Well,after nearly 5 years my 87 D150 is up and running again! ‘89 360 with a whiplash 318 hydraulic roller cam,stock internals and a set of reg 360 heads( the 308’s were trash). The extra cubes tamed the cam a lot but it still has a lot of snap on the bottom just like i wanted. Mated to a 727 with a boss hog 2200-2800 converter and a 3:55 sure grip.
