would this engine bolt on to my 1980 series 3 gearbox and into my series 3?
Thats what I wanted to do with it (same year Series as well!), however money is not available to buy it the now.
There are people who have done it, but the main question is what the bellhousing pattern of bolts is because the LT77 had 3 different bellhousings, V8, VM and Tdi.
