May as well talk to a cam grinder about what compression ratio to make the pistons. The cam and compression ratio have to match rpms and octane of fuel to be used. Gas manifold, five angle valve job, blend the rough edges out of the ports. Dry air cleaner element conversion. A distributer will allow spark timing to vary and follow rpm. Won't tend to kick back when lugged to low rpms. [Reply]   [No Email]

Then the crank, and lastly the compression. The engine needs to breathe, and to be able to utilize the raised compression, the valve train and all of its components need to be in top condition. If your not building a puller, then stroke wont matter much, leave the crank at stock specs. Your machinest will make sure the crank journals are true and up to specs. As B&D stated, a five angle valve job will make a difference, as well as a port and polish. But you know how much you can spend, so if your budget is tight, your money spent at a good machine shop will be well worth it. [Reply]  [No Email]
