His car is a street car. That motor has been in his car for at least 7 or 8 years.
I don't want to give you a bad taste for 427s. His motor was built by a well known builder, but had issues. Some were due to the machine work, some were cheap parts, his cooling system couldn't keep up. He broke rockers...went through a couple cams and a crankshaft. Every time he'd go through the whole motor. That thing has seen a lot of different sets of all kinds of stuff. He even had an issue with a high volume oil pump that starved the motor...all the oil went to the valve covers faster than it returned to the pan.
That car has made 10hr trips to Mustang Week...but its always had something going on. As far as I know he hasn't had any problems with the trans or rear diff.
I've heard of guys running them reliably but I don't, personally, know any. I do know a few guys running 408s and 393s.
My friend , Sam, is 64 years old so he's not the type to tear ish up anymore. He's just had a bad stroke of luck with that motor. Its like a sickness he just can't shake. It'll run great for a couple of months and then BAM !!! It strikes again. I understand, 427 is custom painted all over his cars hood and fenders but jeesh. Out of the 7 or 8 years its only been running a handful of summers.
