1973

The Competition History of RAD 366G - Marcos 1600GT :1968-1974

Timeline on technical events (1973):

I find am unable to find notes on any work that Stan and Tony carried out over the preceding winter. It`s well possible that we decided not to progress further with development work as this would involve major expenditure i.e., Steel crank etc. I was happy with this arrangement as I considered that the car was going quickly enough.

One step forward was the use of slicks whose grip was amazing. I also bought from Roger Andreason some specialized wet weather tyres all as described below.

Later in the Summer we had a more serious catastrophe in that the Crankcase block split. New one required.

Tyres:

Slicks.185/550 13 D22 370 compound on 8"rims at front.
 200/550 13 D22 370 compound on 81/2"rims at rear.
Bought 12.3.73. Used to the end of racing with, I think, a second set later.
Andreason`s wets were bought in summer of 1972. 425/950 970. One is different.

 First race of the year with Practice on a damp track but a dry race to follow. My race notes say that oil pressure started low but recovered. Sunshine roof failed and the rear screen broke. Not a promising start.

 An amazing day and in Practice I achieved my best ever lap time of 90.75 mph. We were on slicks. Race conditions were wet sadly.

No further info.

Did not start

 Our non-start was almost certainly due to engine block problems. See notes on next race.

Pitted on 9th.

 The coolant loss mentioned in the notes of the race at Combe earlier developed into something more serious.  The crankcase block split. Unrepairable and a new block was required. No more racing that Summer.

 Back in business with a brand-new block. The race was merged with the GT class of quicker cars. We put up decent Practice and race times to make it a good way to finish a troublesome year.
