For your consideration today is used Holley Secondary Rear Metering Block 4519 GM Factory Carburetor. This block will need a good cleaning before use! 

 

My shipping prices are based off of what I have learned over the years that items cost to ship and most times I lose a little on shipping. There is no such thing as free shipping, shipping will either be paid by the buyer or the seller will take that much of a loss on the item to ship it.  Shipping is expensive no matter who the carrier is and please understand this. I do not charge for packing materials or boxes and the majority of the items that I use are recycled as it just makes sense to do this.
