stroker cam ?
Will a comp cam XS290 solid lifter cam be too much for this combo?
cam specs- 290/298 252/260 .576/.598(1.6 rockers) 110LSA
Stroker 4.040 X 3.75
forged bottom end
11.1 compression
200cc Pro-topline alum. 2.02, 64cc
victor jr. intake w/1" HVH super sucker spacer
harland sharp roller rockers
750 speed demon carb
1 5/8" headers ( 1 7/8 hookers w/ sidepipes eventually)
4spd 3.73 gears
I want a 6,500-7,000 rpm motor and mean sounding idle, but I still have to power my power brakes. Will this cam be a good match for this combo?
Thanks,
L-82Kid

IMO, it's got quite a bit of duration, but you're running a 4spd, so it may be tolerable....expect to sacrifice some bottom end torque, but it seems you are looking for top end HP so overall it's a good choice if your car is more "strip" than street.....as for vacuum, I'd call Comp Cams and refer to their recommendations for your needs.
P.S.......It WILL have a wicked idle.

thats alot of duration.....Heads might be a hair small for the cam, (2.02/1.60) is more suited for "hot street"....with that cam you might want to think about vacuum assist as you will have very little.My setup is similar (383/forged 10.76:1..competition port/polish on aluminum rpm heads 64cc (2.02/1.60), mighty demon 750, rpm intake, 4-speed....I went hydraulic roller 286HR .56/.56 lift and only 230/230 duration @ .050......still gonnna have a mighty idle. good luck.

I'm running a Comp cam hyd in a 383
280h, 230-230, .48 lift, I also have 1.6 rocker on top of this.
I have 12'' of vacuum at idle, I have not checked it at speed. It is just enough to run the vac advance, headlamps and power brakes.
You may have to run a vac pump with that cam.

It will have this alright! mean sounding idle
I'm kind of a wimp when it comes to solid cams. I always went for go not show. The biggest cam I used in my 383 with flat top 64 cc heads was 240/248 112 lc.
At Wed. night cruises many cars had bad a$$ sounding machines with radical cams like yours. The 4 speed will help. I have a 13 meg movie I did with my 383 of a startup and idle. My digital camera sound kind of goes into overload from the noise. I could e-mail it to you.
I ran mine to 7500 rpm on a regular basis and the hot rodded Vipers could not take me on road racing courses on the straights from 70 mph -140 before braking

That is the exact cam I just put in my 385 stroker. Don't let them tell you it is to much duration. It is not. It runs fine. It is a little soggy below 2500 rpm but hang on after that. I have run it down and cruised it at 2000 rpm with no problem. My heads are slightly smaller but that should not make a difference. If you want a low rpm cruiser step down. If you want one that really makes power than stick with that cam. I am going to run a 825 Mighty Demon once I get the fuel line hooked up. Running a 750 DP that is to lean right now.

The stroker gives you more torque in the low end, mine starts to pull good at 22-2300 and comes on hard at 2500

No sound clips yet. My new water pump has been giving me fits. I'm going to put the old one back on. I have not put to many miles on it yet. Fixing up the fuel line today and should be back together tomorrow. Just in time for rain.
I don't have vacuum brakes. I have a hydroboost. I used to run a 248 @ .050 with my 350 and it idled at 11 inches of vacuum so this motor should be about the same.
