Riggles , I'm still using the Carter w-1 from the original 216 . I have adjusted the fuel pump shot a bit , it runs strong , but I tend to drive my truck a bit like a diesel ..... kinda 800 to 1800 rpm . With the '56 diff (3.9:1) and the tall tyres , I find 2200 rpm at a bit over 50mph within my comfort level.
