It's almost my birthday ( parts time)

As the post said it's almost my birthday and the wife said she was going to buy me something for the car since I have been out of work for a while .....You know just to get my mind off of the crazy stuff I can work on the car...Anyway I want and need a gear drive set up for my small block..and yes I need one the block was align bored and the chain set up is just to slack for me car never run until it was out about 60/100' so I think the gear drive will fix the problem...now ? who makes them besides milodon and how much and who do you like the best ( I think I know) but want to here from the mopar nuts.......8)
