Hey everyone,

New to this forum, but my Dad and I are replacing the engine in an '87 FTA with a Blueprint 383 engine.

Has anyone done this and can give us any pointers?

Specifically, about fit (it looks like the height may be an issue with existing motor mounts) and if you've successfully used the existing exhaust manifold with the new engine, understanding will decrease the new engine's HP slightly.

Thank you in advance!

The height will be an issue for sure.

Are you changing the front cradle at all?

Thank you,
PTA Staff
