Yes sir, plug and play.
No need to "lock anything out", it comes ready to go.
Interesting that Rover V8 owners are converting to HEI because it is so reliable.
HEI is an OEM factory component of all but the very early inline Chevy 6 engines.
GM hit a home run with an engine that requires very little maintenance, it even has metal timing gears instead of a belt or chain.
For those of you building or having an engine built, use the Comp Cams 61-232-4 for plenty of power and smooth performance in the 2400 to 2500 RPM range.
I have told everyone to stay away from high end racing cams with a rough idle that will operate in an RPM range that will never be reached in a Defender.
When I started building Land Rover conversions in the 1990s, designed a cam for the GM 3.0 liter 4 cylinders that Comp Cams would grind for me that worked well, but required a few dyno run comparisons to dial it in to reach a final design.
It's nice to skip all that with the optimal cam available off-the-shelf for short money.
This one will perform better than the original, but keep close to stock.
It was often called the RV cam in the past.
