Ok I have brought up the question more then once on this forum on why not overdrill the 6.0
I just finished watching Car Fix and they are taking a Cadillac Northstar 32V 4-8 cylinder engine and over drilling the head bolts. They actually used a hand drill to drill out the threads in the block. They used two sized drill bits for the process to keep the holes straight.......hopefully.
Then they re threaded the block for the bigger head bolts. They are using ARP fasteners for the engine I see but went no further on the job in today's episode.
I learned the main bearings are also TTY bolts, not sure if they are going to upgrade those to ARP or not but will surely finish on next weeks show.
They showed no work on cylinder head drilling but I am sure they will at least use a drill press or mill.
Anyways I'm stilling waiting for someone to do this on our beloved Six-Oh. I am waiting to see the rest of the job, but at least my way of thinking is not a impossibility. Toren you are the one on this forum that has the most experience with our engine. I'd sure like to see you take on at least one and crank it up to 1,200 HP and see how it does.
At bare minimum I can see it being done on a Cadillac engine.......
