Why would anyone do this swap when you get just put a 4.25" stroke crank in with new pistons and have a 8.1L without any swapping or issues?
harness and engine take out, 411 swap
full 01-02 3500hd parts truck
they don make intakes and cams to run dizzys on an 8.1 but waste of money to revert back into technology.
theres probably a handful of other ways to do it if desired.
Are you sure about that? The Vortec 8.1 was GM's last engine they produced that will take an HEI when converted to carb.The heads will not bolt on there is no provision for a dist. In an 8.1. If your gona do it swap the whole engine everything is impoverished over the previous gen big block. Everything. Pass lock is easy to tune out that's not a big deal.
