Tweet

there is lot more to this every cam book as a step by step how to do . i do them evey week . i check at mild lift . you will need set up springs .you will have to work out lash for solid cams and work in pre load on hyd cams most of the time it will not change much i still do it . there two ways to go custom push rods or shelf stocking push rods many come in only .050 length on the shelf stocking push rods . so if you need lets say a 7.520 your only going to find a 7.500 or 7.550 but some like Trend Push rod may have what you need in stock if your loking for a 7.520 . other then that it custom made to your size . you need to know that with a hyd that the test springs is not pushing the valving down in the lifter giving you a false read for print out on roller tip . at the end of this there 3 ways push rods are sold . over all on push rod size.Theoretical no oil holes .Actual as to real size but oil holes can throw this off. Gage length pain in the ass .not every one sells push rods like this . so knowing what you need for push rod size is the way you checked for push rods and knowing how they are selling them
