Which hemi? 6.1 for $4000 or build forged 5.7?

If it were me, I would buy the complete 6.1L and get the car running! The 6.1L is no slouch and should be good for an easy 500+HP with some bolt ons and tuning.

Then build the 5.7L as a spare engine, or slam it together and sell it to recoup some money. Or... Build it for 800HP at your leisure, drop that in and sell the 6.1L at a later date. Either way, don't pass up the 6.1L.
