    * For those deer hunters that just looked up from their hunt to realize race season is just around the corner! This is an assembled short block manufactured and assembled by Dart. They are well assembled trusted race engine short blocks. With good heads these can make 750-800hp N/A. Free freight until April 1st.

    * For those in need that can't wait on us... these do not have pop up pistons or custom parts (no substitutions) but are good overall race engine parts with a quicker turn around. Don't dismiss these due to the flat-top. These can get 12-13.5:1 compression depending on heads & deck clearance. We can also get down to 8.5:1 for power adder guys
