Damn it! Wish I had the cabbage right now, how much are the valve covers needed?

Do 6.4 heads bolt on to 5.7 blocks? Or will the bore size shroud the valve? (hopefully I am saying that right)....

Also, do they use all the same rocker gear as say an early 5.7, so that it can all just transfer over to the 5.7 head?

Oh, and is there a difference between the 6.4 truck head and the SRT head? Are they both "Apache"?

It's too early to find out about the truck heads. I wish I knew.

I have a feeling the hellcat heads are identical also. They said they're made from a completely different alloy also.

09 and up 5.7 (eagle) use the same cover as the 6.4. The area that seals against the spark plug tube is recessed, because the plug tubes are shorter.

So can the 6.4 heads work on a 5.7 bore? Even with say a .020" overbore? If so, I am going to pull the trigger on those heads that sixpackgut mentioned...wondering if they are bare or complete heads for that price also.

Based on info from this read I would say no.. read it

I think Apaches need 4.06 or larger bores or a notch.

Charger; as for the electronics I have the MS3x box and the two harnesses, a pair of DIY Autotunes "Quadspark" coil driver boxes, boost control solenoid, air and coolant temp sensors. cam and crank sensors (OEM), coils (OEM),eight resistors for the low imp. injectors and a bunch of connectors from a junk yard harness. Almost all was purchased from www.diyautotune.com. The MS was bought in a kit form and the set up for the hemi is on their website.. There is a butt-load of wires in the harness, but I only used half....but half a "butt-load" is still a lot!
Eight injs., eight coils, TPS, temp sensors, fuel pump, power and ground. idle motor/solenoid (I don't use one)
It was a rewarding challenge.

And I don't like wires.lol
For budget reasons, I'll probably stick with a carb for a couple years, and if it's in the funds, swap over to injection at that time. I already have a CSU 750 E85 dual needle and seat carb so...

I believe holley has the hemi harness done for their holley efi

My ms3x kit comes in a simple pre wired harness. No mess at all and the coil drivers are built into the box.

Alex, I sent u a PM

It can be an expensive changeover, I know I'm in the middle of it, but the route you take depends on the core engine you end up with. I traded a 19yr old 400/448 for a worn out 6.1 that had dropped a valve. It needed bored .010 over and that turned into wth and stroking it. It came with new valves, one good head, a good 6.1 intake, New takeout pistons and rings, valvesprings, etc. The intake is why I chose the EFISource setup. If starting from scratch, going carb may save a few bucks but if efi is in the plans might as well get that ball rolling right off the bat.

I'm not even sure I'll ever go EFI. I'm not against carbs and there are all sorts of cars running way faster than I ever will using em. I guess I'm just trying to weigh my options at this point. I have a kick ass blow thru carb and an awesome pump/regulator. None of that would be any use so we will see. If I want the car on the streets next year, EFI will probably have to wait. I'm guessing I'll be digging for loose change since I'm starting from scratch and I'll also be buying a turbo or two.

Thats why I'm going with EFI now... I figure it'll
be at least a year before I get a gen 3 turbo built
up and in the mean time I can run the EFI on my 416
and learn about it and get the feel of it before I
hang the EFI on the gen 3 turbo

7.0 and 6.4 one is mine.......no build info

Someone needs to start a "What works and what does not Gen 3 Hemi" thread and sticky that sucker to the top.

Stuff like: what front dress, what oil pan, what hp level the stock crank/rods/pistons typically decide to die, whose engine mounts and headers work well, what heads fit what blocks, etc etc etc.
