Whats the biggest street cam I can use?

[USCG CHARGER]

I'm building a 416 from and R1 59* block with heavily ported W9 heads ported by Phil Colman I don't know the exact flow card but I know max flow was 380ish. the build will be 11:1 with a quench of approx .035" using a custom CP piston, Carrillo rods, and dragon slayer crank 4". W9 mopar intake not sure on the carb. I will have a 9.5" converter built by Dynamic, 727, 4.10 gears, 28" street tire, custom stainless headers 1 7/8 or 2" stepped headers, 3" exhaust run through pypes mufflers turned down before the axles.

The rockers are Jezel off sets 1.6 or 1.7 I can't remember.

Cam will be a solid Roller..
I have a 250 dur. 630 lift cam that I can throw in.

Whats the best streetable cam I can run that makes power tons of tq and most importantly has great manors.. I will only race the car on certain occasions like mopar madness, T&T, etc..

considering that youve built what is to most sbm mopar guys an all out bullet, why stop now and skimp on cam? iirc w9 heads flow crazy at higher lifts, can u provide us with the whole flow chart for them?? with the 1.6 or 1.7 rockers you should be up in the mid to high 700s with that .630 cam and that will probably work well. but again do you know at what lift the heads flowed 380?.. those heads have the potential to make 800+ horsepower with the right cam and more compression. either way you built one hell of a motor and you would proably be best off having the persone who ported those heads pick out a cam for you........ that sum ***** is gona make a but ton of power even with a mild cam.....and if its to much for you sell it to me and ill run it on e85 with 15-1 comp and a 800 lift roller and make 950 horse.......good luck with it!!

Thanks for the kinds words.. I think.. lol.. I know it's somewhat of an exotic build but a the end of the day it's just a street toy. That's why I wanted help with the cam. I know I'm not going to spin this up to 8000 on the street so I need the tq and pwr to come in sooner. If it's too much I'm sure I can off it to some one.. This is a Ray Barton R1 block that has a ton of $ in just the machine work alone, not to mention the high end rotating assy... those heads are the tits too but I have to check about the actual flow card to get some numbers to you.

The biggest cam that you can use is the one that doesn't drive you crazy.

I have used a purple Hyd. cam @ 292/.509 and it drove me nutz!

While currently, I am running a Comp solid cam that is about 6* larger and more lift and I like it a lot.

Run a cam with the duration that fits the RPM range your driving in with as much lift as you can stuff into it.

LOL... Couldn't have said it better myself

I love the sound of a huge solid roller thumping but if it was a car I drove very much I wouldn't go bigger than 260 at .050" and .650 lift on a 108 center (I know, call me a wimp). But I know some guys that'd run a 285 at .050 with .800 lift cam.

One nice thing is with those heads it's gonna make crazy power even with a small'ish cam.

 

[rumblefish360]

That is about the cam I would run for my next engine...up coming... with 1.6 rockers.
.600 / 1.6 X's 1.6 = .693 then minus lash

An member over on moparts has similar built and says he has 278 on a 705 lift... with that his tq peak is at 6000 and hp is 8000.

 

[rumblefish360]

Oh sure, the bigger the duration, the higher the peaks will be.

 

[USCG CHARGER]

yup no way I'm going to spin it like that in street trim.

With a 28" tyre and 4.10s you're going to need to turn some 6K+ rpms when racing over the quarter.
I'd say something in the 260s range, with as much lift as you can get.

 

[Rob R]

I'd call a cam company like Cam Motion/Bullet/Engle/Comp and ask them to grind up something that will work with your parts and driving needs...
That's the way to go...IMHO

 

[moper]

That's a little different than you were talking about before. Went from factory iron, to W2s, to W9s? Wow. Way too much head for what you are intending to do. IMO, big mistake. A 9.5" convertor with a moderate stall and gearing will be horrid, idle's going to suck, as will low rpm response... the reason those engines make power so high is a combination of the cam and heads... Just changing cams will not go too far in lowering the power curves because the engine is going to have to reach 5K rpm to even begin to use that port. I'd want to see the heads flowed long before I said anything about a cam. Think about it... you are talking about 45-50% gain in flow over 260cfm heads. I think you should seriously rethink your approach.

x2

hey if u want ill trade you my hogged out x heads for ur w9s....... they will certainlty be more streetable at 6000 rpm. like i said... what u have built is an all out bullet. those heads wont start making any power till 5 grandops:

 

[USCG CHARGER]

Well I have already paid for it so it's going in the car...if I hate out then I will throw s turbo or sc...it's strictly for the wow factor anyways. Just a toy.

 

[moper]

lol... cool Then add 1pt of compression, 4.56 gears, and an 8" convertor... And hold on.

12:1 on pump gas? lol no thanks

It will be fine. The cam you'll need to run is going to have so much overlap, you wont be near detonation. Seriously... Something in the 250-260° .050 range will not get into detonation issues. Especially with a tight quench and aluminum heads, and you'll need it to wake it up. Use the calculators and see what the cylinder pressures end up at...

I'm still not opposed to running a larger cam.. I just want something that has nice manors on the street :banghead:

X's 2, it becomes very doable with a large cam like above.

This week I will get the cam card and post the finial specs... I thought they were 250/256 @ 050 with 600 lift.. if I'm running 1.7 jesel rocker the lift should be fine.

 

[rumblefish360]

That be .080 more lift. It should increase the intensity of the cam a good little bit.

Enough to be adequate for pwr and street ability?

IMO, you've already removed that possibility with the top end choice. The cam is what I'd define as mid-size when used in a 4" stroke street/strip engine with properly matched heads (in the 250-280cfm at .500, and 200-220cc port volume). The W9's volume should be 260-270. Some really oversimplified basics: the stroke increase is about 12% over a 360, and 21% over a 340. The W9 port volume is 230% or more larger than the RPM's 171ccs (around 240cfm at .500), which are slightly larger than the factory X/J/etc heads. The huge port and plenum volume will mean very poor idle quality and mandate a higher than "normal" idle speed, and poor off idle/low rpm response. Again, you cannot "get", without some "give". I think you've gone so "racey" on the heads, no small cam is going to help. You have to open the valves far enough and for long enough for the port to work. The larger the volume, the more airflow is required to make the whole system (like the carb) work efficiently. For efficiency at lower speeds (idle to 5500) the head ports have to work at low and mid range lifts. This is much more critical than any peak flow figures. Which is why I say I don't feel any cam be spec'd until the full flow figures are known and reviewed.

I would just try the cam you have, see if it likes it......but I must say, I really don't understand you reasoning for the build. Having heads that flow 380, the race block, Jessel valve train ($$$$$) with a small cam that doesn't leverage the head flow is a crime. It's like building a drag car with the best parts to run in the 9's and INSISTING on using an open differential rear end with 2.76 gears....it just doesn't make sense to me.

Not trying to step on your toes, its just if it were me, and I spent that much on a motor, I would expect nothing less than single digit 1/4 mile times.

I would talk to Bullet cams for a custom grind.

 

[USCG CHARGER]

Thanks for your help fellas..but I got a smokin deal on the entire package...less than I paid for a basic eagle 408 short block...I'm gonna run this & have fun... sorry to bother you guys.
