what cam with forced induction?

whats a recommended cam when going with forced induction?

rockers,springs?

something with low overlap . Overlap is a bad thing for a poweradder. It pushes the boost right out of the exhaust port. Actually some stock cams are really good for a poweradder.

when looking at cam specs,which number representes the over lap?

[NastyZ]

Also you want a high LSA . Like 114 or better. What I mean is ....
ZZ4 specs I have here ....208/221
if it were for boost it would look like this 208/210 . Less overlap .

Don't forget the bigger LSA . LSA also kinda reduces overlap aswell. So you may be able to get away with a bit more overlap if you have a really wide LSA. Like the stock L-98 cam of my year had a whopping 117 LSA . It actually would make a great boost cam.

is there somwhere i can read up on the different cam specs,like what all the numbers mean and how they work together,like what a LSA is?lol,im from the import scene so i only know enough to make me dangerous.

Turbo or Blower?

[one eyed willy]

ill be doing a turbo,on a 396 stroker.

[Ed Blown Vert]

Then you would want a reverse-split

wow ed,nice **************** ride.looks like i could learn alot from you.i have not recieved my motor yet,396 stroker,looking to put some afr heads on it with 76cc chamber and run a turbo.heads will come with valves and springs,not sure if those will need to be replaced and i need to figure out what cam and rr's to get.

Keep the overlap below 5 deg at .050".

Overlap = (intake duration/2) + (exhaust duration/2) - (2 x LSA)

For instance, my cam is 224/236-114

Overlap = 224/2 + 236/2 - (2 x 114) = 2 deg overlap

Choose the duration to fit the rpm range you want. 230 will peak around 5800. Add 400 rpm for every 6 deg duration. For instance, 236 will peak around 6200.
