Stroked340 is mentally challenged and also a uneducated, uninformed silly loser. If he dislikes "mexican" products he needs to go down to Mexico and inform Mexicans to stop sending products! Wanna be big shot! See what happens when u open ur big mouth down there!!

i"d still cote for the 408 easyer Hp down the road
This is a more simplistic /solid way to go. ( Actually what I would do,done it once already). Better street ability/ more potential all around performance, is available with the newer Hemi, it will take more time/ money/ and fabrication on your part. What are your goals, when this gig is done? Some soul searching, & some basic final parameters need to be set.

Yes, this is my M1 intake that I had bungs welded in for my EFI conversion to my 408. I did a bunch of port work on this intake and wanted to reuse it instead of buying the Edelbrock intake that already has the injector holes drilled. Hindsight, I should have just bought the new intake. Apparently the aluminum the M1 is made out of is ****. They had a hard time getting a good weld. I was expecting it to cost about $100-$150, but they hit me with $320. Needless to say I was pissed since the Edelbrock cost $370. So now I have a $500 M1 if you consider the cost to buy a new one. If anyone is thinking of doing this, suck it up and spend the $375 on the E-brock.
Thanks for all the input guys. After lots of research, it looks like the aftermarket has really started to support the 5.7 swap. If it were 2006 or so, when the support wasn't like it is now, I would have without a doubt stuck with the 408. I've also been completely honest with myself. I know I'm not going drag racing with this car anymore (been there- done that) so I don't need a 500+HP motor that will make you deaf and rattle your teeth out at the same time. Don't get me wrong, I'll take the HP, if it can be in a docile manner such as modern motors offer. I would like to see how bad I am at autocross along with packing the family in for a long ride on the weekend. The 5.7 offers things that would otherwise cost a small fortune for the 408, ie serpentine setup, already completely setup for EFI so I can reuse most of the harness, modern style A/C compressor, power steering pump, fair fuel mileage, etc. I will eventually get over it being so ugly and I will try and pretty it up a little. As far as all the hoopla about the name Hemi, I personally don't care about that and my car will not have a single Hemi call out or badge anywhere. More than likely, it will have factory style 340 badges. If you are still reading my rambling, I guess you tell what my decision is. BTW, it will have a cam an probably milled heads before it goes in the car...

I had an aftermarket serp belt setup on a 340. Next one will be JY Magnum. But even so- I can't help but think the aftermarket pan for the 5.7 will eat up just as much as swapping to serp belts on the 408. I think adapting/fabbing mounts for the A/C compressor to adapt a later one is probably the way to go on that update. Your M1 was probably not ever meant to have A/C (am I wrong?)- though it's possible for a touch more to the serp belt conversion you can also obtain a new style compressor swap.
Technically you can take the violence out of a small block's tone. No idea why you'd want to, but a much more conservative exhaust would do exactly what you want. Much of what it sounds like you're mentioning isn't really about the motor- it's more about the car. I think most of the difference really comes down to the chassis rather than the motor. An A body with a Hemi is still going to jump out like a 350hp A body, it's not going to be like an LX car. That's both good and bad- it's great if you want the car to hook up and go well, not so great if you want a softer application of power. I went to EFI on my car with the SB and I don't think I'll be headed back anytime soon, not sure why I've not been robbing harnesses with all the gear yet- such a great improvement without much work and the cost wasn't outrageous. (my complete setup to convert to EFI using the OBD-II has like right around $500 with everything from the computer to the fuel pump and lines) Just turn the keyswitch and it fires up like nothing and tunes itself for changing conditions.
