It all depends on you. If you like your car, keep it and get a long block with a blower. If you would like to sell it (sounds like you have a big interest in the cobra's), you can always get a 99 cobra, but then again your insurance would go up. Its all up to you. I think If you got a long block with a blower, your currently car would be a really fun car to drive
. My 2 cents.
