FWIW I suspect that Shelby and crew knew that 58 mm was needed to extract most out of engine. I was into drag boats and had 48 mm webbers on one of my big block chevys, it always felt choked. Motor had good response from idle but suffered at top end. I know boats and cars are two different things but if anything boats will show weakness more in my opinion. That experience made the choice to use T.W.M. a easy one. They are 58mm. Have had the Kroyer motor for over 10 years on road with no problems and made close to 700 hp. I decided to freshen the original 427 side oiler in Bennett car because it had been sitting for over 10 years. Took it back up to Engines by Rex in Sacramento and they said why don't you put your extra T.W.M. injection setup on this engine and remove the sidewinder 1 four intake. Engine made around 500 hp. before and my comment was 500 is enough. Well the injection went on and a set of aluminum heads I had, now we have close to 700 hp. My long winded story is to confirm that along with the looks of webbers or 8 stack injection they will work great on street. Also picking up few extra hp. can't be bad can it?

1963 INDY "almost" engine
I don't know it this link will work, but here is an article with some very scant information on the original application for 58 DSF models....a small block Ford race only engine. The picture is one of several Ford published in the 1962 early 1963 time frame showing an aluminum push rod valvetrain engine being developed for the INDY 500.

Never heard of that "1968 Ford also offered a "Tunnel Port" HD 302 for Trans Am racing"
Very interesting !

The Tunnel Port 302s didn't work out well for various reasons. A few never give up types eventually got them to work and last at the same time.
There were all kinds of variations of small V8s 255 to 351 c.i.d. that Ford made for some racing application or another. That does not count the Gurney-Westlake 302s that were very strong, lots of power, very versatile, and long lasting.
The HP289s were the most widely used basic platform in the perhaps the widest variety of configurations; in some forms only a team like Shelby American could get. Example: You just won’t come across four bolt main cylinder blocks and forged steel crankshafts but they were in existence without many people knowing about them. There was even a brief flirt with Single Over Head Cam HP289s.
Not every idea or every development engine was successful enough or worth the effort to continue.

A friend had a pair of molded plastic ones he obtained from Ford long ago. They appeared to me to have been vacuum formed polycarbonate plastic to me.

I saw an interview recently of Dan Gurney where he stated that the cranks and rods were stock Ford items....I wondered about that.
My new book on the Ford Daytona coupe mentions a number of retirements of Cobras with broken cranks....leading me to ponder if there may have been some steel cranks back then.

This link has some errors. The HiPo 289 came out in spring 63. They don't mention the intake valve size increasing to 1.78" and what is up with the "The last year for the 302 4-barrel was 1970", without any mention the 69 and 70 were a Boss 302?
But has anyone ever heard of this? The 315hp 302 in 68? News to me.
"For 1968 only, a special high-performance version of the 302 was offered for the Shelby GT350. Its main features included a high-rise aluminum intake manifold, a larger Holley four-barrel carburetor, and bigger valves; 1.875" (intake) and 1.6" (exhaust). It had a longer-duration camshaft, still with hydraulic lifters. The block was a higher nickel content casting made in Mexico. "Hecho en Mexico" casting marks are present in the lifter valley, and its main strength was the appearance of much larger and stronger two-bolt main bearing caps on the engine's bottom end.
The heads had special close tolerance pushrod holes to guide the pushrods without rail rocker arms or stamped steel guide plates. The combustion chambers also featured a smaller quench design for a higher compression ratio and enhanced flow characteristics. Heavy-duty connecting rods with high strength bolts and a nodular iron crankshaft were also included in this package. It used high flow, cast iron exhaust manifolds similar to those on the 289 Hi-Po K-code engine. It was rated at 315 hp @ 6,000 rpm and 333 ft lbs of torque @ 3,800 rpm. This engine block is considered the strongest production 302 block other than the Boss 302 and the Trans Am 302. The package cost $692. It was not popular and did not return for 1969."
