And how many ponies do the stock 5.7 and 6.1 Hemi's make? factory specs are 390 hp/407 ft lbs for the second gen 5.7, and 425 hp/420 ft lbs for the new 6.1. I realize those engines have more potential than that, but at what cost? Even getting a 5.7 will cost a pretty penny (The "cheap" ones I've seen on craigslist are between $1,000 and $1,500, and thats used). And once you've got it you still have to put it in, after you spend $1,200 just on headers to make it fit,plus mounts, new radiator and fans to keep it from overheating, etc. I bought my 340 short block for $280, had it rebuilt with high comp pistons for $1,200, and will have cleaned up eddy heads for under $2k. All said and done I should have a 400 hp 340 (which won't weigh any more than a new 5.7 with the alum heads, intake etc...) for under $5k. I would really like to see a 5.7 rebuilt and ready to go for less than that...XV sells their 5.7 carb motor for $6,700, and you'd still have to do the swap.
