i have a couple single pulleys if need one or maybe you already have one just trying to help plus anything else you could think of for a h series lol. I had a buddy about eight years ago run a h (with shitty h trans ) stock with a 74 shoot in stripped eg . It ran 12.7 every pass pretty quick car for stock and 75 shoot and lasted for over a year spraying the piss out of it lol.
