Will 350 chevy engine fit in a wj?

If not what engines are direct bolt on for the 99 wj limited 4.7. Any help will be much appreciated, we just blew my engine and was curious to if there were any engine that are direct bolt on and a 350 would be pretty sweet.

Checks location.....yep.


Anyway, I'm sure it would fit, but unless you're doing an LSx series engine, why? Most older run readily available EFI SBC's make less power than the 4.7, not to mention you will need a standalone EFI and Transmission management system as well.

Yeah, an HO would be your best option for a drop in HP increase vs. the motor currently in your WJ. I would think at the very least you would need the underhood wiring harness since the HO's have two knock sensors (IIRC) and the PCM.

$695.49 more for HO.
This is one of those questions that "if you have to ask..."

A stroked sbc that is carbed would probably triple the numbers of a 4.7HO. I've seen big number hemi motors, so that's a different story.

Hemis won't fit without frame modification.

A H.O. Will require a new PCM and wiring harness. A Hemi requires major frame mods, and a lift, and hood modification. Any other v8 would require a nee transmission, as well as all new wiring, and none of the gauges would work.

Typing on phones sucks.
