I was told by the owner that it was an R block but the part number didn't match up. The owner said it was an R block with W9 heads but I'm thinking now that it is an X block with W5 heads. No guessing about the heads, they say W5 right on them. Block will have a huge X on the left front side( if looking at it from the front of the car) if it’s an X block. Otherwise it’s just a 318. The X and 318 do both come with same bore size, 3.91 69 Dart GTS A4 Silver All steel, flat factory hood, 3360race weight 418 BPE factory replacement headed stroker, 565 lift solid cam Best so far, 10.40 @127 1/4 1.41 best 60 foot 6.60 at 103.90 1/8
