i been lookin at cams. i was planning on using either a edelbrock torker 2 or eps manifold. i been lookin at jegs brand cams and like this lift and duration 465/488 282/292 but i can get a new rpm cam kit for 130 with my shop discount at auto parts store. 488/510 308/318. just wanna know if anyone has is and how they like. it. does it hold good vac. or will i need a vac canisster to use my power brakes. any pvc issues when installing and what rate of springs did u use. i can get a good valve spring set rated at 510lift but i think that will be cutting it close for that rpm cam. or would i be able to get away with it. ive always used a higher rate spring that the lift on the cam.
