It was two years ago today I went to collect my Hawk 289…now it is better than ever!
The last two years has seen the car evolve into a great car, so here's an update of what I have had done to it.
Some of these upgrades have been detailed on other threads...
It is a 1967 HAWK 289 FIA, first registered 20 June 2002.

It has rear leaf springs each side with uprated lever arm shocks and MGB GT axle and diff. The Front is MGB with uprated lever arm shocks , but has the Hawk disc brake conversion.
The original builder/owner of the car replaced the originally fitted RV8 3.5ltr he fitted with an RV8 5litre engine.
It was taken from a TVR Chimera, but is also used by Morgan +8's. The hot-wire efi was replaced with a 4 barrel carb Edelbrock 500cfm 4 Barrel.
It has been set up for fast road use, so at 70mph it revs @ 3150rpm.
The 5 litre engine was professionally stripped down and fitted with the correct pocketed pistons for the valves and stamped up 5L on the pistons. The heads are all TVR and have the largest size valves possible for the standard heads. It also had extensive work done to the inlet and exhaust ports to stage two spec. Standard valve springs were replaced with up-rated ones along with the guides and were ground back to the seats.
The 320-340bhp that TVR quoted for the engine never really existed. I understand TVR took the 3.9 RV8 engine out to 4.3 litre and also to 5.0 litre for the Chimera by fitting a "stroker" crank and high compression pistons. Bore remained the same at 94mm, but the heads were fitted with larger inlet valves and the engine fitted with a performance cam.
It was originally quoted by TVR to produce well over 300 bhp, but it's generally thought that their dyno was not calibrated correctly the day their engine was tested.
The engine fitted to this car was tested on a rolling road at Austec Racing - TVR specialists and produces 250bhp and could be tuned with the existing carb to 285bhp.
The fitted TVR swirl pot has been removed with the cooling pipes re-routed. The land rover expansion tank was replaced with a period looking aluminium one I also replaced the Rover Valve covers with "Cobra" ones. The coil, ballast, leads and OPUS 35DLM8 Lucas distributor (as fitted by TVR) have been replaced. As the OPUS type tends to give trouble with misfires, especially with a hot engine so I decided to have a Mallory Magnetic Breakerless Distributor with matching coil and ballast.
(for info: The OPUS Lucas 35DE8 was used on the Rover SD1 engines from 1976 - 1981 and then replaced firstly by the 35DM8 and then by the 35DLM8 on the last of the cars 1985/1986)

The hubs have been refurbished, seals replaced and polybushes fitted all round. It now has ant-tramp bars and a pan hard rod fitted.
