I'm thinking about starting a thread walking through performance mods to a basically stock 5.7 and working the build all the way through to a forced induction engine. We just purchased and altered 23T and rather than going straight to a built turbo engine we might try a 5.7 out of the junkyard and work it through some performance mods and document the gains or losses on our dyno. If you would like to see some test just let me know and if it fits the budget (and parts laying around the shop) we may give it a go. Most folks won't be running an altered but the HP/TQ info should be helpful. Thoughts?
I would love to see something just like that. Very interested.

Awesome Mike! Would love for someone to show just how easy these can make power. One thing I have wondered about is how much power is a Drag Pack intake worth over a ported 6.1 intake if any?

I've always been curious how much HP a stock 6.1 cam is worth in a 5.7 and how much the SRT exhaust manifolds are worth on a 5.7
6.1 cam swaps were the big fad with truck guys before the after market stepped in with other options. They were good for about 2 tenths and a couple mph in full size 14 sec Ram pickups. Plus the $85 price tag for a dealer direct billet roller was a no brainer.
AKA a "stage 1" cam lol....

Looking for a couple of 5.7 Hemi's to start my project with. If anyone knows where I can find a bare block, complete engine with a spun bearing or a runner please let me know. I had made arrangements to pick up a couple this Saturday but apparently someone beat me to them. I had to make a choice to drive to Tennessee to get the 23t or go get the 5.7's. I got the 23t. So now I need to start my search again.
Please email me if you know of any. Must be 2008 or older
We have one down at the shop we could probably part with, although its not mine, but they would probably part with it...Its actually a whole engine minus some parts.

Thought I would get this thread back to the top since I am seriously considering getting rid of my LA stuff and going 5.7 in my scamp. I have tried searching for the answer to this question high and low here, but haven't found much so thought I would ask
I am wondering about stock bottom ends and what they can handle. Looking at a 2008 core motor that currently has a spun rod bearing. I have heard that high ten's in a 3400lb car are easily achievable with these engines potential, and im wondering if that can be done with a stock bottom end (I know the pistons are cast, rods powdered, and the crank is cast- although cranks are said to be decent in strength) and with the early 5.7 heads? Or would something of this caliber require upgraded bottom end parts (i.e. 6.1 crank, rods?, pistons?) and something like 6.1 or 5.7 Eagle heads?
Any insight on this stuff would be great, and I have to say, I read this whole thread for about the third time and it has a TON of great info, so thanks to all who shared so far
Thanks!
No hands on experience hear, just what I read, just thinking of what may work for a low cost upgrade?
I like the used 6.1 crank and rods, custom pistons, 6.1 cam? A little head work and a stock 6.1 intake and upgraded exhuast, and it ought to run quite well. What do the experts think?

I see my thread got resurrected from the dead. I'm ready to pull the trigger. Looks like I'm going with a 5.7 block and 6.4 heads. Callies stuff on the bottom end and I'm guessin probably a custom Diamond piston. Rick Rondy was kind enough to share his header configuration since we are both using BondoBob's front end kit. Looks like TTI makes a 2" header that fits. Charlie's makes a nice pan that fits as well. Cam will obviously be critical. Mr Wheatcraft informed me that Coan makes the adapter to get my glide attached to the crank. Things I'm still up in the air on: Where to get a motorplate for the front? What water pump to run? Which intake to run? Drag Pak, Ritter, etc. Gonna be running my Ron's Terminator on top of it and it has a Dominator base. Here is my biggest quandry though. I refuse to give up the abilities of my current ignition system so I'm gonna have to run a distributor. Does anyone besides Jesel make a belt drive for the front of one of these? The Jesel one is pretty pricey ($2200 last I checked). Plus the Jesel deal has two distributors and I don't have a clue how you would fire both of them? The Mopar deal is kinda ugly with that thing sticking so far up out of the engine but may be the way I go and just plug the second plug holes off. For those of you who don't know me, this is going in a Challenger that currently weighs 2750 with me in the seat with a heavy R block. So this will most likely knock 75lbs off the front end and that is one of the main reasons I am looking at this deal besides the logevity and parts availability. Pretty sure this is gonna happen, I just gotta come up with my parts list now.

Don't get your hopes up on the weight break, Gen III are pretty freaking heavy.

Can you explain what you would be "giving up" ? 
Even the most basic controller like the MSD6013 offers two step launch timing, rpm parameter limiting, rev limiter, timing "smoother" for lopy cams, a simple plug and play harness, fully programmable RPM based timing curve, MAP sensor PSIa additional timing graph
..just can't figure what the dist would give you except something else to fail?

I've been working on a Belt Drive that still uses the factory cam sensor and phaser ring. I've been running one on my motor for the last 18 months and it's been flawless! I will be taking the motor apart soon to evaluate the parts, make any tweaks and then see if there's any interest to make them. The only thing, is you will need to run a belt driven oil pump, like a Petersen R4 Single Stage or similar, as the Belt Drive is exposed and a factory oil pump is withing the timing cover, driven off the crank.
Loose the distributor BS. It can't get any simpler with the Coil on Plug and an MSD 6013 Ignition Controller. And like mentioned else where, it is programmable!!
