Text Box: IMPORTANT NOTES: Cam, valve timing and lash may vary. Refer to Degreeing Instructions and Installation instructions supplied in the cam box or our catalog for proper setup of your new camshaft. This cam has a rapid acceleration rate and will require the use of billet lifters. GP8250-2 Billet Lifters are required to insure durability. We recommend welding the lifter bores on your block and “chamfering” your lifter bore approximately .030”. Frequently check the condition of the valve spring retainers, lifters and valve springs. It is a good idea to change your springs, retainers and lifters at every rebuild. In order to achieve controlled valve float and to achieve maximum performance at high RPM, it is ESSENTIAL to properly set-up your valve springs. Improper set-up of your valve springs could result in damaged parts inside your engine and lost performance. See recommended spring pressure set-up at the bottom of this page for the proper set-up. Ignition timing can be referenced when the right leg of the coil is lined up with a line about 3/8” from the leading edge of the magnet on the flywheel. To find the exact line on the flywheel you must use a timing light. Check installed height WITH the lower retainer on the valve. Check the spring pressure WITHOUT the lower retainer—spring only.
