the front of the head!

Geezer......How was the installation.....did they fit as original? Guy

Hi Brian.....They are valve reliefs cut in the top of the pistons. Yes you've got the same set up as Chris, but you've got the big chamber E88......I've got the small chamber E31.

Brian.....Enjoyed seeing the progress today. Won't be long till she's on the road! Guy

Hi Eiji........Hope your shoulder is getting better.....salt should be off the roads soon. Time to do something with the Virginia Z's. Regards. Guy

Chris.....That's the head the pistons were designed for.....You've got no problem.If you look at your block pictures,you can clearly see the .030 edge I'm talking about sticking out of the block. My question is......is it OK to run these pistons without modification with the early E88 or E31 heads where the chambers are designed for the "0" deck clearance flat top pistons. If anyone has used the 73 flycut pistons with the early heads, I'd like to hear from you. If the pistons you installed had valve reliefs whether Nissan or aftermarket, they are 73 pistons.

Chris....Are you running the early E88 or the 73 E88? As Arne mentioned....maybe the 73 head had a different combustion chamber with more clearance. I would like to hear from someone who could confirm this.
