225 slant 6 or 360 v8
Your post is quite helpful. I am new to this group. I have a 65 dart gt does the motor monuts work for this year as well? I am really trying to o the cheapest and easiest way to hp.
Those two words should never be in the same sentence, especialy in a 65; there is no easy, and there is no cheap.
The cheapest I have done it is by dropping in a complete running V8 with it's automatic and fenderwell headers. Even a 2bbl will make surprising performance through those headers, in a lightweight 65.
Additionally all you need for this is the front engine mounts. This is about the most basic swap there is.Even a tired junkyard teener will about nearly double your performance, over a tired 225.With 3.23s it should keep you happy for quite some time. Add a 4bbl and 3.55s, and you're all set.
I ran a 340 with teener 2bbl topend from the decks up,and the teener cam, in 65 long-roof with 2.76s. With skinny vintage 1969 tires,It was a blast! A real hoot! First gear was good to well over 60mph!
EDIT
OOps, 1969.............. almost same story;but make it a 360 to compensate for the slightly heavier bodystyle. And scratch the fenderwells, for any old header. If you intend to run the 7.25, make sure to put a Suregrip in it, or run some bigger rubber, cuz it may not last long being peg-legged with skinny tires.
