Probably been asked a million times before, but for SVA declaration and for correct speed-rated tyres, what do you reckon max speed would be for a 7-esque car with 2L pinto, standard type 9 box and standard 3.62 diff , 14 inch wheels?

when i sva'd i ran 2.1 pinto with R1 carbs with 3.62 diff and i submitted 120mph

I put 120mph with a red top on twin 45s with 17" wheels
Its all down to the speed rating of the tyres!!
my tyres are rated upwards of 150mph

Most people put around 120

Great, thank you

just make sure you're tyres are rated for 120mph

And the trousers rated for washability ?

Ty Butcher that was part of the reason for the Q. I think I might try for 130 tyres
( marked H ) just to be safe.
