I grew up on an '87 Scottsdale withe the pre-vortec 4.3/700R4 in two wheel drive. For being an underpowered slug with no front assist, it did A LOT of work for Dad and I. Even rebuilt, that engine was only a "townie" model, and with either 3.55 or 3.73 gears, it didn't do well with trailers... Now, if it would have had either a 350, or a well built 265 or 292I6, that would have been different. 305's were ok, but not much better than the 4.3, in a work truck, in those years. I'd take a Dodge 318 ANYDAY over them.
