Default 4 cylinder Thompson blower setup

This is on FB Marketplace now. Tony is a great guy, always has good stuff for sale. Thought someone might be interested in it. Not easy to come by! (blower not included)

Works for me. You probably need to be in the M/T equipment group that I’m in.
Here’s the post.

For sale: RARE THOMPSON Pontiac 4 cylinder 4-71 blower set up. Blower isn’t included, empty case just for display. What’s included is the 4-71 manifold, idler bracket, rear bearing cover for blower, 2 magnesium valley pan breathers, homemade adapter and 3 Scott injectors for the top of the blower , homemade manifold to run the homemade Scott injectors instead of the blower and a aluminum Pontiac timing cover. Manifold has had a few thread repairs and a divider installed. The idler bracket is missing the idler pulley. The rear bearing cover has provisions for 2 drives, fuel or water. The rare mag valley pan breathers are in great shape. The timing cover isn’t a Thompson unit but could be used to complete this setup. Some light modifications will need to be made to be able to run the idler bracket on this timing cover. If I was a betting man, I’d say this set up was ran at Bonneville. Ran in blown and blown classes. 3500$ plus the ride

Thanks for the reply and I will join the group. Fairly priced from what I have seen.
