67, 170 6 cyl.

[slotracer]

so I have this 67 Mustang that the engine tag said 170 on it, everyone says the 170 did not come in the 67 the 200 did, how do I tell the difference?

Block casting number, and/or count the freeze plugs.

3 freeze plugs right side engine, the #'s are 06DE under them are 6015A

170 was the base engine in the very early 65s (often called 64 1/2) when the first optional engine was the 260 2v.

It could be a replacement as could a 260 V8 as a replacement for a 289.

Three freeze plugs would indicate a 170 or a very early 200. The 200s should have five freeze plugs. Sound like you've had an engine swap by a P.O. The correct engine shouldn't be too hard to find. A 250 for that matter should be easily found.

Thanks for the Information, it is a fresh rebuild, if I run across a deal on a bigger 6 cly. I may switch but for now I will keep it.

If it's in good shape and runs well, why swap? As long as you're happy with it.
I've never driven a 170. Is there a great amount of difference between a 170 and a 200?

It boggles my mind why someone would put a fresh rebuilt 170 in a 67 Stang! To my knowledge the 170 has much smaller bore and therefore is a different engine. It was a carryover from the Falcon in early 64. PO must have gotten it dirt cheap to put in a 67...bigger car!

I had a 170 in my '70 Maverick and really liked it. Wasn't a big powerhouse but got great mileage.

Came across a 70 Maverick in 81 on the way to work on a little private used car lot. It was like a new car. It was from an Iowa farm. Only accessory was automatic...had radio blank out panel... had fiberglass belted bias tires. It was a very early 70 (spring 69 build) fit and finish was Lexus like! I'm not joking, it was incredible.

That little beauty had the 170 which was the original Maverick engine. That little I6 was bulletproof! Besides that it would do 0-60 eventually!!

Anyone want to see pic of that beauty PM me, I'll e-mail a couple pics...that was before digital cameras so I don't have a bunch!

(most) 170 and (most) 200s have substantially different blocks, with the 200s receiving the 7-main bottom end, hydraulic lifters, etc. There are early 200s with the lighter bottom end, and IIRC 170s were produced for marine, industrial, and export, and other uses long after 1965.
