Can anyone confirm the curb weight for a 1980 242
1290kg or 1320kg or 1338kg or +?
Hoping its 1338kg for mod plate reasons....
65kg is quite a lot of weight, particularly if you're putting a lump of it forward of the centreline of the front 'axle'.
How much of an impact it'll have will vary depending on where you position it.
The Ford I6 is long and tall, the additional length and mass needs to go somewhere.
It'll never be as nimble or as happy to change direction as the car would be with the B2xx in it, but maybe that isn't too important and the increase in power and the desire to venture the road not traveled has it's appeal.
Working out spring rates, etc will be best achieved with a set of race scales.
If you haven't got access to a set, you could get in the ballpark with some guesstimation.
Drop me an email if you want to bounce some ideas around in this regard.
