I have a 283 i put in a truck with plans on driving it but i bought a camaro and have givin up on the truck, we only drove it twice for a total of maybe thirty miles, bored .40 , flat tops, edelbrock performer intake and 600 cfm carb with electric choke, also a set of lt1 heads(the old cast heads) headers, but they are block huggers, this is a great running motor and hate to sell but need money for camaro and hate to just see this motor set.
