I found some old pictures of my turbo motor, and figured out how to post them. I built this in 1979.
Turbo 170 slant six

Not hood friendly! Cool stuff, Charlie!

Correct. The carb actually was up in the hood scoop.

Engine was in a 65 Valiant (fully street legal). Stock 170 engine with a mild Crane cam, stock 1bbl intake and exhaust manifolds. I did have the deck "O" ringed and copper head gasket but didn't need them. Head gasket problems were from detonation. Turbo was from a 1966 Corvair with a different compressor housing to get the 3 inch round rather than the Corvair small inlet with 3 bolts. Carb adapter was "homemade", and carb was a Holley 500 cfm 2bbl. Had 10-12 lbs boost, and ran 13.4's at about 104 in the 1/4 mile. I still have the car and engine, and hope to get it back together in about a year, with some up grades (boost timing master, wideband O2, and better water/alcohol injection system) that weren't available back when I built it.
PS: The carb adapter was water heated. At idle ice would form on the bottom of the adapter, and the engine would surge from fuel puddling, without the heat.

You should look at doing a 21st century revisit on a turbo build....

Can't really afford to do that. Too many other projects. Just going to use what I already have, with some "updates" for tuning I now have a boost timing master and a wide band O2 sensor. That should help me along with the EGT gauge I had on the system. The system actually worked pretty good, but was a bear to get it tuned to stay out of detonation. I know I left a lot on the table as far as power.
