Get a crate motor….
For example:
I recently saw a sale at JEGs for a 230 HP 350 for $1300 and change with FREE shipping. Perfect for guys who don't want or can't do the work themselves.
Maybe, Have it sent to a friend at the border …?
At that price ANY warranty is a bonus.
As others have stated you'll have
1200+ in machine/valve train/head work Before you start throwing parts at it.
my 2 cents
