The numbers you quote for the Hemi are at the crank. There's typically about 30-33% drivetrain loss observed on dynos, so that would come out to about 240 hp and 274 ft-lbs at the wheels. That will definitely not "walk around" my turbo jeep that's making about 425 hp and 415 ft-lbs at the wheels.
That's very... optimistic.
$1500 will probably get you a high mileage engine or one that needs some attention in one way or another before proceeding. Replacing a new low-mileage 3.6 V6 with an old high mileage small V8 that only makes about 26% more power seems pretty silly. Refurbished 5.7 Hemis are around $3000. But stilll... a lot of work for only 26% gain.
How can you sell your trans if you're reusing your trans And I doubt you'll sell a used 3.6 engine for $3k. Rubitrux sells used 3.6s for $2999 with free shipping. As a private seller, you'll have to undercut that to compete and you'll lose on the cost of shipping if you can't sell locally.
Conversion kits are more than $4k: [google shopping search link]
There's a lot more labor involved in a Hemi conversion compared to a bolt-on forced-induction kit. Forced induction kits are much more feasible as a weekend project for an amateur backyard mechanic. A v8 conversion requires another level of tools and skills that many people don't have.
