That is a Magnuson MP112C blower. The carbs are Holley 94's that I had in my inventory. I am rebuilding the carbs and they'll be good as new. Other new carbs are expensive, and this is a budget project for me. I am locating the crank pulleys and belt tensioner...when I get them, I'll start the project. Still need to get a spark controller for my MSD6a to retard spark at full throttle and a new electric fan, as the old mechanical fan will be removed.
