Attach an angel /degrees disc to the crank shaft. fix a dial indicator to the inlet rocker. turn the crank until the rocker just starts to move. set the plate to read 0 degrees turn the crank until the dial indicator now moves back down. When it has stopped moving read the number of degrees that the crank has turned. repeat the operation for the exhaust rocker. the two readings will give you what size the cam is. of course if the cam is out in your hand the size will be stamped in the end of it.

I have a chevy motor numbers V0701CFA can u tell me more about it


That number is I believe off the timing cover SBC, If you look at the back of the engine where the trans bolts to the block there should be a casting number on top, Get me that number and will be able to tell you what you have there. Hope this helps, Good Luck Randy.

What that mean with sbc h show on dash board ?


Im assuming you have a Mercedes?


SBC H is an anti roll back device on some models. When stationery, push your brake pedal. This will activate sbc Hold. You should be able to release your brake pedal and the car will not roll. As you pull away, it will release itself to stop you rolling backwards.

Most factory small block chevy heads can only take a .500 lift cam unless creative machine work has been done. By looking at the cam shaft card and using a degree wheel this will determine the out come performance and as a general rule for valve train geometry at mid lift of cam shaft the rocker arm should be 90 degrees to the rocker stud. if not a longer or shorter push rod is required . the cam card also gives the free length height of the valves with a closed pressure reading this very important for cam life and helps prevent valve float at high rpm's with full open valve spring pressure.

Change the oil and use 20w 50w oil,castrol,and maybe some lucas oil treatment,you may need to adjust the valves,and make sure the oil pressure is morre than 10 psi,it could be the rod,and main bearings.

How do I tell if I have a hyd. or solid lifter cam in my SBC and how do I tell the differance between the two lifters


If the engine is not apart, there isn't any real way to tell but if you remove a valve cover, on a solid lifter cam, when the engine is turned, there should be one time, when the lifter is on the heel of the cam lobe a bit past the time when the valve you are watching has closed, that you should have about 16 thousandths or more clearance between the rocker and the valve stem (called lash) A hydraulic lifter is always in contact with no gap.(though you may get a false reading if a lifter is bleeding down)
if the engine is apart enough to see the top of the lifters, a hydraulic lifter has a wire clip in the top that holds the hydraulic piston inside from popping out too far. A solid lifter does not have a clip because it dosen't need one (that's why it's solid)
Unfortunately, to know WHICH cam you have, you'd need to remove it as the manufacturer and grind numbers are usually stamped on the back end. (generally 16thousandths lash on intakes and 18 thousandths on exhaust will put you in the "ball-park" though).
