I’m sorry, but I don’t have specific information regarding chamber sizes associated with head number 8878858. This type of detail often pertains to specific machinery or equipment, and typically, such information would be found in technical manuals or manufacturer specifications. If you have access to those resources, they would be the best place to look for accurate information.
This head is a 305 HO head from 87-91 models and the chamber size is 58cc. Also, this head has 1.85/1.50 valves.
76cc
64 cc's
58.cc low torque swirl chamber head
The combustion chamber size of a Chevy 350 stock head typically ranges from 64cc to 76cc, depending on the specific cylinder head casting.
The combustion chamber size of the heads with the casting number 376450 is 60cc. It is possible to install larger valves.
76cc...and those heads are crack prone and not recommended for performance.
Answer If you are checking # on a Chevy head they are under the valve covers in the rocker vally close to the center of the head . the # there can tell you when they were made and for what size engine and also the size of the ignition chamber also a good idea of of the size of the valves installed at the factory .they are cast into the side of the cylinder head,as the name may suggest
Yes they both have 4 inch bores but if the chamber size where the valves is different it will change the compression.
The chambers are 60cc. The heads are from 77-78 307 engine.
64cc
A stock Camaro car has 58cc combustion chambers. You can easily increase your compression by using a thinner head gasket.?æ
