What will fit

[Nospark]

I have '66 Stang with factory 200. What is largest straight 6 that will fit without modification? 250?.

200. 250/300 will require some modifications.

OK, I'm going to revisit the 200 in the car and determine why I'm getting coolant in the combustion chamber. I'm never licky when it comes to these things so doubt the head gasket is sole cause.

The 250ci fits, but there is less than 1" of clearance between the top of the air cleaner and the inside of the hood. I need some Maverick mounts but I don't know where to find them. Does anybody know if adjustable 302ci mounts would work? I like the idea of having a 300ci in my Mustang but that requires a mechanical fan delete, special motor mounts, and a cowl hood.
