the engine that you are talking about is . The GM #12568758 its a 87-95 LIGHT TRUCK 350 two bolt main . It does have hypereutectic pistons with 9.4.1 CR .Also uses a high volume oil pump and a flat tappet hyd cam . It is 200hp/300ft/lb of torque . I was thinking of using one in my 1989 1500 Chevy . You can run a TBI or a carb . And it does have the hole for the mechanical fuel pump . You can buy these engines from Chevy or summit/jegs . This engine cost around $1730.00 A cheap intake to use on it to run a 4bbl is . The Professional Products Cyclone intake #52001 . This intake has a set up with adapters that fit in the center holes . This make it possable to run this intake on early or late heads . And its a Dual Plane with a cost of $109.95 I think this is a good engine for the money .
