Hi Al,
Would this be the car I remember from my younger days called the Invader ? Alot of people won't agree with me on this but my personal opinion is that such a car should be preserved in original spec....ish...
I was looking at tuning the 3.5 in my factory BGT, but with not many mods you soon reach the kind of power that in all likelyhood will knacker the original 4 speed plus o/d on fourth gearbox. So I'm thinking, OK, put an LT77 in it, problem solved. Then I think hmm, with an LT77 I can have even more power ! This is then a case of do I really want to bother rebuilding and tuning my old 3.5 (very limited for a number of reasons) or do I go for a 3.9.. etc etc. Anyway, before I become boring (which I probably have already), I decided to keep the old girl factory original, with just a few tasteful mods, all of which can be reversed if you wanted the car back to totally original.
If it were me I think I'd be inclined to go along similar lines with the Gilbern.... Must be alot of reversible mods you can do to improve performance and roadholding etc without taking it's (ish) originality away.. Is it the 3 litre Ford engine in it ? How about a rebuild and a supercharger... keeps it kinda period but alot quicker
Anyway, I agree with your thinking and you're certainly no mouse, In the case of some cars I believe we have a responsibility to preserve them for the enjoyment of future generations....
