ok i bought a new cam for my stock camaro and it a 631/631 lift and at .050 it 230/243 duration and i need to know what all i need to change to put this big of a cam in. i just bought new spring that can handle a .631 lift and i know i prob need a vacuum pump but not sure what else i need so can you tell me what i NEED.


mods are long tube headers, no cats, borla exhaust, slp MAF, slp cold air and i tune it with HPtuners.

Who did you buy the springs from? I woulda went with .650 springs to make sure it could handle more then the lift.

You'll need the basic cam changeing kit. Oil pump, timing chain, gaskets, etc

Id suggest LS2 timing chain, Ported and shimmed ls6 oil pump, and you can get a gasket kit from just about any sponsor on here

you don't need to change it, its just one of those cheap insurance things you do as long as your there type of things. if your car has low miles you really don't need to do it, just recommended by most. YOu don't need a vac pump you can get by with a vac canister and save your self a couple hundred. My friend has a ms4 and he just added one and his brakes work fine no matter how much he stops and his brakes worked prior to the canister just really shitty. if you plan on going fi anytime soon just buy a vac pump then. one less thing to buy in the future.

ok well ill look into an oil pump but i just have a low buj but if it means my motor the cam can wait until i save up. any thing eles i like have to have?

Oil pump is just for insurance like stated above. Also i forgot youll prolly need a little longer pushrod (most likely 7.425 as long as its stock un milled heads) but i would measure with a pushrod checker

ok well 1 question wiith that big of a cam wouldent i need to go smaller push rods cause my lift is 631/631 and lob sep is 114 deg. and isnt my rockers 1.7 from factory? but i am getting new lifters springs came in today and im getting the gasket kit. and how would a vac canister help keep my vacuum around 20psi?

Zach79Z

Aftermarket cams are a smaller diameter then factory cams which is why you need longer pushrods, but id just check them anyways. Factory rockers are 1.7. Id suggest ls7 lifters. Very good lifters for the money. And i dont know about vaccum pumps so maybe someone else will chime in on it

thanks alot man for all the info.

No need for vacuum pump. If you get LS7 lifters then measure to get the right p-rod length, I would say 7.400 will work but measuring is a must.

Listen to that man right there^

my brakes are going to suck though right?

and i sure will do all the measuring

and do i have to pull the motor to pull the heads off?

PREDATOR-Z

no, not necesssarily, that cam will idle at 900>950 rpm.
no heads come off while motor in.

Check this site for install.

It is all in there.

If you pull the heads add head gaskets and bolts to your list along with intake/exhaust manifold gaskets if you have higher mileage.

well the lifter have a wear pattern from the other cam so when i put my new cam in wont it hurt the cam?

PREDATOR-Z

It is a good idea to change lifters if above 60k miles on the originals

Port the ls6 heads. Viperbluelx on here swapped his cam in his ls6 vette and dynoed the car, then ported his ls6 heads and redynoed it and gained 30rwhp just from porting them
