    Whoops - forgot that I posted in this section. Thanks for the replies.

    I ask only because I already have a GM 161 in there, and was wondering how careful I need to be based on whether the drivetrain was developed to handle the 2.6 6 cyl. I found these figures, so I don't think its as much as a risk as a 186 or 202.

    Rover 2.6 - 67kW @ 4500 , 178Nm @ 1500
    GM 161 - 81kW @ 4400 , 198Nm @ 2000

    The gearbox is the weakest link. 6cyl and 4cyl are the same where it counts (layshaft, gears, etc...) - so strength is the same.

    The 161 in stock form is not hugely powerful, so it will probably be OK, however there is a chance of breaking the layshaft or stripping a few teeth from 1st.

    AFAIK the earlier boxes were weaker, with the last 2A, the F suffix being the strongest. I broke an early box's layshaft, the one with the dipstick, with a 202 engine. I replaced it with a 1969 F suffix box and dealt it a suitable thrashing with said 202 and 35 inch BFGs with no problems.
