My new 350 engine

...
Now, this is my first engine build, and my first question is: What cam should I get for rock crawling?

Something that comes in real low in the rpms.
They are ?? heads at the moment.
Rocks are the main thing. So, a low RPM.

Call comp cams and tell them what you're doing, they'll be able to steer you in the right direction.
I'm running a pretty aggressive cam in my 383 (by rock crawling standards), 276/284 (214/222 @ .050") .488"/.509". You've seen how it runs, I have absolutely no regrets with that cam.
Remember, however, that a bigger cam in a bigger motor will have a similar powerband to a smaller motor with a little smaller cam (I'm making up numbers here but a 260 duration cam in a 350 might have a similar powerband as a 265 duration cam in a 383). Or so I've heard.
IMO, Chevy V8's have such flat powerbands that you have to get REALLY aggressive with cam profiles to hurt the low end. Besides, for the most part you don't need much power in a rock crawling truck.

Pictures already taken , now stand that crank up if you can , its better to stand them up so they don't bend .
I likey the bottom end so far . Should be sturdy enough for a long life if its only rockcrawling . Those rockers are beef too . You need guideplates and screw in studs now , because the will to spin it will come over you once in awhile I'm sure

That's true...unless you have a cradle for it stand it up somewhere it won't get knocked over...Pictures already taken , now stand that crank up if you can , its better to stand them up so they don't bend .

Should stand the heads on end as well.

Guess so..I always used a piece of cardboard on the concrete floor to make a little cushion.

In all his noodly greatness the FSM recomends a Comp XE250H. Good all around low end high torque cam with a stock stall convertor.
May THe FSM touch you and your engine with his noodly appendage and bless you.

looks like you have some junk laying on your floor. Just send it to me and Ill gladly dispose of it.
Looks good man. its fun building your own motors. I built one for my last truck. It ran good. Just had an R/V cam in it. Had plenty of power till about 4500 rpm.

you can pin the studs as well as long as your not going that crazy with the cam or the rockers.are thoose 1.5?
also if thoose are camel humps what are you doing for accessories.all camelhumps didnt now have holes in the front of the heads for assecories.any reason on thoose?mine has 882s now but will be getting vortecs soon.vortec heads are much more bang for the buck.are you still on tbi?

judging by the center bolt valve covers on those heads i would say they are vortecs or something of a TBI swirl port nature.

Think it'll be a couple more days. 
I'm not assembling it myself though. I know how but just don't feel like it. Plus these guys know more than i do.
Looking forward to seeing yours run in a week

those aren't "camelback" heads. The centerbolt valvecover never came on the camelback type heads. The have this mark on them:
at any rate, I would shoot for a reputable cam co. and look for 210-220 duration @.050. With .430 to .460 lift at the valve. This would be a great torque builder, and would perform well up to 5000 rpm or so. Big port heads (highly ported) aren't really what you want for torque building on a 350.

still no accessory holes,hmmmmm? *scratching head
camel backs didnt have accesory holes.the cars they were used on had no power steering and the alternator was hung off a mount that tied into the header.you can still buy it at auto zone.i ran theese heads on a well built 408 one time
A lot of Camelbacks/Doublehumps/Fuelie heads don't have accessory holes. Some do. Either way, the heads in that picture are not camelbacks.
