Im building a 355 with just about every possible bolt-on, along with ported heads and ported intake. The heads flow 268cfm at .600 intake, and 203 cfm exhaust at .600. The guy that had the heads before me ran a 236/242 cam and was running 11.7s in the 1/4. Should I use this cam or something else? thanks (ps- i think my springs are good to .600)

 

depends if you handle that cam, its going to be big for 355.

 

ill probably end up going the custom route, but i dont really know what kind of numbers im looking for. ??

 

any ideas?

 

I had a 236/242 xfi cam in my 355 setup and it ran great. The heads were the limiting factor and it made 372 rwhp at 6100 RPM. I suggest going with a shorter LSA than shelf cams if you can. Check out the voodoo lineup from Lunati. Those cams are badass.

 

yes the springs that are on the heads are comp 987 good to 600
