N/A Cam in L28ET

[Ben's Z]

Two feckless turds in a row now have hosed me on back to back P90 cams at Hybrid Z and my patience is wearing thin. My motor build ( http://www.classiczcars.com/forums/thread46890.html ) has been set back 4 weeks from actually enjoying my car because of all of this. A couple guys over at hybrid suggested running an internally oiled "A" cam from a 77-81 N/A motor (Think I got my dates right). I know there are not a lot of turbo folks over here but any help would be great. I could pull my cam out of my old motor, towers and all and let it rip. Doug at Awesome Z said he has some cams too. I don't know:ermm: I do know I have been banged out of nearly $300 in either junk or nowhere to be found cams from hybridz members.

An NA cam would be fine, but aren't the p90 valves shorter length- not sure what that would effect . Hell - you could just throw on the NA head complete and b done with it!!'

Compression would be too high. I think the combustion chamber is bigger on the turbo heads.

I always thought the P90 and P90a heads were tubo and the P79 head was the NA head. If you stay with a P90 it shouldn't be a problem. The P90 was used in 81/82 and the P90a with hydraulic lifters came out in 83.

If I use my cam out of my 77 should I use those cam towers or the ones out of my P90?
