No it wont fit, And that is big cam for a 350 cube engine, without some serious mods.

Can you please tell me the reasons why this cam wont fit a roller engine?

Roller cam block used a retainer to hold cam in and also uses different timing gears, The cam can be made to work but timing chain will hit/rub the block. to many good cams out there for the later model 250 roller blocks, why buy something that isnt meant to be and possibly have issues.

My recommendations for a roller cam are either the Comp XFI268HR-113, (218/224, .570"/.565" lift w/ 1.6, 113 LSA) or if you want bigger, the Comp XFI280HR-113 (230/236, .576"/.570" lift with 1.6, 113 LSA).

WOOW I got it http://store.summitracing.com/partde...w=1&N=700+150+ its for factory roller engine woohoooo

According to the specs that is a retrofit cam, not for a roller block, and the CC306 would fit and is a good cam, What engine setup are you running this in. The specs on that last cam is going to be real radical with a 107 lobe seperation, if your running FI setup with this cam it is going to be a major bear att tuning.

The CC306 is a nice cam, but it was designed over 10 years ago, practically ancient now. The two I listed are brand new cams, only a year old.
