comp cams

96sickstang · November 9th, 2009, 09:41 AM

I had purchased some comp cams awhile back they r slightly used with 2000 miles ob them but I only need one for my car right. Wat all do I need 2 do to install the cam and will it raise my compression ratio also

You do need both of them. Even though the engine is SOHC, there are 2 in it. There is 1 on either side of the engine block. A DOHC would need 4 cams i believe, 2 on each side. As for compression ratio i dont believe it will since cams are the key point in induction it creates HP by sucking more air into the system. To increase your compression ratio you would need to get a tuner. (Not 100% sure on the compression question)

Single Overhead Cam means that there is 1 camshaft per head driving both the intake and exhaust valves, and there are 2 heads, one on each side of the engine, so yes you need 2 cams.

The only thing that will change compression ratio would be changes to the volume in the cylinders. Cams are not inside the cylinder. Compression ratio can creep up from carbon build inside the combustion chamber, but other than that you would have to change internal parts to change the compression ratio.

Ok so do I need to install both of them to the both sides. And is there a write up on how to install cams

You cannot change your CR without either changing your heads, head gaskets, pistons or cylinder bore.

You need both cams and there is a write up on it in the stickies. Use the SEARCH feature and it should come up.

depending on what cams you buy. You will need to get new valve springs.....
