The 5.7 car intake has the most torque (08- and prior). The 6.1 intake gives up ~ 5 ftlb to the 5.7 intake down low, but passes it around 5200 and has good power through 6400 or so. The drag pack intake loves RPM and is the best of the carb style intakes, with better high end hp than the two efi intakes. I've heard significantly more than the 6.1 above 7000 on up to 8200. It does however give up significant torque down low to the 6.1 and 5.7.
The LX guys typically do not rev past 6400 with their tuned stock computers, so I'm anxious to see what my ported 6.1 intake will do above 6400.

A great budget option is a 5.7 eagle intake, if you've got a 5.7 early head with big enough ports (or the intake spacers) or a 6.1 head.
An old style 5.7 intake will not be a limiting factor on most of the hemi swaps in an old car. I've had it go 11.50 @ 117 with a 5.7 392 swap back in 08 @4150 raceweight.
It won't look pretty, but it will work.

09 GC here 5.7...... Stock exhaust is very restrictive..... I put a full srt8 exhaust on and huge difference...... Stock shorty srt8 headers work great....... With a CAI and 93 diablo tune my porky jeep ran 14.18. Not bad for 4400lbs...... Also runs up to 140mph with ease....... Stock eagle heads flow more than 300cfm..... My stock BB edelbrock heads flow 290..... These small block hemis are the shizzle! I plan a 392 rotating assembly and fully ported eagle heads and maybe run the stock 6.4 hemi VVT cam (580/530) lift and right at 11-1 CR should get me around 450 rwhp....... TBF

Hey guys,
I know there are various threads on here that cover new hemi builds of various varieties, parts interchangeability, etc. However, I like many others have thought about performing the swap into their cars, yet find it hard to lay out a list of I will need and how much everything would roughly cost. I think that is part of why so many guys stay away from the swap, since they are not sure what is involved.
Anyways, I was thinking that maybe this thread could be a place where people who have retrofitted these engines into the older body styles can post up their builds (i.e. what parts were used in their actual engine build, rough cost if comfortable sharing) as well as what parts were NEEDED to get the engine to work in your car (i.e. special headers, mounts, etc. and what the cost was). I know it might be a lot of info to share, and some may not be willing, but I think it could be a great way to share the potential these motors have and just what is needed to get them running in an older car
If anyone would care to share, im sure I and many others would greatly appreciate it

Not really a performance build up except comparing to the stock six banger, but a hemi swap anyway. At first ti seemed like there is no way itr would fit, but in the end the 5.7 out of a 2004 Durango and a 904 trans slipped in there just fine. Had to modify the engine mounts, oil pan/pick up and build new "exhaust manifolds". Solved the fuel iSSue by installing a half gallon auxilar tank in to the engine bay where the original in tank carburator pumps supply the fuel. After that is a MSD EFI pump + rgulator, and the return is to the auxilar tank. Seems to work fine. The wiring and computer came from Bouchillon performance as well as the 2003 "fly by wire gas pedal signal conversion box". Didn't expect much of the combo, but I must say that there truely has happened some progress in the 40 or so years, when the last predecessor was designed! Oh, and almost forgot; the power steering pump puked all the gaskets out of the stock rack & pinion, replaced it with a GM LT1 pump that has lower pressure. Needed new oil lines, drilling the mounting holes bigger and honing the stock pulleys hole bigger to fit the GM pump. http://kuvablogi.com/blog/24173/7/

I am trying to find out what are good core engines to buy, what to avoid etc. I make billet parts and would like to start branching out into the late Hemi stuff, so I will be needing an engine to start with. I am looking at bringing over an engine or two come middle of the year. The one thing I am noticing is that one thing that might be worthwhile me looking at is timing covers.
Incidently, The companies I use to Sea freight to Australia are based in LA and Indianapolis, so If I could source an engine when the time comes close to those area it would be great.

I've got a bit of a stupid question....has anybody used a motor plate on new Hemi yet? It seems like it would be easier to mount that way. I'm no expert, I just read a lot of things when I get bored.
Here's Mine....

Hey steff, whats your motor build going to be this time around?
You basically proved to me that I don't want to use stock rods
