So...I've read most of these 10 pages and I feel I'm suffering from information overload, LOL. I am obviously a Gen III newbe...my question, simply stated would be if I was going to a salvage yard looking for base parts to build a street strip Gen III what would be the desired parts to put on my shopping list, IE, desired years, configuration, short blocks, intakes, heads, etc.? Hope this isn't oversimplifying my question, thanks in advance.

hard to beat an eagle 5.7 from a truck, its got the best intake, almost the best heads, decent compression, the pistons are stronger than the earlier one, rods are slightly better, if you don't like VVT (I like it) then it is easy to lock out, if you like MDS (I like it) get one from a 1500 if you dont get one from a 2500 3500 or just leave the solenoids in and don't worry about it. The 6.4 apache cam is a real nice, easy upgrade. Short of coughing up the big bucks for a 6.4 apache or 6.4 BGE and upgradeing the cam with the apache, this is about the easiest cheapest route to big power.

Good info, thanks, any particular year to stay away from or are any years more desirable than others?

1st, I know this is an old thread but I just re-read all 10 pages and didn't see my questions asked or answered. 03 ram 5.7 with 4 cooked rod bearings, suspect a failed oil change to be at fault. I have an extremely low mileage 06 jeep long block to swap in the truck after an .030 overbore ( due to water sitting in the bores and pitting the cyl walls). I'm wanting to know if the 06 MDS cam will work fine in my 03 non MDS build. I already plugged the MDS with billit plugs and the truck was NON-MDS to begin with. I guess my question is, is the cam the same ? The 03 cam looks like it got hot with the rest of the 03 engine. I'm using all the accessories from the truck, just basically replacing the engine with the rebuilt 06 long block minus the MDS.
2nd. Should I swap to the 6.1 valve springs and pushrods while the engine is apart. Short block is assembled, putting the rest together today if possible.
PS. The intended use of this will be a daily driven 2500 4x4 with 4.10 gears, and pulling a boat or camper or race car around.
Thanks in advance.

#1 The cam is not the same, but it's fine to use. #2 while it's apart might as well upgrade to the 6.1 stuff.
Truth has no agenda, but those with an agenda make their own truth. Some of us are so open minded they only see their View

What are your thoughts about using an 06 6.1 cam while I'm at it ? My dealership can get me the cam and springs overnight for around 550 bucks, haven't checked on the pushrods yet. And if I do the cam, will it need a tune ? Just looking for torque, pulling, mileage.

I was quoted $68 for a 6.4 cam and $300 for a 5.7 cam. Didn't price the springs. A full set of lifters for my 2012 Ram was a little over $500.

I'm sorely tempted to do one before I retire, and likely retire the car. I'd freshen the 360 and sell it to free up some cash. My "vision" is a standard bore 5.7 with H-beam rods and a forged piston shooting for 10.5-11.0:1 compression. Basically stock heads, and a bigger cam that will still play nice with the stock rockers. I'd go the carb route, with something like an 850-950 Holley. I would obviously like to stick with my 904, and the 5.13's I'm currently running. I currently run a motor plate and electric water pump. I see headers and ignition as big hurdles in a 69 Dart with a stock cross member. What else? As it stands, I don't see this being a tremendous deal, or am I dreaming in technicolor?

It's not that big of a deal, Headers Call TTI they make em, Ignition , MSD Hemi-6 is the box you want. aeicnc.com is a good place for motor plate, Stock bore and stroke 5.7 10-12 to 1 compression , Comp cams 273 Arrow/prefix single plane intake will get you about 500Hp with some work to the 03-08 heads , If you go with the 09+ 5.7 eagle heads 500Hp is easier. Manley has a good stock bore piston so does DSS, 6.1 cranks are getting harder to find just keep that in mind. Eagle and Scat both have decent H- beam rods for under 500 There is user here that sells the Prefix line of products, search around the G3 section and you'll find hemi

Milodon pan, TTI Mounts, TTI headers, factory suspension and steering box - car is a 67 Belvedere II.
Very smooth install however full lock causes the drag link to interfere and scrape the back of the pan well.
This could result in the pan cracking after time.
Simple solution is to split a couple of feet of 3/4 ID hose and wrap the drag link with it.
More professional fix is to weld a couple of 3/16 turn stops on the lower control arms.

Maybe you could slot the motor mount holes a smidge

All, I don't know if this information has been provided quite yet but I wanted to let everyone know. I just got a camshaft quoted from Comp Cams and LSM. For a solid roller VVT from LSM, it would be $1200. Comp cams doesn't have any VVT cores but for a solid roller non VVT cam the cost was about $1100. Both of these cams were going to be high rpm big duration camshafts for my engine build. Just an fyi for anyone interested.
