I am looking into building a daily drive, most likely a classic. Id like something with a little more room than a Stang, maybe its cousin the Falcon, little more room, lot of similar parts etc. I would install a 302 HO replacement crate. Its cheap ($3200 COMPLETE) its not a barn burner, only 225hp but thats plenty, T-5 trans, and good road gears. Im curious as to what fuel mileage this would get in a falcon/Mustang ( I would think it would be similar) Andone know or has anyone sun a setup like this? I just dont think the 200ci would have enough power for my tastes.

you do realize that with the technology available today, making 200hp from a 200ci six isnt much of a problem right?

yes I do, but FordSix wasnt thrilled with my trying to get that out of the 200, and i am conscerned about its fuel economy. I know the little 302 I have in my truck gets 20 and its only putting out 230hp and its pulling around a extended cab truck. I was hoping for about 24 in a small coupe.

turbo with ten pounds of boost, and megasquirt efi should get you right where you want to be.

I would rather have a stock 289 or 302 than a hot rodded I6. I had enough trouble with the 200 I6s holding up when they were stock. Now give me a 300 I6 and thats a different story.

A Falcon would be cool. With a 302 HO like your wanting to run and a T5 with 3.50 gears you should be able to get about 20 mpg highway and about 15 around town. Your RPMs will be around 2k on the highway at 70. If everything is running perfectly you may even get better than that. Are you going to run EFI or carb?

There is one thing I have decided for absolute, my 1968 Mustang will be pure classic miscle, 500 horses or old school muscle, almost stock interior except for front seats and instrument panel. Now as many miles as I cover this will never due to drive daily, fuel economy will be too poor, space too lacking.

That promted me to look at the Falcon, The Falcons were built alongside my stang in the same plant off the same lines, But they have more space and I have thought of building a pure street machine. The thought crossed my mind of using Fords new 5.0 crate engine. 412 horses and 26 mpg in the new stangs, maybe somewhat less mpg in a classic . It belts out plenty of power and economy, for a modest price (around $7,000). Classic but modern in performance and economy.

Id like this in a daily driver, but I dont want a modular engine in my stang, its an old school muscle icon and I intend to build that into the car.

My only conscern is what this will do to my budget, two expensive projects in the same decade, but I guess its all in my priorities.

dod you run the 200 without oil and coolant? you practically need a nuclear warhead to kill a ford small six, and even then if you replace the points and install a new battery they have a good chance of starting back up.

thats exactly what my impression on them were!!! ford made engines for IH and we had an I6 pickup that would seemingly run without oil and coolant! lol.
