Hi Scott The AMC 258 Replacement Jeep Engine and all the engines were from certain modle years and had different heads and blocks used. The VIN would be needed to determine the engine needed and availability. Thanks

Is this the full assembly or just the block? I have head, crank, and fuel intake assembly, all I need is the bare block. I Wanted to see what all was included. By the picture it appears it's everything but the fuel intake. Can you please let me know what components are included in the price or if I can order just the block by itself, block with pistons and crank, block and pistons without the crank, and if so what are the prices.

Asked by Stephen from Conroe, Texas on

Stephen, the ATK NORTH AMERICA AMC 258 Replacement Jeep Engine is a long block so it's a fully assembled engine minus all of the tin parts, intake and exhaust manifolds and the front running gear. That's the only way that these are available through us is fully assembled. Hope this helps!
