Inside the boot should be body colour
Had 2 and both have been black under side (underseal)
The 2.4 is the lesser Engine , but should run ok , and should run at 80mph all day
Not sure about Km , but 2.4 had 120 speedo and 3.4 and 3.8 had 140 mph speedo’s
If Engine is locked , go in at a very low price , then fit a good 3.4 engine in
I bought my 1965 MKII with wire and OD when I was working overseas in the U.K.
During that time I bought 3.8 springs with the plan on “upgrading” the engine to a 3.8.
The engine I built for this was used in another one of mine after I decided I really liked the engine. Yes it could be quicker. The previous owner has obviously changed the rear end. The engine is ticking over less than 2000 rpm at 65 mph, which explains its lack of urgency, but it cruises great and sound Ike a sewing machine.
I fitted triple 1 1/2" SU’s, but the sole exception were fine, I was bored when I did that. I miss the oil bath air cleaner.
Heater sucks, even after sealing everything up, might address that if I do AC tht should slower me some.
Have no idea what the color underneth should be but mine had undercoating and sprayed body color.
