My old 1380 with 286, Longman gt15 offset valve head, 3.44 FD & S ratio box was fine on the road, it used to be my daily driver in moderate traffic. On twin hs4's it was drivable from 1800 rpm but started to come on cam at around 2500 and would rev to 8000+

My current 1380 road car runs a 649 based cam, same carbs, 37/31 offset valve head, SCCR box and 3.9 FD, its unhappy below 3000rpm and a real pain in traffic but massive fun on the right roads.

 

Daily driver! Thats quite peppy for a daily. How long did it last before rebuild was needed?

Used it for 7 or 8 years as a daily driver, engine and box had numerous rebuilds during that time, something was always breaking, mainly the diff pin.
That engine was in there for 25 years but it was a bit like Triggers broom!
