His is a 4.3L.
Poor tuning methods did his blew his head gasket. Good thing though, with all of that built hardware in there, it is easily rebuild-able.
There have been others to buy built engines from URD
and LC Engineering. Those are all running strong, as long as they have been properly tuned.
I have only one component in mine that others in the States don't have. Nothing to special, except that they are almost harder to find than a unicorn. My custom Kelford Cams.
If you are going to get an engine built, either send yours in, or have them do all of the sourcing and work for you. It will save you loads of headache.
