here's my boss 302 clone that may be going in the bronco if the 351m is trashed
nodular iron crank
scat rods
speed pro pistons
summit cam .563"/.588" 234/244 duration, probably more duration with the 1.73 rocker arms
pro-comp gear drive
D5 351c/m heads
and I got an Offy dual quad on there, but it probably won't go in
i might put a smaller cam in, thats probably to much cam for a 4x4
