I need to replace my cam. And cam bearings.I have new lifters. If anyone has a new set of cam and bearings with the groove, I would like to buy them
I would not know. Not even sure if when installing a stock cam if you can use the front grooved bearing. Someone educate me. Just want to do all I can for oiling while its apart. And also will I need a cam tool?
You are right. It is a 70,000 mile bottom end but I am not sure which cam to use. Dont want to get into changing rocker ratio. Just a cam that would give maybe 20bhp and a small slope, but a comfortable driver.
Is this a stock bottom end 70 455? If so, you can safely use a healthy amount of cam. http://www.taperformance.com/products.asp?cat=160 Take a look at the cams from TA Performance. Tell us what you like and we will steer you in a great direction.

I have been there many times. I need advice. My other 70 comes in for hp at 580. It is a big build with tremec 5 speed. I am in the process of installing the holly snyper. No matter what cam I put in this 70, it might impress the next owner. I just want a nice Sunday cruiser. A snappy off line cam with nice drivability is what I am looking for.
Get the cam Kerry is selling. It will add some power to a stock 455 and will require no fuss. No lope to talk about though. If you want to rev it to the max it might require some Stage 1 spings. Crower's rev range is goofy on all their cams. That cam is good to 50-5200. Probably makes peak power above 4500 depending on what is around it. The bigger the cam the more performance equipement it will need around it to work good. The smallest cam is usually the snappiest off the line. If you want some kind of lope you'll have to start adding duration and overlap which will start removing some of the "snappiness" at the low end. If you need some lumpiness get the TA C110. IMO it is very noticable. That's as big as you'd want to go without killing the low end. Probably would like to have some extra stall in the converter to keep the snappiness off the line. Stage 1 springs required. For good low end but some kind of lump in the idle you want the least amount of duration with a tight lobe center and this is about it. +1* overlap at .050" lift. A stock cam is about -25* overlap and even a factory Stage 1 is about -15*. TA made a version of a Stage 1 which would have -9* of overlap and IMO you would know there is some kind of cam in it but you'd have to check with them on availability. Just for reference +10* is very, very noticable. http://taperformance.com/proddetail.asp?prod=TA_C110-455 No problem with using the grooved bearings with stock cams but you will need a cam bearing installer. On a lower mileage engine, if I was doing it at home I wouldn't worry about #2-4 if they looked good. If you get a professionaly to do it do all of them. Make sure the grooved bearings are installed according to instructions.
