is my car in any way special/rare or more valuable than any other? 70 340.

Hey Guys,
I recently bought a 1970 Dart Swinger. It does have the 340, and the VIN tag decodes to a 340 car.

It is not stock... it was originally a manual car, but a 4 speed has been swapped in.

The car was repainted from yellow to maroon... still using the same block but it has J heads and a 6-71 blower with dual holley 600s. Came with the stock hood - unmolested, seperate.

I also don't have the stock wheels and am rolling on a set of 20s with a Pro Touring theme.

I recently read somewhere that the 1970 340 was somewhat rare... I honestly do not know so I thought I'd ask. Below is the VIN... it is a Canadian car.

LM23H0R232980

Also... the rear bumper has a pair of rubbers bumper things on it that I see some cars do not have.. are they easily removable... stock??

I suppose the other reason I am asking is because I have been planning on shaving the side markers, handles, antenne, etc, and doing a pretty crazy custom Pro Touring Rod.

I'm not for molesting an original 340 Dart or any other mopar unles the mods are period correct. I think the "pro touring" thing is destoying the culture.
