Sounds exactly what you get when the reaction disc falls of of the Mastervac plunger. Did you remove the brake Master cylinder? If so did you pull the plunger out of the Mastervac? If so, the little round rubber disc that fits on the back of the plunger probably fell off. If you didn't do these steps, I'm at a loss for what it might be.

Geometried the head with my Stage III Isky cam.....wipe patterns are checked. Will take it to Eiji Monday....he'll cc the chambers, assemble the head, then time the cam. I'll bring her home and finish it up in the next week or so.

You're right LeonV, the word I should have used is inertia, not torque........that's what I feel like I need for stoplight to stoplight and launching the quarter mile.

I understand where you're coming from Mike.....but I'm looking for inertia.......me and Eiji have an ongoing friendly competition going on in straight line racing.

This one is exactly 20 lb. .............

BTW.....I'm still not sure which way to go on a flywheel. I'm going 240 mm, but not sure if I want to go light or not. I have a stock 240 mm flywheel that was lightened by the Z Doc......Eiji uses a 12 lb. flywheel. I'm leaning towards the heavier wheel as I spend most of my driving where torque is needed. I know the 12 lb. wheel will spin faster, but a heavier flywheel will be easier to drive at stoplight to stoplight and in a quarter mile sprint! Any thoughts?

Not sure riceburner. I'm spending the day with Eiji Monday to finish building the motor. I'll ask him. If you want me to check on anything else. Cheers....Guy

You are right Zedy, but there is some adjustment that can be made to fix that without modifying the stock valence. If you crawl under and take a look, there are some bolts that can be loosened to adjust the valence forward to get a 225 to clear when you are backing up.

If you run coilovers and drop your Z anywhere below stock height, you'll need camber plates and to tuck 'em in 3 degrees to keep 225 50 16's from rubbing. In my experience.

Yes I have and yes it is......pretty much.

Eiji says he's hit 10,000 rpm. Impressive, but I wouldn't want it to live there long.

No spacers....not sure about offset.....wheels were on the car when I bought it.

These are 15 inch wheels, but I have Wilwoods on 16 inch wheels too.

Not a Ferrari folks......it's a Datsun Spirit L28 Stroker with all the goodies! Not mine, but I'm getting excited. IMG_0854.mov

You know it Mitch.....not sure if they will be Mikunis, but there will be 3 side draft something's hanging off to one side! I know if I didn't, you'd never let me hear the end of it.....you and my son Brandon win.

P79....shaved .080 inches....Stage III Isky cam. Guy

Yes they are still out there.... a friend of mine just sourced a passenger side quarter for $1200.00. Had to weld up the vent for his Series 1.

Yeah.....Totally new territory for me....So glad my buddy Eiji is close by. I'll take the head up next week and work with him to put her together. He says 89mm bore...83mm stroke .3mm above deck....90.5mm x 1.29mm gasket....44cc head volume and 5.2cc piston volume. He said a 10.7:1 CR. Like I said....new territory for me! Anxious to see what she'll do.

Eiji buttoning up the bottom end of my stroker 3.1.....he really pays attention to detail. Can't wait to dyno this new puppy!

So sorry German 240......didn't mean to hi jack your thread....will start one....good luck with your build! Guy

Gone!

Still do....... IMG_0824.MOV

Think that may be Bob Leitzinger's 510......

How does that work....can you explain how you use this device?

Cliff....Yes the 72 intake and balance tube....disconnect manifold water on all my cars. The 73's had a large chamber head....very different from the earlier cars....the only real difference that I can think of.....maybe it gave off more heat. Someone posted somewhere that the fuel pumps were different, but I can't see where that would be a problem.....but something causes these cars to vapor lock.
