The original 1600cc engine was removed and the Alfa upgraded with a naturally aspirated 1750 twin-cam inline-four taken from a 1750GT Veloce.
It won’t surprise you to hear that it was completely rebuilt with a new 80mm piston and sleeve kit, a set of Victor Reinz gaskets, new standard main bearings, and a replacement bottom chain.
The crankshaft was also polished, the cylinder head was renewed, the oil pump was fully serviced, and a new water pump was fitted.
The five-speed manual gearbox was also stripped, checked, and repaired where necessary and fitted with new front and rear seals.
All the components were powdercoated, and we are told that new suspension and brakes were fitted.
The car’s fastidious UK owner sent it straight to Peter Smart Classic Alfas in Dorset when it arrived here to be serviced and checked over.
The service was a full one and included changing the engine oil and filter, filling the gearbox and differential with fresh oil, fitting new sparkplugs, and draining and refilling the coolant system with new coolant.
They also carried out a full check over of the vehicle, and a compression test revealed 175 psi across all four cylinders.
Nonetheless, despite being assessed by them as being “very nice” they felt it would benefit from some further tweaking. This comprised the carburettors being stripped and refitted with aluminium mounts, new gearbox mounts being installed, the correct rear exhaust put on, and having its suspension Polybushed.
This work set him back £1,666.49 and the invoice is on file.
It’s since had a full ignition service with new ignition coil, HT leads, points, condenser, distributor cap, and rotor arm – plus a new fanbelt and speedometer cable – and as you can see in the video, the 1750cc engine starts and idles and runs as it should, even from cold. There's also a new battery.
It also sounds terrific on the move with a lovely induction note from the twin Weber 40 carburettors and a suitably fruity exhaust.
As for how it drives, the seller tells us that “the engine pulls strongly with plenty of power and the gearchanges are smooth. There are no squeaks and rattles, and the car handles very well.”
The engine bay is very nicely presented being clean and tidy. We can’t see anything in there that would bother most owners, and all it needs is a wipe over with a clean cloth now and then to keep it looking this good.
The underside is just as nicely done. It’s been finished in a mixture of paint and underseal, with the wheelarches and sills left in Giallo Ocra to enable you to appreciate the quality of the finish. The rest of the undercarriage is well protected with durable black underseal.
Some chunks have been taken out of the fins on the oil sump, so perfectionists might like to budget for a replacement. The rubber sleeve on the brake master seal has split too, so that could do with being replaced while you’re under there.
