Welcome to the forum! The best way to get help is to first use the 'search' function in the forum. This will help you get the information you need regarding the swap. Also, I'm pretty sure that MSA sells the parts for the swap, if you don't want to fabricate your own. Good luck! icon_smile.gif

83ZX350:

I just got an 83 SBC conversion on the road less than a week ago that I started in Feburary this year. (Now I are one)! Still have a few things to sort out, but it looks "factory", has around 430 horsepower and will undoubtedly be very fun, and a great metamorphosis of a car I've had and pampered since day one! I'm not a mechanic per se, and the only things I "contracted-out" were the driver's side hedder modification, exhaust fabrication, driveshaft modification, and the hood scoop! Everyone would tell you to read/re-read the Datsun Z V-8 Conversion Manual (http://www.JTRpublishing.com). The philisophy should give you enough confidence to take this project on, but many of the "tips" do not apply to the ZX, starting with the motor mounts. I have a 17 May post (ZX SBC using MSA mounts) that might offer some help. (As it turned out I didn't need/use the painless 700r4 lock-up kit, but everything else is pretty much the same). I'd be happy to provide whatever help I can. There are a couple of other "ZX" conversion guys who have lots of experience and will help you out!

My first piece of advice (if your car is solid)is to get a 1983 280ZX service manual (Haynes in comparison to the factory manual is dog-shit in my opinion)

and label all the wiring as you dissassemble the L28 fuel injection harness and accessories. There are tons of wires you don't need, and it would be a nightmare to sort out unless you speak fluent "Z" wiring. My wires went to the right "places" witout a problem. The only thing that isn't working is the temp gauge and I believe it's a bad sending unit. The range of dollars you spend on this conversion is as wide as your budget will allow. My "ending" engine configuration isn't close to what I had envisioned at the start. Whatever your budget, plan on spending more than your first vision. Guess the important aspect of this whole thing is to think a lot about what you want the end result to be, ask a lot of questions, and be realistic as to how much money and time you are willing to commit. Good luck!

HEY I WAS WONDERING IF ANYONE HAD EVER DONE A CHEVY V8 CONVERSION ON A 1984 300ZX. IF SO I WAS WONDERING WHAT KIND OF MONEY I SHOULD BE EXPECTED. THANKS IN ADVANCE.

I got my 83 converted about 3 months ago.It's a blast. I used the Motorsports mount and a 700R4. The biggest problem was getting pulleys, I used a surpentine system off a 93 Caprice. Headers were from Sanderson (They clear the steering box). Stock Radiator (Not big enough thank God it cool right now in Texas). Electric fan Black Max,600 cfm Eldebrock with a performer mainfold and lots of time and cash. It really roars with the dual flowmasters and the comp cam. Driving has not changed much except thngs happen much faster. You will need a hood scoop if you use the motorsports mounts.
