Datsun 240z V8 conversion



So i have decided to go ahead and do a carbureted small block chevy swap into my series I 240Z. As always i will be doing all the work in my garage with the help of friends.

First My motor:

I'm hoping to get around 250+hp and 300tq at the wheels.

freshly rebuild Chevy 5.7L SBC 350.
4-Bolt main
Block has been bored 40 over
An excellent set of 882 heads
Edelbrock RPM airgap intake
Holley 600cfm carb
New Comp 268 cam kit.
New flat top pistons providing a 9.5:1 compression ratio
M/T valve covers
New Black Coated Steet Rod Hugger Headers





Second Transmission:

I will be using a World Class T5 out of a 5.0L mustang. I have rebuilt the transmission and done a few upgrades to build in a lil extra strength into the T5.

New shift forks
New shift fork inserts
heavy duty cluster gear support plate
New Input Shaft/4th Gear Bearing & Race
New Output Shaft Bearing & Race (85-95)
heavy duty input Bearing Retainer



Third Chevy SBC to Ford T5 Coupling:

In order to couple a chevy motor to a ford transmission i an using the bell housing for a chevy WC T5 transmission and a custom adapter plate.





Fourth Clutch:

Again to run a chevy motor with a ford transmission i an running a flywheel and pressure plate from a F-body camaro and the clutch is from a 5.0L ford mustang.



I'll be using a JTR kit for the engine mounts etc.



I have the drive shaft from the mustang and once i get the engine and transmission transplanted into the car; Ill get a final measurement for the drive shaft and have it cut and balanced.

I got the hood and the exhaust off the car to get ready to pull the old 2.4L L6 motor.

I've done 2, a '71 240Z with a 355 / TH350 and a '74 260Z with a 355 / 4 spd. Both of these were a long time ago but I had a lot of fun with them. Obviously the 4 spd car was more fun going through the gears and the engine was "breathed on" a little more. I did remove the hood latch on both of them so I could set the engine back and up a little, required hood pins but that wasn't a problem.....have fun with it.

Being I am an inline six nut, and those cars are piece of my youth (I literally rode to the dealership on my Stingray to look at them in the showroom) I would have a very hard time pulling that motor out.

That being said you are making one awesome hot rod! I LOVE IT!

I have a 280z 2+2, fun little car. The sbc will be a lot of fun. I'm building a chevy 302 to drop in mine when I get around to it. Where did you get the plate to mount the ford t5 to a bellhousing? That would really help me out.

The crappy 882 cylinder heads are going to ruin this beauti project.

You can have so much more performance with a real hi performance SBC cylinder head.
Find a better head. Something like this.

You can have a supercar instead of a dud.

There is no such thing as a excellent 882 head. They are the worst cylinder head GM ever made.

Well I eventually will upgrade the heads with a nice set of Aluminum heads but for now I'm just going to enjoy the new motor. In its current spec i think i should be able to get around 250 -270hp at the wheels; That is more than double the HP of the original 2.4L motor. Should also get a healthy boost in torque over the stock motor. Also my diff has 4.11 gears in it which will make this a quick car. So for now I'm just gonna stick with the 882's i got on there.

I had a friend make it for me. I gave him my transmission and the bellhousing and he did the rest. I could have him make another one if you need it. it would be $120 + shipping.

Finally got the SBC and T5 dropped into the 240z. The entire motor sits behind the front cross member. Next step is to get the motor plumbed and wired; also need to get the drive shaft cut and balanced.

If you find a Chevy Astrovan or Pontiac Safari bellhousing the Ford T5 will bolt right to it without an adapter. Advance adapters also builds an adapter to make this swap possible if you can't find one of those rare bellhousings. Lakewood also makes a scattershield bellhousing to do the swap.

Today i created some homemade fuel lines my car; the design has a return fuel line that ties into the OEM return lines of the 240Z.... hopefully it works as intended.

Also installed my beloved monte-carlo bar.

Nice looking build! A friend has built 4-5 of these, his personal car has a crate LT-1 in it and is a rocket ship! Mileage is decent, not a terribly hard build, many parts are available for the exchange. Keep us posted. Dan

Will an air cleaner clear the support bar? Looks pretty close to the carb from the pics.
