well i have notice some thing here on sm

there really is no feed back on the brain cower cams at all in any shape or form in any of the stages

i find this kinda sad really

so i was going to get set of re grind done but now i can't cause i wana rasie the rpm and now i risk spitting shim

so what is the feed back form bc
264
272
280


and then custom spec's that you guys have

I have a set of BC 272 cams that I was going to run in my build, they are still in the box on the shelf. After talking to Ian about them I decided not to use those cams. I did buy a set of billet cams from Rich at SIP. Those cams are
9MM and 234 degree duration at .050 lift.

doesn't cower just do regrinds from the base lobe if so that make your shimm pretty thick

935 offers this but say's it regrind

and nothing is listed on there site

i just don't wana risk spitting shim at 7000 rpm or so

this is what i wanted to run befor 264 and 8.1 mill lift from colt cams



has any one tried this befor ?

why not just invest in shimless buckets and be done with it?

Where can one get these shimless buckets in our size?

its not cheap to do... and if you dont do the math right, its expensive.

Sweet thanks! I just might have to do those up before I start trying to rev to 8500rpm.

Back on topic now.

 

[gaboonviper85]

still worth it...especially if you are doing high rpm pulls! it will benefit the valve train with less weight and more dependable...but its also one reason why im not going with aggressive cams with my motor build as it requires alot more money.

well that drive's up the price to the point were drop in cam are about the same price

i have alot fo oem shims kicking around


now the key here is how thick of shim can you run tell you risk spitting it out ?

Its usually a problem of them being too thin when they kick is it not?

Spitting shims is more a geometry issue with small base circle regrinds as the shims end up thicker/top heavy and the cam pushes them to the side as it turns.

 

[NashMan]

yes but how thick cna you go tell you start to worry

I run the 280's... I think that when are deciding on cams it is critical to know what your head is capable flowing and at what lift and match the cams accordingly ....



Here I go again with crazy talk

i was looking into thou cams they seam like shit for low end and will really hurt my brakes

how do you like these cams and what the power band like ect ect

teh more the info the better this thread gets

 

[IJ.]

Stock

Brakes are fine here and the motor makes good low end power.

 

[NashMan]

you run a stock cam thought you had diffent ones

 

[IJ.]

I meant stock thickness shims is when you start to worry

 

[suprarich]

Nash, if you run a regrind, don't use a thicker shim on top. Place a "make up" shim under the bucket that is the same thickness of the amount of base circle that was removed. Then just continue to use the stock shim on top. A good key to not spit a shim also is to run the cams on the tight side of clearance in respect to lash.
