I have what was told is an original 67 F100. My problem is determining the engine size. My father gave it to me; and he thinks it has a 390 in it. If it is orginal according to the information I have found it has a 352. The engine code is Y in the VIN. I cannot find the data tag that should been under the coil. Is there anything special I can look for to determine what the engine is? The Net Horsepower on the data plate is 170.

 

My 1970 truck has a "Y" also and is a 360.
According to the "The Ford V8 Engine workshop"
'66 to '67 "Y"'s are a 352 and are rated at 208hp

WA, 170hp is listed for a 62 Y-block 292 and that has a exhaust crossover in front of the engine.

A 67 F100 would have a 352, with 208 hp
the 352 & 390 are both FE engines and as far as I know, there is no visual way to tell them apart, without internal measurements.

Good luck

If the engine is original then it is a 352. I am not aware of any factory installed 390 in an F-series pick-up. Unless you purchased the vehicle new or know its entire history then a lot can change in 32 years. This includes overboring of the original engine or engine replacement. A 352 has a 4.00" bore while the 360, 390 & 410 have a 4.05" bore. There isn't anyway to determine bore without head removal. There is a way to tell between a 352/360 and a 390 or 410 however, using a guess-timation technique with a small wooden dowel to measure the length of the stroke. The 352 and 360 share the same crank and their stroke length is 3.50". The 390's stroke is 3.78" and the 410's is 3.98". Rotate the engine until you have the No. 1 cylinder at Top-Dead-Center (TDC). Remove the No. 1 plug and insert the dowel until it hits the piston. Mark the dowel location using the valve cover lip as a reference. Turn the vehicle over until the piston is at its bottom-most location in the travel. Mark the dowel again using the same valve-cover lip point of reference. Simply measure between the two marks. You should now have an idea of the stroke length. I hope this helps you figure out which engine you have.
