410 exhaust manifold

[Kevin H]

The rear exit manifold configuration was used by Bristol because the Bristol has a narrow engine bay compared to the Plodges that the engine came from.

As for the 313 and 318 engine, I thought there were identical other than the bore.

I recall reading an Automobile Quarterly article called "Maple Leaf Mutants", which explained that Chrysler had a bias to it's US market in favor of Canada. So the Chrysler cars offered by Canadian dealers were in effect last year's US model, or sometimes older.

I believe the 313 engine enabled Chrysler to offer what was essentially the same V8 engine in both markets, with the Canadian 313 being perceived as inferior to the American 318. There may have been some difference in carburation options also, such as the "Power Pack".
