today i bought a crower beast cam and i was wondering what people thought of them i am building a 355 with vortec heads dished pistons rpm air-gap manifilold 750 edelbrock carb double roller timing stock crank at 10/10 and headers does this sound like im heading down a good path with my motor

You'll have to be more specific, there are several different size grinds in the Crower Beast line.

[Danny1986]

oh hell i thought i wrote it in the adv. dur is 288/298 lift is 444/467 and rpm range 1800 6000

[ericnova72]

What is the duration @ .050"?? Advertised duration is pretty meaningless.

[Danny1986]

im not sure on how to tell that i ordered it from jegs today so all i can go off of is what was in the catalog and heard they were good cams

[ericnova72]

I loked at Crower, seems you have the #00904 Torque Beast - low to mid range torque with daily drivability. 214/224° @.050", 112° lobe seperation, 1800-5500 rpm powerband, redline 6000rpm.

Beast cams have been around a good while, they are decent cams, not exactly the latest designs but they do work well. Appears to be a good match with the rest of your parts.

How well the whole packege works is going to depend on what it is in, what it weighs, and what rear gear you have in it. Its a solid 340-350 hp combination and will make real good torque.

good deal thanks i was starting this build with the thought of around 400 but it is my first build so still got alot of learning to do i am putting it in a cutlass supreme im going to match it to a th350 that i will rebuild and put a shift kit in and probably run 373 gears will i need a stall converter and what size should i go with i did buy a high flow water pump and high flow fuel pump also

[ericnova72]

2400-2600 rpm stall will work real well with that combination, should be a lot of fun in a G-body with 3.73 gears. Don't forget a posi unit, you'll need it.

Not a bad choice at all for the heads. Hell of a lot better than one of the thumper line of cams, IMO- which a lot of new guys get sucked into.

[Danny1986]

awesome thanks for your help what would you recommend me getting a new rear end from or can i use the one i have this is gonna be a some what daily and highway car

[Danny1986]

Yea i was told to get a thumpr cam but in another post i had someone told me they are pretty much a novelty not much power i looked into the isky cam i was recommended and into this crower and i was ordering other stuff from jegs this morning and thought i would take the chance cuz it seemed to be what i was looking for

[F-BIRD'88]

Its a good mild/moderate street cam for your 350 vortec motor.

The power range is pretty accurate off idle to 5500 rpm.
3.73's is a good choice.. You can use a stock GM th350 12" "2100 stall" torque converter with this cam..... but if you like real hard launches off the line a 3000 stall converter works great. It's not too much.
if you want to go fast and launch hard get the 3000 stall.

On 350 with a dished piston install the vortec heads with a thin felpro #1094 .015" shim style head gasket to ensure decent compression ratio or you will come up short. This cam likes compression 10:1 is not too much.
the fuel mileage is good as far as you can keep your foot out of it.

You need to tell the board what vehicle this engine is going in, before any specifics can be given about the rear end other than generalities.

Even the ratio is hard to pin down w/o knowing tire diameter, vehicle weight, trans type/ratios, use of the vehicle, etc., although "...a some what daily and highway car" does help a little, at least.

Hint- It is always better to give too much info rather than not enough- as I'm sure you'll realize if you "put the shoe on the other foot".

Somewhere up the page i did put that it is going in a 1988 cutlass supreme and will have a th 350 wheels and tires are basically stock size maybe a little bigger

I see "Cutlass Supreme" mentioned- but that covers a lot of ground.

Your '88 has a notoriously weak rear end, for example. Earlier Cutlass' came w/better rear ends. The weight difference is in your favor at least, between an '88 and say a '74.

To see what your rear gear ratio is now you can check the RPO code if the sticker is still in your car somewhere (glovebox, console, under trunk lid for instance). More at post #7.
