Build my own srt8
Hey guys,

I am thinking of starting with a 05 fully loaded limited then building a 6.4l stroker with an srt bumper and the roll bars from an srt. Total for this is 3690. Other option is pay 6000 more and get an srt 6.1 then adding elsds for 9000 more. I don't want to Lower my 5.7. I can always add srt wheels and tires for 200 more I got a guy willing to trade for my wheels and tires. The way I see it is more Hp, less money, dual speed transfer case, and higher resale for custom car. I know it's messy but I get the pride of building it myself. I have figured out the prices already. Win win win what do you guys think?

Im not sure how well the 5.7 transfercase and trans will hold up to the power. I know even the SRT trans is rated at 500hp i believe, and with a 6.4 stroker you should be beyond that so you will need maybe a SHR NAG1 trans.

I have heard the transfer cases are really strong so I am hoping that's not a problem. According to chryslers naming scheme the 5-45rfe should handle 500 ft lbs of torque so if the brand new 6.4l srt is putting out 465 lbs with a stock 5.7 upper end i should be around 450. Correct me if I am wrong please.

What all do you plan to do motor work wise to the 5.7?

Re: Build my own srt8
You could go with something like a 224/224 cam and put more power out. But it won't be as daily driver friendly.

Re: Build my own srt8
Yeah a 224/224 would be a more aggressive cam, but this will be my daily driver. With the 224 I will lose a lot of my low end torque and I do plan to take off the bumper sometimes and go off road, so I would like to keep some of the power down low, since I do have quadra drive 2. The 224 will also generate more power which I'm not sure my trans will like. I'm hoping I can really achieve something that has a lot of power and I can take off road with just a few modifications. Do you think this is a pretty good option versus buying an srt8? Or is there something I'm not seeing?

Re: Build my own srt8
I dont know if you will see power numbers like an srt but you should have a good sloid motor. But you still might want to have your trans double checked, make sure nothing is wrong or worn. The last thing you want is to finish the motor and take if for a ride and smoke the trans. With numbers around 350 you should be fine.

Re: Build my own srt8
Around 350 Hp? The stock 5.7l makes 335 so with the stroker I should be around 450, but I think I will definitely be above a stock wk 1 srt8, right? Also, is the intake manifold between the 5.7 and the 6.4 from the factory the same or atleast very similar? They look the same.

Re: Build my own srt8
I was meaning 350 to the wheels, it all depends on your combination of pistons, crank, heads, cams, and everything else. I'm not sure about the intake's being the same. What do you plan on doing to the heads?
