Hello Coach,
Here is an owner who has installed an l98 vette engine into an Amigo. Just might be worth a call to the owner to see how he did it.
L98 Amigo

Which company did you go with the electrical wiring?

I here
Speartech
is one of the best painfree wiring harness for the LS1 conversion.


Glad to see you back!

Cheers
