Boys,
Not necessarily a T/A engine, however, what is it? Winner gets a cookie.
Click on pic to enlarge.
I would guess some kind of Indy 500 motor
Donovan aluminum Chevy small block 350 with 'custom machined' hemi-spherical heads and (mechanical fuel injection- Hilborn or similar).. :)

Well I see it says Donovan on the block, I thought since it is not a T/A engine the question was oriented toward what application.
A friend of mine and 'famous - or infamous?' - depending upon whom one spoke to... :) .. 62 Corvette expert (Dale Pearman -now deceased) had a 400 ci Donovan engine in a '62 Corvette 'street car' once upon a time - it was really wicked!... not sure where that Corvette went to...?

You get half a cookie. Who made the cylinder heads?
Smokey Yunick?
Mickey Thompson?
We know what Smokey once did some 'small block hemi head' work for Chevrolet, but I don't recall ever seeing those heads; from examining the machine marks on the heads, doubt anyone could *tell* who machined them out.. :)
I can do a paste and search on Donovan.
So what is the application?
Hemisperical heads for small block Fords...
Scott
Hammerhead
Did it actually ever run?
Boys,
Here is a clue for the heads: So-Cal.
Leo Lyons heads?
I think he was from Riverside, CA.

Jon,
You are correct, and the Winnah! You get a cookie.
Thanks. If the cookie has chocolate chips, I'll take two.
