Chevy 350 SBC 1971 240z Conversion

Recommended Posts

Hello, I am looking for advice in doing a Chevy 350 engine swap in my 1971 Datsun 240z. First, I would like to know if there is a conversion kit out there for purchase somewhere. Second, what kind of engine mounts work best for this kind of swap? Also, if anyone can shed any light on information they wish they knew getting into this I would really appreciate it. Thank you in advance for your help!

  • Buy the JTR Datsun Z V8 Conversion Manual from  http://www.jagsthatrun.com/index.html      Read it at least five times.

  • Buy the book How to Restore Your Datsun Z Car by Wick Humble. It will save you hours of searching for "how to" info.
  • Focus on searching Hybridz as 99% of questions have already been addressed.
  • Start bookmarking Z car parts suppliers - there are many!
  • Remember these are 40 year old cars and will need restoration to be safe and drivable.
  • Join ClassicZCars.com website and search there as well.
  • Become well informed about modifications before asking questions. People will be more inclined to   answer informed questions.
  • Search the Hybridz forums.

There are three install kits available:


  • Jags That Run (JTR)
  • Motor Sport Auto  (MSA)
  • Johns Cars

Each has its own pros and cons. Driveshaft alignment is critical for all of these kits. You can research each one at HybridZ and Google search


All of the kits assume that you have some automotive mechanical skills.  If not done correctly these cars can kill you,
