Here is the replica Grand Sport engine in my '63 Grand Sport vintage racer.
You are looking at an all-aluminum SBC based on an early Donovan aluminum block, AFR heads, and a Moon intake manifold fed by Italian Weber DCOE45 carburators.
This is the engine in my FI '60 in one of the rare times it has one of my FI units on it. Usually it's wearing a customer FI unit. This is my mongrel FI, the involuntary victim of my unending experimenting in search of ways to make FI better.
No matter what you think of Chrysler--in the 60s the Factory was "all in". You didn't see this kind of stuff originating from the GM tower
I always tell people that think the GTO was the first muscle car by the definition of a full size car engine in an intermediate bodied car is WRONG by several yeas as Chrysler had very high compression cross ram dual quad 413s back in 1962 that would blow the doors off ANY factory built production car.
Nice car you have there Dan. Was it raced by a well know person when new?
I like the Chrysler Ram Induction but have learned to appreciate the Rat motor. Interesting discussion about Chrysler vs GM when it came to being all in as Mr. Hampton put it. My theory is that Chrysler's Hemi development was a WW II aviation engine effort supplanted by Jet technology. When Chrysler developed it into the Hemi for passenger car engines it had higher volumetric efficiency than Olds or Caddy. Racers paid attention, Briggs Cunningham and the like went to Chrysler Chief engineer Bob Rogers, a racer at heart himself and said why don't you guys build a car for that engine? At the time Exner was finishing up the all new 55 Chryslers. Rogers lobbied for a special version with a stiff suspension and dual quads on a race cammed version of the 331. It would be the very first factory built race car that could be used on the street. It made 300 HP, the first street car to do so and the 300 was born. Those who raced them, Cunningham and Carl Kiekhaefer in particular worked closely with Chrysler to improve the Hemi. The Hemi begot the b/RB wedge upon which the 426 Hemi was based. So for Chrysler, its V8's were always born of high performance, so they were as Dan put it "all in" for going fast. Bob Rogers was the spirit behind almost all of this.
Chevrolet's small block V8 on the other hand was built entirely to a cost and function under the hood of an inexpensive car. It was small and light. It used stamped steel rockers on pressed studs instead of shafts. Ed Cole designed a good little engine whose ubiquity rather than technical brilliance was its success. To make it race reliably it needs modifications. The Chrysler engines would use more fuel and air to do the same thing. Chrysler engines and transmissions were the best in the world for a long time. Some might argue they still are. Not for long.
