Bear in mind that the later aluminium bodied Mk IVs were made by AC Cars and beautifully built. That is Autokraft owned AC Cars as opposed to building them under license. They were sold as new cars and there is not likely to be any future challenges to their status. There are around 11, Mk IV 427’s and one of those over a continuation, were one available, might be preferable for some.
You have to have certain make up to be a long term 427 owner and very few have that DNA. That’s important as the cars are near impossible to sell privately, or p/ex for anything like what you paid. The cars with original iron engines are very front heavy and Shelby himself called it ‘The Turd’ and stated it needed a aluminium block. That wasn’t available in the mid sixties, so development ended fast.
Anything over 400 bhp is very hard to hook up (drive fast) with anything approaching the security of modern performance cars. Some find the scare factor part of the excitement, others soon realise they can’t live with the unpredictability and quite frankly, danger.
The base Mk IV is unlikely to frighten you at all and the so called Lightweight is a good compromise. But for some, they need the thrill of attempting to master the spellbinding big block 427. Lewis Hamilton owns two 427s and I’m pretty sure Michael Schumacher bought one upon his original retirement.
The most coveted big block engine is the 427 side oiler, not the 427 top oiler, nor the much less powerful 428. Make sure you are buying what the description says you are.
But really you need to be sure you are one of the few that will love the monster 427, long term.
