Memory is going, I stand corrected, the 200 is bored larger the 170 is just stroked longer.

 

Nice 5 window truck. Mine are not that good of shape. I plan to retire in a year and that should free me up to get at my project vehicles.

 

Thank you, it's a labor of love as I'm sure everyone on here knows

 

170's were installed in 1960/72 Passenger Cars, 1961/70 Econolines and 1966/72 Bronco's.

The 144 is an anemic slug of an engine, barely has enough power to pull a sick trollop off a porcelain device.

144/170's have 4 main bearings, the 200 (first introduced in 1964 Fairlanes, used in Passenger Cars only thru 1983) has 7.

B&S: 144 = 3.50" x 2.50" / 170 = 3.50" x 2.94" / 200 = 3.68" x 3.13" / 250 = 3.68" x 3.91"

The 250 (also has 7 mains) was introduced in 1969, used in Passenger Cars only thru 1980.

If someone claims to have a rebuilt engine, ask to see the receipts for all the work done. No receipts = PASS!

66gpw: You sure that engine you got from the '70 Maverick is a 200? The 250 was also available.

The 200's bare block changed in 1968. The 250's bare block is different from a 200.

 

What's the latest year I can use a 200 for a direct bolt in. Thank you guys for all your help.

 

If I recall correctly, the early 170 had a different bolt pattern (bellhousing) than the later 170 / 200.

 

Yes it was a 200 that had been rebuilt. The fella owed me cash so I got the car from him. The motor had some miles on it, but less than 50,000 miles.
I had to drill another hole on the crossmember in my truck for it to mount in. The bell housing would not match. So I got an aluminum bell housing had it built up where I needed it to bolt on. But that was 13 years ago and never finished bolting it in, due to a family crisis. Now I like to go back to a 170 which I have in a parts van that was running at the time I bought it with the 4spd trans on it.
If it is not the 200 I was told at that time it was. How can a person visually tell the difference. I'm not up on engine building as much as I'm into the body work of vehicles.

 

If I am wrong someone correct me but a 170 has 4 frost plugs and a 200 has 5.

 

According to the parts catalog, 144/170 = 3 / 200/250 = 5 / C8AZ6026A .. 1 3/4" O.D. Core Plug.

 

Your right ND, I knew there was a difference but was too lazy to check.
I'm pretty sure there is adifference in the bolt pattern on the bellhousing, I think i've got a couple here, and a falcon 4 speed and shifter.
