Anyone running an F1 on a stock 346? Want to know if you can tame a F1 back to around 8-10 lbs boost for a 346 yet have head unit for next engine that will most likely be a forged iron block 408. After pricing things out, looks a lot cheaper just to get the F1 up front.

I realize this is not the most optimum installation but will it work for a couple years?

 

With a 4.5" pulley you might be okay for a while. It is definitely the better route vs buying the D1SC then selling it and upgrading. I wish I had gone that way originally.

 

+1. Good plan.
