our latest project car. 2008 chally!

Man...what kind of HP numbers are you expecting? I would have guessed much more than 620 hp with 400 cfm heads....

I take it these are stock ported heads?

Woh....that is really cool, wish I had the cash to do that!
Please keep us posted!
Pics, Pics!!

I will have the flow sheets scanned before the end of the week.

This is a production 6.1 head with our own valve job, portwork and camshaft. The 2.08 valve outflowed a 2.100 Manley Valve by several CFM across the curve. It's a shame we are only running a .577 lift cam. If I could get a .650 lift solid roller into it, point more compression and an adjustable rocker this thing would make stooopid power.

last one made 620 on a mild 218/224 cam...
im only looking for 550 or so at the wheel on this one.
drivetrain eats up about 18 percent. so that would or should be around 650 or so.
cam is still mild...this is a computer friendly design.
223/227 .577 lift 114 lsa

heads move air. those numbers where on our bench. you know how that can change.
stock they where in the 330 range.

i also agree...needs a good turbo kit.

converter uses pairs of two bolts. total of 6.

converter used is a reworked stock case. case is an unuasual shape and ois about 9.5 inches in diameter...stock. internals are differant. about 2800 stall.

converter is alot deeper than a normal converter you might be used to seeing.

We got the goodies today. We'll work on them this week, and hopefully everything will be out our door Friday or Monday. What spark plugs, 5/8th or 13/16 ? Thanks.. Thanks for the trust. !!

Never mind on the plugs.. Thanks.. Man, UPS tried their hardest to destroy the head !! I took pics of the box. Still opening.

We really busted on it tonight...It's almost done now. It will be done minus bolt ons this weekend. After that, it's going to be fully tuned the next weekend. I can't wait...

Man, thats a neat and SMART project.

Its a lot cleaner, faster and I bet cheaper than trying to resurect a 40 year old rusted out chariot!!!

I think the new Challenger is growing on me. I really didnt like it at first and I think its a bit puffy and overweight and BIG. But IM starting to like it more and more, specially now thats available with a 6 speed.

Nice brave and great looking setup

its nice to work on.
almost simple.

the tuning is the hard part in my book.

thats the head that we have gotten to 390 peak cfm. off a stock 2.080 intake valve. the valve is a ferrera piece from mopar.

starting on the intake today.

Looks very nice

Cool project.

I was drooling over a black one with the 6-sp with ~800 miles on it yesterday. I was at the dealer getting some things done on my truck and there was one in the showroom. Apparently the owner got it for himself and it's already had a tranny. He's not sure if he's keeping it but it's parked in the showroom for now.

just thrashed through the weekend to get it all together and up and running.
today we will be taking some pics.
came out ok. the tuner was able to squeek some decent power out of the car.
its sister made 466 at the wheel. on a mustang dyno.
this one was even higher.

Can you list all the mods made to this car to get that kind of power...AND how much would all this cost for a DIY type build up. You talkin 475+HP at the rear wheels with no supercharger ?? That simply amazing !!

466 on a mustang dyno using a correction factor of 13 percent comes out to 526 at the wheel.
