I have a 1966 Mustang 2 door coupe with a factory straight 6 200 and C4 "cruise 'o matic" 3 speed automatic trans. Thinking about changing up the engine, including swaps, boring, etc. Anyone got recommendations? Sorry...this one isn't getting a BBF or maybe not even a V8. 4 lug wheels and soft shocks would have to be replaced. Feel free to suggest any ideas. Just want to get some more performance while retaining a stockish appearance (such as putting in a 250 straight 6 etc). Just wanted to see if there were other options i hadn't considered and any advice. I realize i could beef up the 200 with a cam and whatnot. Looking for alternatives to that.
Thanks a ton,

The I6 is what it is and IMHO cannot become a horsepower monster economically. Changing to a V8 requires a substantial change in suspension in addition to the engine, itself. The 351W option mentioned, while doable, is not a good choice for your engine bay, but any 289-302-5.0 or derivitive thereof is ideal, but the suspension changes are really mandatory for safety and reliability.
Not wanting gobs of horsepower, but thanks for the advice. My car has a 3.20 rear so not bad i guess. What are everyone's thoughts about swapping straight 6's to a 250 or 300? Provided they fit which apparently they can.

Simplest is to drop in a post '86 carburetored 302 from a Ford truck. If you want fuel injections, get an after market system which doesn't require all the sensor connections. Front suspension can be redone for as low as $400 for new parts and get the disc front brakes from a 68. Any money leftover put in a 4 speed. You can go from there with cams in intakes and all sorts of goodies.
Thanks man. Thinking of doing that. Something like a 2 barrel carb/intake, 250 head, better exhaust header, etc. Curious if anyone has found an easy fix to some potential throttle linkage issues with the aftermarket header?
