trying to see how much everybody would think this motor would cost.

350 out of 87 trans am with 25k miles
stock bottom end
edelbrock 750 cfm carb, with tuning kit
edelbrock air gap rpm intake manifold
Trick flow heads with upgraded springs (195 cc runners)
crane gold roller rockers
trick flow pushrods
edelbrock alum water pump
edelbrock upgraded fuel pump
MSD dist
upgraded hyd roller cam

Probably around $1000 - $1200. Used motors don't have much value unless they are something special.
