but i wanna find out how many cubic inches the 4.2l v8 is.

That's a 255 CID V-8, and they're awful. My father had one brand new back in 1980. Only used from 1980 - 1982, before they canned it. Less power, and the same fuel mileage, as a 302.

so he should prolly just drop a 302 in it and be done with it huh?

If it was mine and a driver that's what I'd do. If for no other reason than 302 parts are cheaper and more available.

Then again if the car is cherry or could be restored to like new, then it might be worth keeping it original just for the rarity of the motor. I lean more toward preserving on most any car that's in good shape and a little different no matter the worth of it now.... never know about later.

well the body was all rusted and we started to fix it but we think we might just drop in the 5.0 and be done with it.

well the body was all rusted ....

In that case.... I'd be looking for a 302.

Put a 302 with a 4bbl in and call it a day

just go to google and say how many cubic inches to 4.2L here, ill do it for you, it gives oyu a ballpark, its not exact, for instance the 5.0 is exactly 305 cu in but ford makes it at 302, yours is approximately 256 cu in

Inline 6 in a Fox Bird??? I have never knew that! I know those style Birds didn't last long but I think they look good! Potential to look good anyway. someone should do up the inline 6 in one!

BTW there are 61 Cubic inches in a liter so you should be able to figure out any Liter to Cubic inch or the other way around knowing that

Inline 6 in a Fox Bird??? ...

Don't know for sure if the 'Birds ever came with an I6 but the Fox Fairmonts and Zephyrs of the same era had the small 3.3L I6. Probably wouldn't be too big a reach to fit a 4.9L I6 under the hood too if my memory serves... haven't seen a T'Bird of that vintage in person since they were near new. The I6 would be cheaper to get initially but the go fast options aren't as varied for the 6 as the V8 of course.

Yes, the 255s were crap. I had a new 80 Town Landau with the 302, 3 sp auto until a illegal T-boned me in 83. Got an 81 with 302 and the 4 sp auto as a replacement. Nice cars and ahead of their time. Recaro seats were an option as well as the TRX (390 mm) wheels/tires. Never heard of the inline 6 in them.
