I helped my buddy pick this up recently. 69 Z/28 purchased by previous owner in the early 1970s. Parked since 1984 in a backyard. The owner, Larry Schreib, published magazine articles and wrote how to books including Smokey Yunick's Power Secrets. My friend and I have been visiting the car and owner for 5+ years and my buddy finally was able to purchase and we hauled it home yesterday. It's got a hi-po built 302 by Gale Banks Engineering's engine guy, Hank The Crank did the crank and special rods and pistons. This special sbc tripower intake setup is one of 3 or 4 developed by Smokey Yunick. The previous owner bought the intake from Smokey in the early 1980's while putting together his book. The car also has a Doug Nash 5 speed, full Recaro interior, and driver's side had these cool Christen Aerobatic aircraft seat belts. Larry also has a set of 15x8 Corvette rally wheels he ran on the car with offset changed to fit car (4.5" BS rear, 5.5" BS front). Cool car.

Those look like reset 15x8s, very common in the so cal Gulstrand Traco built circle of road racy street cars, Taylor made wheels in south gate ca reset most of them.

Interestingly, while chatting again with the previous owner, Larry Schreib, he mentioned he had the car at Gulstrand's shop for some of the work on the car.

Angle plug heads too, possibly 340292 turbo heads?

Several, several years ago, One of the major magazines, maybe Hot Rod had a page in the back of each issue called "Quick, What's wrong with this picture?" If you were the first to mail in your answer, I think you got a 1 year subscription. Anyway, in one issue there was a small block Chevy with an intake similar to this one. I don't remember much about it but I think I remember the article saying the carbs had the same spacing as a big block intake so that the factory air cleaner assembly could be used. That was in the 70's or very early 80's so I could be way off.

Smokey took 3 Camaros to Bonneville in October 1967 and broke a lot of records using different SB and BB combos.

I wounder if he ran the 3x2BB set up there as well as single 4BB and 2x4BB to set some records ?

are there date codes on the Holleys?
