zz4 cam
What would this cam do for me? I have a L98 with full exhaust soon to have runners and intake work done. Probably a 2400 stall. I have the stock L98 cam there now and I hate to say it but i dont even know the specs on that cam. A friend of mine may be sellin his since he is upgrading and was wonderin what would be the better route. zz4 cam or new cam.
Thanks,
Jesse

I've had a ZZ4 cam in an L98 engine and if you have 10 horsepower you should be happy. In my opinion it isnt much better then stock. Go with a comp cams roller with something like 220-225 duration and around .500 lift for a stock L98 with bolt ons. YOu should see low 13s easily.

According to the Tech Data link on this board, the L98 cam specs are 202/207 duration @ .050", .413/.428 lift, 114.5 LSA.
ZZ4 specs are 208/221 duration @ .050", .474/.510 lift, 112 LSA.
If nothing else was changed (runners, porting, chip), I'd believe the 10 hp gain claim. But, with shorter runners, base & plenum porting, AFPR, and PROM tuning, the gains should be much more substantial.
