VIN/motor question

The true location for the VIN is stamped on the inner fender, Drivers side. The fender mounting flange has a notch in it. You should see the VIN in the notched area. It should match the number on the door plate. But things happen, doors get replaced, errors occured on the line etc.

I don't know how to tell the difference btwn a 200 and a 240. In 38 years anything could have been swapped in there. But no 66 mustang left the factory with a 240 Does your car have 4 lug nuts or 5 on each wheel?

The 240ci I6 and it's brother 300ci I6 were designed as a truck motors. They are huge; very tall and long. Getting one to fit in a '66 would be tough. There was only one I6 available in '66 - the 200ci. The 170ci I6 was dropped after the 64/65 models.

It's not possible to fit a 240 I6 in a classic mustang without MAJOR modification to the firewall and radiator placement. So much so that it's really not worth doing unless you're building a dragstrip only motor. IIRC the 240 is taller and would require at least a scoop if not the whole centerline of the hood to be *moved*. You don't have a 240 and I would suggest a different mechanic if he can't tell the difference.

You are correct. Unlike the other 2 major American car companies, Ford had

2 different style inline 6 cylinder blocks. The 177, 200 and 250 cid were small blocks placed in cars, while the 240 and 300 cid were large blocks placed in trucks. The large bocks are heavy and huge - you may be able to place one in a full sized car like a Galaxy (fer Gawd's sakes why would somebody want to do that?), but not a Mustang.

You are correct - this person needs to find another mechanic pronto!

The Chevy 292 I-6 was the equivalent of the 240/300 Ford... a big, stout stump puller.
