so i have lots of electrical gremlins with my motor so i want to change harness and motor what would you say the best swap for wheeling is I am capable of doing almost all swaps ive looked into

the 4bt swap
cons
new fuel system
low revs
pros
lots of torque
unique

5mge or 7mge
cons
posible cut of radiator support
might not clear ifs
change whole harness
pros
high revs
turbo possibility

350 or 4.3
cons
bad mpg
not to unique
pro
powerful

now idea about the buick v6 seems useless

is there any other motors than can be swapped in easily?

 

Someone's doing a Volkswagen turbodiesel swap on here; search for that one...it's pretty interesting.

 

What motor/ tranny do you currently have?

If 3.0 V6, a 3.4 drops right in.

Same motor mounts, same 3.0 radiator, same bellhousing, same fuel supply lines.

Relatively easy swap for a good and strong TOYOTA motor.
