I have finished decoking the heads and I then started to strip some stuff on the short motor. I removed the fuel pump and then the bottom pulley and the harmonic balancer or damper. I then removed the timing cover and there was loads of slack in the timing chain as my mate suppected. I have the new comp cams roller chain to go in there so I had a quick trial fit of them as all the timing marked are lined up.

I then took out all the lifters and labeled them so I know where they go back if I need to. Then I removed the cam which is in good condition all lobes are good. I noticed it has an H stamped on the end so I stopped my work there as I have to decide what cam to put in there.

So I look up in my Jim Hand performance Pontiac engine book and a H cam looks a pretty good cam advertised duration 302/320 duration @ .050 224/236 and 115.5 lobe separation intake centerline 113 And further on I read it is know as the Ram Air III cam as far as I can see the lift is only 0.407"

Now I am wondering if I should just go with this Ram Air III cam or is it worth go for the higher lift of the above cams?

what do you think I was thinking of the comp cam 260H or the 268H or 275DEH

I looked at the spec of Pontiac valve springs and the spec of comp cams 988-16 springs and found they were almost identical can I use my stock valve springs with these cams
