Hello

A member here (Lunatic) has been kind enough to offer his help in making some proper engine and tranny mounts for me. I have a spare 88 cradle and F 23 tranny. My motor is a Series III motor, but I don't have a spare for a mockup. Series II are much easier to find, though I realize that the oil pan is different.

Question- If I grab a series II for a mockup (everything else is that same as what is in my car...88 cradle, F23 trans), will the engine mounts that work on a Series II mockup work on a Series III? Any interference problems between using engine mounts that work on a Series II to use them on a Series III later on?

thanks

Bump

Is there is a difference between series III and series II mounts?

Thanks

No

realistically, there is no such thing as a series3 if you discount the blower/throttle body.

The mounts are the same.......

Well there's a few small details that changed but overall that's true.

I do like the connecting rods on the L32 and the heads better, they're a little beefier and the heads are better flowing than the L67's.

Thanks everyone. I do understand that the differences are minor, but since I don't have 2 engines side by side, I wanted to be sure that the minor differences (i.e. oil pan) don't potentially cause issues when transferring mounts from a Series II to a Series III

I appreciate the help

Nothing suggests the rods are better. The heads are identical and the valves are less than a millimeter larger which does not mean they flow better it just means they are bigger.

Externally the series II and series III 3800 engines are the same. The difference is in the transmission (if you choose to go auto)The series III engine is bolted to a later design 4T65eHD transmission that would require a different RH (rear) swap mount.
