Sorry about the 337s. At that time in the 70's we or my father went to
352s or 390s and one with a 430. As you may know a 390 391 flywheel
bell housing starter will slam right on a 383 or 430. And as for whats
left is the F6 service truck he bought new (239). So now we run with
the F6 3 F900s 1 F800 and the 10 wheeler im still try to find an alum.
15' used dump. Ill keep my eyes open for a 337 head and also one of
my F900 has the truxmoore setup but I have no info on it. All I know is
this truck was born and raised is the Boston area so I suspect sombody
around there was a Truxmoore dealer. Till now I still dont know why
this setup is better. Just looks like overdone dragmasters. Any Idea. sam
