Tech Question
Tom Schaffhausen, St. Paul, MN, 1965 Plymouth Belvedere II hardtop 318
I want to do a motor change. I have a 1962 413 engine I want to put in my '65 Belvedere. I bought a '65 Newport that had the original 383 engine and auto transmission. Will the 65 auto tranny bolt up to my 413 engine and then fit in my '65 belvedere?
Tom-
Yes, it will all fit, all you'll really need is an engine mount setup from Schumacher. As you probably know, 1965 727 transmissions are highly prized - they were one-year-only: cable-shifted, yet sliding-spline output.
While this is a pretty nice swap, there a a few things about it that I find less than appealing, mostly relating to the engine weight vs. power deal. You can build a 408" smallblock cheaply that will easily make as much power as a near-stock (non-Maxi) 413, be an easier installation, and even keep the stock trans. Or, a 400" '72-up B-engine is nearly the same displacement, is smaller, lighter, has better heads (again, assuming a non-Maxi 413), stiffer cylinder walls, etc.
Assuming that you insist on an RB engine, why not at least start with a 440? It weighs no more than the 413, and all '67-up 440 blocks are stronger than your 413, most also have much better heads, too.
So, to be clear, my point is: if you're going to go to the trouble of a swap, the cost of the "core" engine is one of the lesser expenses. Yes, the 413 is certainly not a bad engine, but why not make the best possible choice?
