i am building a 2276 engine. all the good stuff.
will be driving on the road and possibly track, but what cam should i run, there are cb straight cuts on a 82 by 94 chev journalled nnitrited 4340 crank with 5.6 rods.
42 x 37 in the heads with stage 2 porting.
this car will be driven quite occasionally to work.

Any specs on the satge 2 heads?
Will you have ratio rockers?

53 cc chambers, heads are 42 x 37, came from Rod Penrose. flow for 190 - 200hp.
dual springs.
Rod had said the heads were done in the states by a fella called tims?
compression ratio somewhere from 8.2 to 8.5. (hopefully)

i had a berg cam, GB-310, in a 1916, very nice cam, running similar heads and it was very driveable on the street. also used it for a hillclimb. its a good allround cam from the website

GB-309
Engle V26
Both for ratio rockers

If you are going to use a GB-310 or engle K8, get the CB version.
