if u do a V8 conversion to say a 91 patrol ...
what are the laws with what type of engine + emission laws and all that


can i dump say a carby 351windsor or clevo into my 90 model patrol?

Generally the rules are as follows. (And i do say very generally)

1.) The engine must be same age or newer than the car and must be installed with all required emissions add-ons.

2.) Any engine can be used but must be straight gas, ie no duel fuel. just gas.

There is a 3rd option but requires emissions testing which is just not worth it.
