454 Powered Datsun Z Car......

Hey guys, I just thought I'd share my little project with you all.

I know some are wondering why a big block when you can built a stout SBC for less? Well, because I like to be different. I've seen a few BBC Z cars, but all but 1 or 2 used motor plates to mount the motor. Motor plates work, but I wanted to drive the car anywhere without shaking the fillings out of my teeth.

Though it is true that a BBC weighes more than a SBC, it isn't by too much. Plus the increased power (torque) will easily offset the weight gain. But its not like I put a V8 in the thing in the first place to go autocrossing either.

I am upgrading my cooling system with a new aluminum radiator from Summit, which I had my brackets heli-arc'd onto the radiator tanks. No electric fan this time either, instead an engine driven flex-fan will be used.

I am continuing to use the stock R200 rear diff and the stock fuel lines with the Holley 'Black' fuel pump I used with the SBC. This pump is enough to get the car moving for the street, but not for racing.

The exhaust is a dual 3" setup with a modified Flowmaster. To be honest, its way too loud for me. I am going to end up having Dynomax UltraFlo welded race magnum mufflers under it before too long.

The next phase in the project is to get my R230 installed. I will have to get another custom made driveshaft for the R230 installation too. Afterwhich a new fuel system including 1/2" fuel lines, and a Aeromotive electric fuel pump. I also need to buy new rims and tires, prob Weld's and BFG's

Hopefully I'll have a 10 or 12 point roll cage installed over next winter.

After these mods I'll be ready for some racing next season. We'll see I guess.


I have my hands full, to say the least.

So, I am anxious to hear what you guys think? Also, if you have any questions, please ask.

Thanks guys!!

Cool, nice install. You did a great job of making it look easy.

Years ago I built this one for the track. Only pic I have though.
I stretched the custom glass front end, tube frame, engine plates, 454 W/PG tranny, 9" rear.

Did you have to custom fab the headers? Didn't see a pic of them...but looks like a VERY tight fit.

Maybe we'll see you at Famoso? There was a Z car that used to run there, Jon Peters, I believe his name is, from my hometown of Visalia. He ran in the 7's. He's now building another car for the strip, I'd love to get his Z-car. You've got a cool project, keep us posted. Big motors in little cars, gotta love them. Dan

Yup, the headers are custom made from a pair of hedmen headers (cut/bent/re-welded). They are an extremely tight fit on both sides of the motor. The frame on the passenger side and the steering shaft on the driver side. If I had the motor sit any further down they wouldn't work at all, but I wanted more hood clearance and a lower center of gravity. I didn't want the whole car swaying because of the heavy motor mounted too high.

I've tried to pass Famoso's tech and they won't let me run without a roll cage. They don't like IRS and any amount of HP/TQ together in the same car. Its understandable from their POW.

So, until I bite the bullet and find a shop that doesn't want my car to sit there for months until they decide to get around to installing the cage (at least a 10 point tied into the engine strut towers), the car won't be running at the track.

The funny part is I highly doubt the car will go faster than 12's due to my extremely limited traction. I currently have an open rear (I have a posi, but I am $1000 away from installing it) and combine that with hard street tires. I can't even floor it in first gear, at any speed without blowing the tires away.

I am sure the car will be considerably quicker with a cage to keep the body from flexing so much, posi to get it to both of the tires, and slicks to get it to the ground.

Stock, those cars never especially interested me. But your's will be nice! And it looks real good.
I had a friend who put a 340 in a 260Z once, that was a fun little car. The same guy now has a radically customized and modified MGB with a built 440 and dual quads. You would be very hard pressed to identify it as an MG.
