Anybody have a rough idea of how much it would cost to get one running in a 240z? What shops in northern cali can do this or have done this? if you guys have phone numbers that would be helpful. thanks

 

dude
your car is more valuable with the stock engine
but...
an L28 in a 240!!!!!
make sure your frame is plenty strong for the increased torque that the L28 will make.
what do you palan on doing with your z? street driving, racing, drag racing , or show?
For the info the older the early z the less metal that the car has.
Your 0-60 will be sweet with the awesome power to weight ratio.

And then you will need better brakes...
then better tires to stop with...
