cam and lifter Q's
what is the best cam lift and duration i should look for when picking out a cam for my 390 i want it to be a performace cam and if i get a new cam do i have to get new lifters to, i have a cam that hasnt been used before and ots a performance cam but i do not know the specs on it, how can u check to see what the lift and duration is on it, any info would be great thanks.

You can check the lift with a set of dial calipers, but the duration would require installing it in the block and then checking the duration with a degree wheel. Are there any Id markings on that cam?

If you don't know what cam it is, don't use it
You need new lifters with each new cam
If you take a cam out, take the lifters out and place them in a box with dividers and mark them, as you can reuse those lifters with that cam.
Id go with the crane 901 as most people are running
I have a Crane came in my truck and I love it

I got mine from Jegs... 99.99 Dynomax
270-343901 Adv. Duration: 260º/272º
Gross Lift: .501''/.533''
RPM Range: 1200-5500 $109.99
Is the cam I got. Chugs just a bit... More in gear
Runs great, great low end power
The 941 may or may not work with your stock non-adjustable things. It's been discuessed here, but for the safety of things I went with the 901
Some say they can run one with the 941 lift, some say they couldn't

Wrong, Jegs does not sell that cam for 109.99 WITH lifters
I thought so myself, but it came with no lifters, called them up and they said it was cam only
Buy them from a local parts store. I paid 55 for a set of lifters for it
