Re: 350 Ram Jet Engine

Has anyone installed the Ram Jet 350 in a mid year Corvette. Purchased the engine, came with 14” externally balanced flywheel. Trying to use my Muncie 4 speed, but flywheel is too dig. Any help would de appreciated

You could use the 14" flywheel if you also use an 11" clutch and a bellhousing designed for use with a 14" flywheel (e.g. GM #3899621).

Otherwise, you can switch to an externally balanced 12-3/4" flywheel. The standard weight version is GM #14088650.

By the way, all Gen I small blocks equipped with a 1 piece seal type crankshaft such as your RamJet 350 use an externally balanced flywheel or flexplate.

A bit off topic, but does the plenum on a Ram Jet motor fit under a stock small block hood?

Yes it will. The midyear FI plenum is about 8" above the base plate and the Ramjet plenum is 8" as well.
