6-71 small block build.

It begins!
I'm ready to order the blower kit and need some advice on what pulleys to get.

Congrats and good luck. IMO, start with the stock pulleys and see what you get. If your a tinkerer like me, order up two more smaller pulleys.

8mill belt or 1/2" tooth?
2 or 3" belt?

Bigger the better.....

I'd like a pulley combo that is close in tooth count so I can start out with less boost and when i get it figured out swap the pulleys for more boost? Is this even doable?

Yup

Heads will be open chamber cast iron for now. May go aluminum at a later time.
Pistons are undecided yet. I think I'm gonna look for a different LA 360 long block so I dont have to tear into my existing engine.
I will just start a new build and keep my 10.5-1 NA engine as a back up for now.

Anything you think I'm over looking, feel free to let me know.

Thanks guys!

Have fun!!!!
