Engine ID
I've been in the market for a 73-79 4x4 and am going to look at a couple this weekend.
Question is how can I tell what engine it has. The one i'm most interested in is a '75 f100 4x4 with a 4spd and 390. Is there an easy way to tell if in fact it actually is a 390?

UTfball68 has it all down.
two ways that the 390 could have been in that truck. if the engine was swapped in. or if the truck was converted to 4wd.
a 351W and C didn't come in 73-79 trucks.
when being sold a 360 always magically becomes a 390. so does a 351M to a 400. and so on.
I hope you buy this truck. good luck! keep us posted.

Bring a dowel, pencil, tape measure, 13/16-15/16 sockets, four inch extension and ratchet to remove the plug, and turn the crank. Make a mark at the bottom of the pistons travel, and make a mark at the top. Measure the two lines, 3.5" is a 360, 3.75" is a 390. If it comes out different, measure it again. If it comes out different from that, re-measure it. If it comes out past the 390 mark, and has a counterweight on the harmonic balancer, do not say anything cept "yep, its a 390"(or whatever the seller says it has) pay the seller the asking price, and haul a$$ home.
