[Agv63]

When i got my 63 it had a 250 with 3spd saginaw, 3.73 and 31/10.5r15.
Pulling away on was not a problem, can chirp the tyres and cruising was decent at 120kph (75mph) i calculated roughly just under 3000rpm ,no tach to verify just calculated from tyre size and gearing. still had original but sagged springs in it. Some pics included.

Cheers.
