I was wondering what valve springs people were running with their e303 cams. I'm running crower single coils, and i'm trying to see if they are too weak for the cam. If they are, i'm guessing that i need to run double coil springs.

any insight on this for me???

thanks,
jeff

 

Crane Part Number: 96803-16 is the spring for the PowerMax 2040 (aka E-303)

 

you wont NEED dual springs... i am putting in a bigger cam then the e cam, and yea right now i have a dual spring set up for them, im going to return for a single spring set up w. more seat pressure.

 

as a matter of fact, e7 heads dont accept dual springs w. out machine work... as for your gt40ps i dont know

 

Right on DIMEBAG!!! Dime has you coverd!! anyway ......just get these and you'll be fine!!!

without clicking any of those links i'll say 120 lbs @ the seat

 

so should i even worry about getting different springs??? It seems as if the valve guides are too wide to run dual springs on them anyway, i guess that explains dimebag's machining theory.

also, can someone explain to me what the damper does???

 

dampeners do exactly that.

they help with the vibrations from the springs opening and closing - it smooths things out up there.

 

should u worry about differant springs from what? stock... DEFFINATLY... with out question

and what i said isnt a theory... its something i found out the hard way... i have these nice asscomp dual springs sitting here and no use for them..
