Should the engine be centered?

How is the engine supposed to sit?

Should it be dead center between the shock towers?

Mine seems to be about a half inch more towards the passenger side.

289 block
stock heads
New original 65 engine mounts. (the rubber is new, but brackets are original.)

Variations in motor mounts can cause this. And you cannot assume that the engine compartment is symmetrical. Some were built out of kilter.

Probably not, I have an original '70 Mach I and a '65 fastback with the original mounts in both of them, and the engines both sit 3/8" to 1/2" to the passenger side of the car. On other Mustangs, I slot the engine mounts to move the engine over to the right to get clearance between the headers/exhaust, and the steering box. Your car will be fine as the engine does not have to be centered.

I'm not sure what Ford's spec was on the early Mustangs but it's not at all uncommon for automakers to offset the engine a bit, sometimes for clearance to certain components like steering shafts and etc, it also usually helps out vehicle balance in the most common condition (driver only.)

never paid attention to the mustangs even though i will look when i put the engine back but i noticed the one in the 66 wagon is more towards the passenger side and at a slight anlge>looking under the hood the front of engine is at about the 5 o'clock postion and the back of the engine at about 11 o'clock and the pinion is offset 1.75" more toward the passenger side.

I've been able to "adjust" the engine position a bit by loosening, NOT removing, the mounting bolts for the block mounts and the frame mounts as well as the intermediate bolt (or nut), prying the engine (It helps to use a cherry picker or hydrualic jack) into position and then re-tightening all the bolts. There is enough slop between them all to move the engine quite a ways actually.

I recall touring the Tickford/Prodrive/FPV facility in Australia a few years ago ('02?) when they were importing SN95 Cobras and converting them to RHD. They noted that the US LHD cars had the engine offset to the right - quite a bit, I want to say 40mm/1.5in - and that as part of the conversion they had to move the engine back to the center.

They did a LOT of work on those cars, and I don't think they sold more than a handful. Two-door cars were always a tough sell in Australia, a small niche market and not much more.

IIRC, the tax on 2-door cars is such that even in the early 60's, stock cars races were 4-door sedans.

Couple that with price of a Cobra, plus RHD conversion, and you've got a pretty small market. 2-door cars are not unknown there, though.
