I'm soon to start building my 60 Ranch Wagon two door. Plans are to build a street rod out of it, so I'm entertaining motor ideas. I have access to a 351W roller thats in need of rebuild. I also have aluminum Edelbrock heads. I'd like to have a manual transmission, and fuel injection. My engine options so far:

1. Build a stroker out of the 351 and add a Tremec T56 Magnum (Tremec kit is probably 7k)
2. Source a pull out 7.3 Godzilla. These seem to be going for around 8k with an automatic transmission. I'm unsure as to how much I'd spend if pulleys, oil pan, etc would have to be changed, and I'm really dont care to run the auto trans.
3. Source a pull out 5.0 Coyote motor and manual transmission. Seems they can be had for around 8-10K. Again I'm unsure about how much I'd need to spend to fit it
but this seems to be a viable option with being able to use the transmission also.

Thoughts, ideas?
