The MGC was a case of shoehorning a tuned six cylinder 3 litre BMC engine into the MGB shell, but with fairly extensive re-engineering. The MGC used the same specification 145bhp engine as had been used in the big Healey. A new torsion bar front suspensin was required only because the engine would not in otherwise. Management had planned that the MGC would take over the mantle of the big Healey which had come to the end of its production. The MGC was available in both roadster and GT versions, with its distinctive bulge on the bonnet. But the MGC had quite heavy steering and for whatever reason was fitted with drum rather than disc brakes to the front wheels. The MGC got some very mixed reviews in the press and although introduced in 1967, production was was finished shortly after in 1969.

MGC tyre size: The MGC was fitted with the larger diameter 15" wheels and came fitted with the 165R15 tyre size, which for interest was the same radial tyre size that the big Healey was fitted with. Today many of these Healeys run with the 165R15 size as standard or use the slightly wider 185/70VR15 size. And similarly for the MGC, our high speed rated steel belt construction and period correct tread pattern 165VR15 size Blockleys is the correct fitment and will work perfectly. We also list the wider but same diameter 185/70VR15 tyre size, for those who want the non standard wider (but same diameter) tyre, so we show this also below. Our Blockley tyres will transform the handling of the MGC - guaranteed. See full details of these MGC tyres at the links below:
